STRUSTURE
Wrapped dry sliding bearings also have a multi-layered composition. A
porous bronze layer is sintered onto a steel or bronze strip. The function
of this layer is to connect the carrier and the sliding layer. It also ensures
that the necessary heat removal can occur.
The bearings are wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in 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 applications.
