In cylindrical roller bearings, the roller is a very critical component. Its geometric structure, the so-called logarithmic profile, can distribute the stress in the best way when bearing the load. Its surface treatment can optimize the formation of oil film and the movement of rollers, and improve the reliability of operation and the ability to withstand angle errors. Cylindrical roller bearings with cages can withstand heavy radial loads and high speeds, while full cylindrical roller bearings are suitable for bearing very heavy radial loads and medium speeds.
