The bearings are wrapped from a cold formed homogenous bronze(CuSn8)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 lubri-cant 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 agricultutal machinery etc.where high load and slow movement occur.
