This needle roller bearing operates as a stud type track roller with a solid roller stud, fixing thread and mounting aid for installation. The outer ring is particularly thick-walled and runs on a full complement needle roller set, with an outside diameter of 19.0 mm and a width of 32.0 mm. Mass of the unit is 29.0 g. Axial guidance of the outer ring is provided by plastic axial plain washers, a contact flange and a contact washer, without an eccentric collar. Sealing is realized as a three-stage arrangement using plastic axial plain washers (PP) on both sides, keeping contamination out of the raceway without relubrication facility, so the bearing runs on its initial fill for the service life. The assembling aid in the form of a hexagonal socket is located only on the flange side end face, which fixes orientation during mounting and torque transfer through the stud thread.
