Product Specification

The  30mm self-lubricating bearing with sintered bronze is a high-performance bearing designed for applications requiring superior wear resistance and low friction. The sintered bronze base material offers excellent strength and durability, while the (Polytetrafluoroethylene) coating provides self-lubricating properties that eliminate the need for external lubrication. This combination results in a bearing that can operate smoothly and reliably over extended periods of time, even in harsh environments.

The 30mm diameter of this bearing makes it suitable for a wide range of applications, including machinery, equipment, and other industrial uses. The sintered bronze construction ensures that the bearing can withstand heavy loads and high speeds, while the coating reduces friction and wear, extending the bearing's lifespan.

Overall, the  30mm self-lubricating bearing with sintered bronze is a reliable and efficient choice for applications requiring superior wear resistance and low friction.

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.

Other: marine and offshore equipment, other applications in water or in outdoor environments

Bronze Backed Bushing Typical Applications

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.
