This needle roller bearing, KR35-B, is a stud type track roller with a single row needle roller and cage assembly running inside a particularly thick-walled outer ring. The outer ring outside diameter is 35.0 mm and the unit weighs 0.163 kg net. Axial guidance of the outer ring is achieved through a contact flange and contact washer, while the solid roller stud incorporates a fixing thread and a mounting aid for straightforward installation. The design has no eccentric collar. Sealing on both sides (SPSP) keeps contaminants out of the running track while retaining lubricant, allowing the roller to operate with consistent rolling contact along its outer ring surface. The thick-walled outer ring combined with the solid stud construction gives the assembly rigidity suited to guiding loads along a fixed track, with the contact flange and washer arrangement handling axial positioning without relying on a separate housing.
