This stud type track roller guides linear motion along a mating rail through a double row cylindrical roller bearing set with a full complement of rollers and a particularly thick-walled outer ring featuring a central rib. The outer ring is guided axially by this rib together with the rolling elements. The unit is built in X-life design without an eccentric collar, with a solid stud incorporating a fixing thread and a mounting aid. Outside diameter is 62.0 mm, width is 80.0 mm, net mass is 0.75 kg, sealing type is 2RS. The full complement roller arrangement and thick-walled outer ring support high radial load capacity within the given envelope, while the central rib provides built-in axial guidance of the outer ring without extra components. Protected lip seals on both sides shield the roller and rib contact surfaces from contamination, maintaining consistent rolling behaviour along the track. The fixing thread and mounting aid simplify stud installation and secure axial positioning during assembly.
