MYWAY Bushings for Every Part of Your Excavators
Technological Advances in Bushing Systems for Tracked Equipment Undercarriages
As a critical wear component in tracked equipment undercarriages, bushing innovation directly impacts service life and maintenance costs. Current industry advancements primarily focus on three core directions:
1. Sealed Lubrication System Innovations
Modern sealed and lubricated track systems establish a continuous oil film between the pins and bushings, significantly reducing wear. Industry leaders like Caterpillar employ proprietary sealing technology and synthetic lubricants, reducing friction at sealing interfaces by up to 50%. Synthetic oils not only minimize adhesion between seals and bushings but also resist breakdown, maintaining high lubrication quality over extended periods and effectively extending bushing service life.
2. Breakthroughs in Surface Treatment Technologies
John Deere’s SC-2 coating technology fuses a specialized coating onto the bushing surface at temperatures exceeding 2000°C, achieving a hardness more than three times that of conventional hardened steel. This innovation can double bushing lifespan and, under certain conditions, eliminate the need for bushing rotation maintenance entirely.
3. Structural Design Innovations
Komatsu’s rotating bushing solutions include:
A parallel-link undercarriage system for small and medium equipment, allowing bushings to rotate freely during sprocket engagement.
A dual-bushing link assembly for large equipment, which adds a rotating bushing to the traditional fixed bushing design.
Similarly, Case’s Max-Life system incorporates a hardened rotating bushing that covers the fixed bushing, achieving up to twice the lifespan of standard systems under specific conditions.
These technological advances have fundamentally transformed maintenance practices for modern undercarriage systems, significantly reducing the need for traditional bushing rotation. Caterpillar’s System One further optimizes bushing compatibility with the entire undercarriage through self-contained pin-and-bushing assemblies and a center-track idler design, enabling uniform wear and long-term reliable operation.
Bushing Solutions for Excavator Undercarriage Systems
In excavator undercarriage systems, components such as track rollers, idlers, and track links are critical friction points, demanding exceptional wear resistance, load capacity, and impact resistance. The table below summarizes commonly used bushing types, industry references, and MYWAY’s corresponding solutions:
| Component | Core Requirements & Operating Conditions | Common Bushing Types & Industry References | MYWAY Solution |
|---|---|---|---|
| 🛞 Track Rollers | Supports machine weight and withstands heavy impact loads; requires high wear resistance and lubrication. Standard JB/T 2985-2001 outlines technical requirements, emphasizing high hardenability, toughness, wear resistance, and lubrication. | Bimetal bushings are widely used (e.g., brands like “Tengong” offer such products). Hardened steel bushings (e.g., 45# steel, 40Cr) are also common. | MYWAY Bimetal Bushings, offering excellent wear resistance suitable for high-load and intermittent heavy-duty conditions. |
| ⛓️ Idlers | Supports track rails and limits sag; relatively lower loads but requires reliable wear resistance. May use floating seal structures with bushings. | Bimetal or bronze bushings, depending on load conditions. | MYWAY Bimetal or Bronze Bushings, providing stable low-friction and maintenance-free operation. |
| 🔗 Track Links | Forms track joints with pins; directly subjected to wear and impact, requiring extreme wear and compressive strength. | Pin bushings, often made of powder metallurgy (e.g., iron-copper-carbon systems) or bimetal materials for high wear resistance. | MYWAY Powder Metallurgy Bushings or Bimetal Bushings, delivering high compressive strength and wear resistance. |
