This type of bushing is widely applied in hoisting machines and other construction machines, automobiles,tractors, trucks, machines tools and some mineral engines. It can be fabricated into bushes, half bearings, flanged bushes, thrust washers, spherical bearing and so on.
The bearings are wrapped from a cold formed homogeneous bronze (CuSn6.5P/CuSn8P) with exceptional material properties.
The standard sizes incorporate holes, which are dispersed in a special way over the whole bearing surface.
These holes 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 etc. where high load and slow movement occur.
