Cylindrical roller bearings are commonly separable and easy to mount and dismount. They can be divided into single row, double row and multi-row cylindrical roller bearings. The widely used bearings are cylindrical roller bearings with cage. There are single or double row bearings with a full complement of rollers and other bearing arrangements. Cylindrical roller bearings have high radial load carrying capacity and are also suitable for high speeds.
