Bronze Wrapped Components

Bronze Wrapped Components

The bearings are wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are formed with diamond shaped lubrication indents in the bearing surface. The indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. These materials are suitable for construction and agricultural machinery applications.
