The flanged copper cylindrical polymer plain bearings with tin plating are a type of high-performance bearing designed for various industrial applications. These bearings feature a copper alloy base with a polymeric lining, providing excellent wear resistance and low friction properties. The flanged design adds stability and rigidity, ensuring a secure fit within the housing. The tin plating further enhances corrosion resistance and durability, making these bearings suitable for use in harsh environments. Wh used in machinery, automotive components, or other industrial settings, these bearings offer reliable performance and extended service life.

Bushings, or plain bearings, operate with sliding motion between the moving surfaces. Bushings are selected based on the rotating speed and the applied load. Most bushings do not require additional lubrication to operate.
Self-lubricating bronze composite bushings consist of a layer sintered on a brown strip. These bushings are corrosion resistant and suitable for high temperature applications that can be made without the use of oil requiring long duty cycles.
This type of self-lubricating bearing is used in the radial or axial direction, especially in the steel and cement industries. Self-lubricating -bronze composite bushings can be used in panels as bridge supports, since the thick sliding layer on the inner surface can withstand loads of up to 140 N / mm².
1. / Pb 0.01 ~ 0.03mm mixture, provides an excellent initial transfer film, which effectively covers the contact surface of the socket assembly, forming an oxide type solid lubricant film.
2. sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bushing surface, also serves as a reservoir for the -lead mixture.
3. Bronze bracket, gives exceptionally high load capacity, excellent heat dissipation. Have very good corrosion resistance.

* Depending on operating conditions
This type of bearing is used radially or axially, particularly in the steel and cement industries.
Industrial: aerospace, agricultural equipment, construction equipment, material handling equipment, forming machines - metal, plastic and rubber; office equipment, medical and scientific equipment, packaging equipment, pneumatic and hydraulic equipment cylinders, pumps and motors, railways and tramways, textile machines, valves, etc.
Other: marine and offshore equipment, other applications in water or in outdoor environments
It can meet the demanding criteria of long life and trouble-free performance with or without lubricant, especially for high chemical resistance requirements.
The Bronze Backed bushing is widely used in steel metallurgy in applications such as roller groove bushings of later casting machines, concrete injection pumps and screw conveyors for concrete. They can also be made of steel housings or be transformed into flanged bushings that can move in both radial and axial directions.
The Bronze Backed bushing is particularly suitable for high temperature environments where no oil is efficient and the machine must operate under consecutive long term conditions.
