Oilless Braided Composite Self-Lubricated Bearing, Bushing, Steel Backed is a type of bearing that is specifically designed to operate without the need for external lubrication. It consists of a braided composite material, primarily (Polytetrafluoroethylene), which is self-lubricating and able to withstand extreme temperatures and pressures. The steel backing provides structural support and durability, while the composite material ensures smooth, friction-free operation.
This type of bearing is commonly used in applications where lubrication is difficult or impossible, such as in high-temperature or vacuum environments. The self-lubricating properties of the composite allow it to operate effectively without the need for regular maintenance or replacement of lubricants.
The braided composite structure of the bearing also contributes to its durability and wear resistance. The fibers are woven together in a way that creates a strong, yet flexible material that can withstand both compressive and tensile forces. This makes it an excellent choice for applications that require bearings to withstand heavy loads and frequent motion.
Overall, Oilless Braided Composite Self-Lubricated Bearings, Bushings, and Steel Backed products are reliable, efficient, and cost-effective solutions for applications that demand high performance in extreme environments.
Steel Backed Bushing High performance steel reinforced bushings, environmental protection is based on steel substrate, central bronze powder, sintered spherical surface that rolls four ethylene () and a mixture of green polymeric material, bearing rolling and sliding. The product is lead-free environmental protection, the wear-resistant performance is excellent, a plastic layer and a copper layer with high strength, fatigue resistance, impact-resistant performance are a good way to an advantage.

Poly tetra fluoroethylene()
It is a polymer made of tetrafluoroethylene as monomer.White waxy, translucent, good heat and cold resistance, can be used in -180 ~ 260 C for a long time.This material has the characteristics of anti - acid, anti - alkali, anti - various organic solvents, almost insoluble in all solvents.At the same time, has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become easy to clean the ideal coating of the inner layer of the water pipe;Toxic, human carcinogen.

| PROPERTIES | |||
| It works with grease or oil lubrication. All kind of movements are suitable for this sliding material. It has good resistance to dirt, is very robust and has a high load capacity. | |||
| RANGE OF APPLICATION | |||
| truck cranes, agriculture machines, hydraulic cylinders, construction machinery, tale gates | |||
| MAINTENANCE | |||
| It is a low maintanence bearing material with MoS2 sliding layer and lubrication pockets. An initial greasing during installation is necessary, after that, periodic greasing with oil or grease is mandatory. | |||
| MOUNTING ADVISE | |||
| Housing | Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment | ||
| Shaft | Chamfer 5 mm x 15°, for easy insertion of the shaft | ||
| We advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing. | |||
| Gluing | Adhesive should not contact the sliding surface! | ||
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
