Product Description

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. Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used. 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.
