Radial needle roller cage assemblies

The radial needle roller and cage assembly is a one- or two-row assembly consisting of cages and needle rollers. The single-row design is based on DIN 5 405-1. Since their radial height only corresponds to the diameter of the needle rollers, radial needle roller and cage assemblies enable bearings with the smallest radial space. They are very stable, suitable for high speeds and particularly easy to assemble. Bearings with a high level of concentricity are achieved if the raceways are designed with precise form. The radial internal clearance can be influenced by the type of needle roller and the shaft and housing tolerance. Radial needle roller and cage assemblies require that the raceway on the shaft and in the housing is hardened and ground. Two-row radial needle roller and cage assemblies are only available in certain enveloping circle diameters FW. They are marked with the suffix ZW. The radial needle roller and cage assembly with plastic cage can be used at operating temperatures from -20 °C to +120 °C. The radial needle roller and cage assembly is available with a plastic and sheet steel cage. Plastic cages have the suffix TV and are only available in certain sizes.
