Wear-resistant copper axle bush

Category: Copper bearing bush




Wear-resistant copper axle bush, environmental protection recoverable copper axle bush. Using excellent electrolytic copper as matrix, tin ingot and lead ingot are mixed according to the national standard proportion to form high wear-resistant self-lubricating copper alloy material. In the absence of lubricants and water lubricants, it exhibits excellent sliding and self-lubricating properties. Under the load of high-speed rotation and rocking motion, the impact load is up to40MPaIt shows excellent flexibility and is the first choice for medium and low speed operation machinery.
