Needle Roller Bearing-With Inner Ring

Each features hardened steel construction, which helps to offer long service life. They are also suitable for use where needle roller bearings must be combined with wider inner rings in order to allow larger axial shaft displacement in relation to housing. The optimum running surfaces are required for seal lips.Needle roller bearing components SKF supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components. Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground.This self aligning radial needle roller bearing has an inner ring and a steel cage, and is suitable for applications with high dynamic and static loads. It has a spherical outer ring and a concave plastic support ring, which allow the bearing to compensate for static misalignments of up to 3 degrees between the shaft and housing.


Inner rings are made from hardened rolling bearing steel and have precision machined or ground raceways. They are used where: The shaft cannot be used as a raceway with needle roller and cage assemblies, drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed end and needle roller bearings.
