2. Self-Lubricating Composite Bushing Series (SF-1 / DU Type): Three-Layer Composite Structure Enabling Oil-Free or Minimal-Oil Operation
The self-lubricating composite bushing represents one of MYWAY’s most technologically sophisticated and widely applied core product categories, internationally designated as SF-1 type (also commonly referred to as DU bushings). This series employs a unique “three-layer composite” structural design, with each layer fulfilling a distinct engineering function: the base layer consists of low-carbon steel or copper alloy backing, typically ranging from 0.7 mm to 2.3 mm in thickness, providing the bushing’s compressive strength and structural rigidity to prevent plastic deformation or out-of-roundness during press-fit installation into housing bores; the intermediate layer comprises spherical bronze powder formed through high-temperature sintering into a porous skeletal structure, approximately 0.20 mm to 0.30 mm in thickness. This layer not only substantially enhances the bond strength between the PTFE top layer and the steel backing to prevent delamination under shear forces, but the bronze powder skeleton also exhibits excellent thermal conductivity, rapidly transferring frictional heat to the housing for dissipation, preventing localized temperature rise that could lead to material softening and failure. The top layer consists of a uniformly blended mixture of modified polytetrafluoroethylene (PTFE) and lead-based fillers, with a thickness of only 0.01 mm to 0.03 mm, featuring an extremely low coefficient of friction and favorable affinity for the mating shaft surface.
During actual operation, the PTFE mixture on the bushing’s inner surface gradually transfers onto the microscopic grooves of the mating shaft, forming a continuous, stable, and ultra-thin transfer film. This transfer film transforms the direct metal-to-metal contact between the shaft and bushing into low-shear sliding between PTFE surfaces, reducing the coefficient of friction to an extremely low range of 0.03 to 0.20, maintaining stability throughout the service life without the sharp friction increase observed in conventional metal bushings as lubricant depletes. The bronze powder layer additionally fulfills load-bearing and thermal conduction functions, enabling SF-1 bushings to withstand static loads up to approximately 49 N/mm² and PV values (product of pressure and velocity) ranging from 2.1 to 5.0 N/mm²·m/s without external oil supply or with only minimal initial grease application, with an operating temperature range spanning -200°C to +250°C.
These self-lubricating bushings are particularly well-suited for the following typical operating conditions: enclosed structures where regular grease replenishment is impossible, environments requiring cleanliness and contamination-free operation (such as food, pharmaceutical, and electronics industries), heavy-load low-speed oscillating or intermittent motion applications, and scenarios involving shock loading. MYWAY offers multiple structural configurations including straight sleeves, flanged types, rolled-collar types, and headed types, with support for non-standard designs incorporating oil grooves, oil holes, locating pins, and other detailed features to accommodate diverse assembly space constraints and lubrication method requirements.
3. Bimetal Bushing Series: Steel Backing Combined with Sintered Copper Alloy Layer for Strength and Wear Resistance
The bimetal bushing is MYWAY’s primary product series designed for medium to high-load operating conditions. Its structural configuration features ordinary carbon steel or low-alloy steel strip as the structural backing, with a copper alloy layer firmly bonded to the inner surface through high-temperature sintering to serve as the sliding working layer. The copper alloy layer typically employs tin bronze (CuSn8 or CuSn10P), a material known for excellent anti-seizure properties, conformability, and embeddability, capable of accommodating certain degrees of shaft misalignment and hard particle contamination while demonstrating superior wear life under boundary lubrication conditions. The steel backing typically accounts for over 70% of the total wall thickness, imparting compressive yield strength and impact toughness far exceeding those of pure copper bushings, with static load capacity exceeding 150 N/mm² and dynamic load limits around 120 N/mm². This makes them suitable for heavy machinery applications including excavators, wheel loaders, hydraulic supports, and forging equipment requiring high-strength pivot bearings.
MYWAY employs fully automated continuous sintering furnace lines to manufacture bimetal bushing strip material, with critical process parameters—including sintering temperature, furnace atmosphere, and strip travel speed—controlled through closed-loop PLC systems, ensuring uniform copper layer thickness, porosity, and bond strength across production. The thickness tolerance of the formed strip material can be consistently maintained within ±0.01 mm, with inner diameter roundness and cylindricity strictly controlled. For thin-wall bushings with inner diameters below 50 mm, the company has dedicated multiple fully automated rolling production lines capable of completing material feeding, pre-bending, rolling, sizing, and cut-off operations on a single machine in a continuous sequence. Combined with tungsten steel precision forming dies, these lines achieve stable high-volume output exceeding 10,000 pieces per shift, with exceptional product consistency that eliminates the need for individual fitting prior to housing installation.
In terms of lubrication methods, bimetal bushings are typically designed for oil or grease lubrication systems. Based on actual operating conditions, customers may specify axial oil grooves, spiral oil grooves, or radial oil holes machined into the bushing inner wall to facilitate lubricant delivery from the housing oil passages to the friction interface. For applications with space constraints or where complex oil routing is not feasible, MYWAY can also apply solid lubricant coatings (such as MoS₂ or graphite) to the bimetal bushing inner surface, providing emergency running capability under start-up or oil-starved conditions. These bushings are widely applied in cylinder bores of hydraulic pumps and motors, connecting rod small-end bushings, transmission gear bushings, air compressor crosshead bushings, and various articulation points in construction machinery.
