Cylindrical Roller Bearings RN319M Single Row RN319 M for Water Pump 502319H

The internal structure of cylindrical roller bearings adopts parallel arrangement of rollers, with spacers or isolation blocks installed between the rollers to prevent tilting or friction between the rollers, effectively preventing an increase in rotational torque.
The cylindrical roller is in linear contact with the raceway and has a high radial load capacity. Suitable for withstanding heavy loads and impact loads, as well as high-speed rotation.
The raceway and rolling elements of cylindrical roller bearings have geometric shapes. After improved design, it has a high load-bearing capacity. The new structural design of the retaining edge and roller end face not only enhances the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the retaining edge, thereby improving the performance of the bearing.
