应用特点：
JF-800 bimetallic bearing is a steel copper alloy product made of low-carbon steel plate as the matrix material and sintered with CuPb10Sn10 or CuSn6Zn6Pb3 material on the surface. This product is 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 and low speed motion bearing.
