Linear plain bearings and plastic linear bearings

Linear plain bearings are linear locating bearing unlimited stroke length. These linear guidance systems Miniature plain guidance system may be, Permaglide linear plain bearings and Permaglide linear plain bearing units as well as flat guidance system. Plastic linear bearing is a self-lubricating properties of linear motion system, the biggest difference is the metal with the metal linear bearings linear bearing is rolling friction, is the point of contact between the bearing and the cylinder axis, so this is suitable for low load speed movement; and plastic linear bearings are sliding friction, it is surface contact between the bearing and the cylinder axis, so this for high-load low-speed movement.
