German EPRATAL bearings EPRATAL models EPRATAL prices

EPRATAL bearings are precision mechanical components that convert sliding friction between the rotating shaft and the bearing housing into rolling friction, thereby reducing frictional losses. Rolling bearings generally consist of four parts: inner ring, outer ring, rolling elements, and cage. The inner ring fits with the shaft and rotates with it; the outer ring fits with the bearing housing to provide support; the rolling elements are evenly distributed between the inner and outer rings by the cage, and their shape, size, and quantity directly affect the performance and service life of the rolling bearing; the cage ensures uniform distribution of the rolling elements.
