The roller of cylindrical roller bearing is in linear contact with the raceway surface, the radial load capacity is large, and the roller is guided by the guard edge of the inner ring or the outer ring, so it is also suitable for high-speed rotation from the perspective of structure. The rolling element is a roller with high load capacity. 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, the inner and outer rings have types without guards, and can move freely along the axis, so it is widely used as a "free end bearing" to absorb shaft expansion. For designs with guards, small axial loads can be borne between the roller end face and the guard. The number of roller columns can be divided into single columns, double columns, four columns and other forms. In order to meet special uses such as heavy loads, there are also non-separable SL full-loaded roller bearings. HT cylindrical roller bearing improves its ability to bear axial load by optimizing the design of roller end face shape and rib shape. The special internal design of the E-type cylindrical roller bearing improves the radial load capacity. E-type trail bearings have become standard designs.
