Guides motion along a fixed track through a stud-mounted outer ring supported by a full complement of cylindrical rollers arranged in double row. The outside diameter is 40.0 mm, width 58.0 mm, and net mass 0.239 kg. The outer ring has a particularly thick wall and is guided axially by the rolling elements themselves, without an eccentric collar. Sealing is provided on both sides by labyrinth seals, coded 2LB. The solid roller stud includes a fixing thread and a mounting aid for straightforward installation. The double row full complement roller set gives the outer ring a high load-carrying cross-section relative to its diameter, while axial guidance coming directly from the rolling elements keeps the design compact without a separate guiding collar. The labyrinth seals on both sides restrict ingress of contaminants while allowing the outer ring to rotate against the track surface. The fixing thread on the stud allows direct bolted mounting into a housing bore, with the mounting aid simplifying alignment during assembly.
