The rolling elements are rollers with high load capacity. The rollers are guided by the ribs of the inner ring or the outer ring. The inner and outer rings can be separated, so the installation is simple, and the inner and outer rings can be installed with interference fit. In addition, both the inner and outer rings have no ribs, which can move freely in the axial direction. Therefore, it is widely used as a "free end bearing" to absorb shaft expansion. For designs with ribs, the roller end face and the ribs can bear a slight axial load. HT cylindrical roller bearings have improved the ability to withstand axial loads by optimizing the shape of the roller end surface and the design of the rib shape. The internal special design of E-type cylindrical roller bearing improves the radial load capacity. E-type small diameter bearings have become a standard design.