4. Graphite-Plugged Copper Bushings: Pre-Embedded Graphite Lubrication Points for Truly Maintenance-Free Operation
Graphite-plugged copper bushings (also known as solid-lubricant-embedded bearings) represent a specialized product category developed by MYWAY specifically for ultra-heavy-load, ultra-low-speed applications where hydrodynamic oil films cannot be established and maintenance access is extremely difficult. The base material utilizes high-strength tin bronze (CuSn8P) or aluminum bronze (CuAl10Fe3), cast into thick-wall blanks through centrifugal or sand casting processes, then rough-machined and finish-machined to final dimensions. On the friction working surface of the bushing, diamond-shaped, circular, or rectangular cavities are mechanically machined in a grid pattern with predetermined density and arrangement, into which high-purity artificial graphite or a graphite-metal powder mixture is pressed under high pressure as solid lubricant, forming uniformly distributed lubrication points across the entire sliding surface.
During equipment operation, as the shaft rotates or oscillates within the bushing bore, frictional heat and mechanical extrusion action cause graphite particles to gradually release from the cavities and spread across the shaft-bushing contact interface, forming a solid lubricant film with low shear strength. This graphite film effectively separates the metallic substrates of the friction pair, preventing cold welding, adhesive wear, and severe scoring, maintaining stable service life for thousands or even tens of thousands of hours even in the complete absence of external grease replenishment. Graphite lubricant exhibits significantly higher thermal stability than mineral oils, maintaining lubrication function across a broad temperature range of -80°C to +300°C without volatilization at high temperatures or solidification at low temperatures, making it particularly suitable for extreme thermal environments including baking equipment, furnace door mechanisms, high-temperature fan bearing housings, and freeze dryers.
Regarding standard compliance, MYWAY’s graphite-plugged bushings are designed and manufactured in strict accordance with DIN 1494 and ISO 3547 international standards, ensuring dimensional series and tolerance grades are fully interchangeable with mainstream international brands. These bushings offer distinct advantages in food processing and packaging machinery, as graphite lubricant does not drip or splash like grease, eliminating product contamination risks and meeting food-grade safety and hygiene requirements. In medical equipment and pharmaceutical machinery, the maintenance-free characteristic eliminates contamination risks associated with periodic greasing procedures. In wind turbine main shaft bearings and yaw bearings, where tower-top access is difficult and maintenance costs are extremely high, graphite-plugged bushings significantly reduce lifecycle operation and maintenance expenditures. MYWAY can also incorporate auxiliary components such as molybdenum disulfide or PTFE powder into the graphite formulation upon customer request, further reducing the coefficient of friction or enhancing corrosion resistance.
5. Bronze Rolled Bushings and Wrapped Bushings: Thin-Wall Lightweight Design Saving Radial Installation Space
Bronze rolled bushings (also referred to as wrapped bushings or wall bushings) constitute a major product category developed by MYWAY utilizing metal sheet plastic forming technology. Their defining characteristic is reduced wall thickness, occupying significantly less radial space than cast or forged bushings, making them highly suitable for equipment with compact installation envelopes and stringent weight limitations. These bushings typically feature a multilayer or bilayer structure—a copper alloy layer combined with a steel backing layer (or a single-layer all-copper configuration)—produced through composite rolling processes, then finished through wrapping, sizing, and chamfering operations. Based on different application requirements, bronze rolled bushings can be configured as oil-lubricated types—with lubrication oil grooves, pockets, or holes machined into the copper alloy surface for hydrodynamic or mixed lubrication via external oil supply systems—or as self-lubricating types—with PTFE, graphite, or other solid lubricants applied or rolled into the sliding surface for oil-free or minimal-oil operation.
Flanged wrapped bushings represent a distinctive advantageous product offered by MYWAY, with the flange and sleeve portions integrally formed from the same strip material through a single rolling process, requiring no welding or riveting. The transition radius between flange and sleeve exhibits no stress concentration or material discontinuity defects, enabling simultaneous radial and axial load support, making them highly suitable for industrial robot joints, small gearboxes, and servo motor output shaft support applications. The flange also serves as an axial positioning reference, simplifying assembly depth control during press-fit installation and improving assembly efficiency.
For large-diameter bushing supply, MYWAY possesses flexible production organization capabilities. For non-standard large-diameter wrapped bushings exceeding 150 mm, where conventional die-wrapping methods often become economically prohibitive due to high tooling costs, MYWAY can employ CNC plate rolling machines for single-piece or small-batch custom production, eliminating high tooling expenses for customers while significantly reducing delivery lead times. The material combination options for rolled bushings are extensive—copper layers may utilize tin bronze, phosphor bronze, aluminum bronze, or zinc-copper alloys, backing layers may utilize low-carbon steel or stainless steel, and surface finishes may include tin plating, silver plating, or copper plating to accommodate various corrosive environments and electrical conductivity requirements.
