Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations. Cylindrical roller bearings have a high radial load capacity because the rollers and raceway are in linear contact, and they are suitable for applications that provide heavy radial and impact loads.

The rolling element is radial rolling bearing of cylindrical roller. The internal structure of the cylindrical roller bearing is arranged in parallel by rollers, and spacers or spacers are arranged between the rollers to prevent the rollers from tilting or friction between the rollers, thereby effectively preventing an increase in the rotational torque.
