High Load Bimetallic Self-lubricating Bushings CuPb24Sn4 & CuPb30 Material
1. Product Description
High Load Bimetallic Self-lubricating Bushings CuPb24Sn4 & CuPb30 Material are backed with high quality carbon steel with bronze alloy sintered of the specification CuPb30 or CuPb24Sn4,it's alloy surface can be machined with ball shaped oil pockets for easier oil storage.This structure, whose mechanical strength is high, can be used under lubricated conditions and high-speed/high-load operation. It can be made from a variety of different materials, depending on the application, use conditions and lubrication.
