Overview
Technical Parameter
Steel copper alloy products with low-carbon steel plate as the matrix material and CuPb10Sn10 or CuSn6Zn6Pb3 materials sintered on the surface. This product has the strongest load-bearing capacity among dual alloy bearings, and is used in the balance axle bushings of heavy-duty vehicles. It is a widely used high load low-speed motion bearing.
