BR3E bimetal solid lubrication bushing
BR3E Solid lubrication bearing is a new thin wall solid lubrication bearing, which is made of BR3A bimetallic material as the base and special solid lubricant embedded in the alloy layer. The alloy material with high strength and load bearing is used as the matrix, and the ideal filling material is wear-resistant. The reasonable diamond block lubrication design has a lubrication area of more than 25%, so it can play a good role in lubrication and wear resistance.
The products have been used in automobile gearboxes, generators, elevators, cranes, metallurgical machinery and other industries.
