Product Description

tem NO.: CHB-090

The bearings are wrapped from a cold formed homogeneous bronze(CuSn8 or CuSn6.5),which can achieve exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery.
