We provide high-quality, low-noise, long-life, multi category, and multi-purpose bushings.

Self-lubricating multilayer composite bushing

Three-layer composite: steel plate layer, copper powder layer, plastic layer. The steel plate layer plays the role of assembly and positioning, bearing pressure; the copper powder layer plays the role of connecting the plastic and auxiliary friction reduction; the plastic layer plays the role of wear-resistant and self-lubricating. Its advantage is that it can be self-lubricating when there is no oil, low noise when working, thin-wall design structure with small volume, and wear-resistant can keep long-term non-wear. It is a new type of bearing to replace needle roller bearings, oil bearing and copper alloy bearings. The advantages of this series of bearings of our company are the use of high-end equipment in the production process, strong automatic production capacity, small wall thickness tolerance, high precision, advanced product formulation technology, and according to the customer’s personalized needs, simulation tests of working conditions. The product quality and development technology are at the international advanced and domestic leading level.

Boundary lubricating bushing

The steel plate layer plays the role of assembly and positioning, bearing pressure; the copper powder layer plays the role of connecting the plastic and auxiliary friction reduction; the plastic layer plays the role of wear-resistant and self-lubricating. Its advantage is that it can be self-lubricating when there is no oil, low noise when working, thin-wall design structure with small volume, and wear-resistant can keep long-term non-wear. 

More suitable for heavy-duty and low-speed applications, such as metallurgy, engineering machinery, water conservancy and hydraulic engineering.
This is because its material is a benign boundary lubricating material, particularly suitable for rotation under high load and low speed
Motion, swing motion, conditions, and needs determine.

Bimetal bushing

Bimetallic bushing bearing is a type of oil-free lubrication bearing, which is made of high-quality low-carbon steel (SPCC, SPHC, etc.) as the substrate, and is surface sintered with lead tin bronze alloy (CuPb10Sn10 or CuSnZn6Pb3). After multiple high-temperature sintering and dense rolling, it is formed into a bimetallic strip of copper and steel. The copper alloy surface can be processed with various types of oil grooves and holes according to the needs of use, suitable for situations where continuous or difficult refueling is not possible..
The application range of bimetallic bushing bearings is wide, which can be used for balance bridge bushings, gaskets, automotive steel plate bushings, internal combustion engine main shaft bushings, connecting rod bushings, rocker arm bushings, oil pump side friction plates, small and medium power internal combustion engine bushings, train engine bushings, air pressure machine bushings, refrigerators, etc. in heavy-duty vehicles. In summary, bimetallic sleeve bearings are a type of high load, low-speed motion bearing that exhibits particularly good self-lubricating performance in the absence of lubricating media.

Solid lubricating bushing

Three-layer composite: steel plate layer, copper powder layer, plastic layer. The steel plate layer plays the role of assembly and positioning, bearing pressure; the copper powder layer plays the role of connecting the plastic and auxiliary friction reduction; the plastic layer plays the role of wear-resistant and self-lubricating.

Wrapped bronze bushing

Wrapped Bronze Bushing are mainly made of copper alloy substrates, such as tin bronze alloys (ZCuSn10Pb1, ZCuSn10Pb5, ZCuPb10Sn10, ZCuPb15Sn8) or zinc copper alloys (ZCuZn38Mn2Pb2). These materials have different characteristics and are suitable for different working conditions. During the manufacturing process, the copper plate is first rolled, and then the copper sleeve is shaped to ensure that its size and shape meet the design requirements.
The working surface of Wrapped Bronze Bushing is usually covered with regular diamond shaped oil holes, which serve to store oil and help establish an oil film in the early stages of movement, thereby reducing the friction coefficient. In addition, the cost of Wrapped Bronze Bushing is lower compared to machine-made copper sleeves and rolling bearings, as it can more efficiently utilize copper materials and is lighter in weight. Wrapped Bronze Bushing are widely used in various medium and low-speed applications, especially in fields such as agricultural machinery, construction machinery, and engineering machinery. They also exhibit good wear resistance and corrosion resistance in high load and high-speed sliding environments.

Metallic SelfLubricating Bushing

JDB bushing is a special type of bearing, mainly embedded with graphite or molybdenum disulfide solid lubricant on the substrate of various raw materials such as high-strength brass (CuZn24A16), tin phosphorus bronze (CuSn8P3), bearing steel (GCr15), gray iron (HT250), etc. This type of bushing breaks through the limitations of general bearings relying on oil film lubrication, and can work normally in an oil-free state, protecting the shaft from wear while exhibiting solid lubrication characteristics.
The characteristic of JDB bushing lies in its self-lubricating performance. It is made by opening appropriately sized and orderly arranged holes on the metal friction surface of a high-strength brass substrate, and then embedding a molded solid lubricant with unique self-lubricating properties into the holes. This type of bearing combines the advantages of metal matrix and special formulated lubricating materials, and can still be used normally in a low oil or oil-free state.Its hardness is twice as high as that of ordinary copper sleeves, and its wear resistance is also twice as high, so it performs well in these high load situations