6. Steel-Based Bushings and Powder Metallurgy Bushings: Complementary Solutions for High Load Capacity and High Cost-Effectiveness
Steel-based bushings represent MYWAY’s pure-metal bushing offering for extreme heavy-load and complex stress conditions, with material grades encompassing high-quality carbon structural steels (such as 20# and 45#), alloy structural steels (such as 40Cr and 42CrMo), and austenitic stainless steels (such as 304 and 316L). Compared to copper alloy bushings, steel-based bushings offer yield strength and compressive strength several times higher, with static load capacity reaching up to 250 N/mm² or more, and lower material costs for large dimensions. They are particularly suitable for support rollers in heavy mining machinery, large slewing bearings, metallurgical mill housing window liners, and marine stern tube bearings where loads are extremely high. The machining process primarily involves turning, boring, and grinding operations, with inner bore surfaces typically required to achieve roughness values below Ra 0.8 μm, and assembly grease applied prior to installation to minimize dry friction during start-up. To enhance corrosion resistance, MYWAY can apply surface treatments including zinc plating, nickel plating, chrome plating, black oxide, or phosphating, enabling bushings to maintain extended service life in humid, salt-spray, or mildly acidic environments.
Powder metallurgy bushings (also known as oil-impregnated bearings or sintered metal bushings) represent a highly cost-effective solution offered by MYWAY. The manufacturing process involves: uniformly mixing bronze powder, iron powder, or bronze-iron composite powder with appropriate binders, pressing into green compacts on specialized presses, then subjecting the compacts to high-temperature sintering in controlled-atmosphere furnaces, during which metal particles undergo diffusion bonding to form a porous skeleton with controlled porosity. Following sintering, the compacts are immersed in lubricating oil (typically mineral oil or synthetic oil) under vacuum or heating conditions to fully impregnate the pores. Final sizing or minimal machining achieves the finished dimensions. During operation, relative motion between the shaft and bushing generates heat, causing oil in the pores to expand and migrate to the sliding surface, forming a lubricating film. When equipment stops, oil is drawn back into the pores through capillary action as temperature decreases, achieving a self-priming and self-supplying lubrication effect.
Powder metallurgy bushings typically offer load capacity ranging from 20 to 60 N/mm², suitable for moderate loads and low to medium speeds in operating conditions, including domestic washing machine motor bearings, power tool rotor supports, office equipment (printers and copiers) fuser rollers, automotive wiper motors, and seat adjustment mechanisms. The primary advantages are low cost, suitability for high-volume automated production, exceptional inner diameter consistency eliminating selective assembly requirements. MYWAY offers powder metallurgy bushing materials including bronze-based (copper content above 80%), iron-based (lower cost), and copper-iron composite-based (balancing performance and cost), with oil content controllable within 18% to 25% volume fraction, and lubricating oil viscosity grades selectable per customer specifications.
7. Non-Standard Customization Capabilities and Tooling Inventory: Flexible Response to Diverse Customer Requirements
Bushing applications vary widely, and standard catalog specifications often fail to fully address actual site requirements. MYWAY fully recognizes this reality and has established non-standard customization capabilities as a core service advantage. The technical team can recommend the most suitable material grades, structural configurations, and tolerance fits based on a comprehensive analysis of customer-provided parameters including installation space dimensions, shaft diameter and housing bore size, operational load spectrum, operating temperature range, lubrication method, mating shaft material and hardness, expected service life, and budget constraints. In terms of dimensional specifications, the company can accommodate micro-bushing orders with inner diameters as small as 3 mm, while also possessing the process capability to manufacture large bushings exceeding 500 mm inner diameter, with length ranges spanning from a few millimeters to over 300 mm. Regarding materials, customers may flexibly select from the above-mentioned copper alloys, steel-based materials, stainless steels, composite self-lubricating materials, PTFE, POM, polyimide, and other options, or rely on engineer recommendations.
MYWAY has accumulated over 2,000 sets of precision bushing forming dies covering most internationally standard specifications, meaning customers requiring existing standard sizes can proceed directly to production without additional tooling development costs. For entirely new non-standard dimensions, the R&D team typically conducts a design review with the customer, finalizes sample drawings and process routes, then utilizes the company’s rapid tooling capabilities to complete die manufacturing and sample delivery within a relatively short timeframe. After samples pass customer on-site verification testing, mass production can be rapidly initiated. Notably, for certain collaborative projects—particularly those involving new product co-development in early-stage R&D phases—MYWAY generally waives or partially reduces tooling charges, reflecting the company’s commitment to long-term win-win partnerships with customers.
In terms of delivery responsiveness, leveraging in-house profile casting capabilities, ample strip material inventory, and the 1,900-square-meter finished goods warehouse, MYWAY can achieve 48-hour shipment for standard catalog items, 7 to 15 working days for simple non-standard custom orders, and mutually agreed delivery schedules for complex custom products. Overall lead times significantly undercut industry averages.
