Ina Needle roller and cage assembly K100-108-27 Inner Ø 100 mm Outer Ø 108 mm Width27 mm

Needle roller assemblies according to DIN 5405-1/ISO 3030 are single or double-row units consisting of cages and needle rollers. The single-row version is based on DIN 5405-1. Since their radial height corresponds only to the diameter of the needle rollers, needle roller assemblies allow for bearings with minimal radial space requirements. They are highly load-bearing, suitable for high speeds, and particularly easy to assemble. With precisely shaped raceways, bearings achieve high roundness accuracy. The radial clearance can be influenced by the type of needle rollers as well as the tolerances of the shaft and housing. Needle roller assemblies require that the raceway on the shaft and in the housing is hardened and ground. Double-row needle roller assemblies are only available in certain outer diameters and are marked with the designation ZW.
