Cylindrical roller bearings contain high radial-load capacity and moderate thrust loads. They contain rollers, which are cylindrically shaped, but are not true cylinders. These 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 roller and other bearing arrangements. Cylindrical roller bearings have high radial load carrying capacity and are also suitable for high speeds.
