Description
This needle roller bearing is built as a stud type track roller with an outside diameter of 30.0 mm and a net mass of 0.087 kg. The design features a particularly thick-walled outer ring running on a needle roller and cage assembly, mounted on a solid roller stud with a fixing thread and a mounting aid for installation. Axial guidance of the outer ring is provided by a contact flange and a contact washer, and the unit does not include an eccentric collar. Sealing on both sides is realized as gap seals (SPSP), which keeps the bearing free-running while limiting the ingress of contaminants without adding contact friction. The thick-walled outer ring together with the contact flange and washer arrangement allows the roller to carry radial loads transmitted through direct track contact, while the stud with fixing thread and mounting aid simplifies alignment and fixation during assembly.
