Composite plain (cylindrical) bearings made of POM are suitable for oscillating, rotating, and linear motions and can absorb radial loads. After initial lubrication, they are optimized for minimal maintenance in demanding operating conditions. The pockets in the sliding surface serve as grease reservoirs. Lubrication can significantly extend the lifespan of the bearings. Despite their compact design, they can withstand high loads. Straight (cylindrical) bearings with wound fibers are also suitable for oscillating, rotating, and linear motions and can absorb radial loads.
