This cylindrical roller bearing works as a stud type track roller, running directly on a mating track surface without a separate shaft. It carries a double row of full complement cylindrical rollers set inside a particularly thick-walled outer ring, with the outer ring guided axially by the rolling elements themselves. The solid roller stud has a fixing thread and a mounting aid, and an eccentric collar allows adjustment of the roller position relative to the mounting surface. Outside diameter is 62.0 mm, width is 80.0 mm, and net mass is 0.782 kg. Sealing type 2LB consists of labyrinth seals fitted on both sides, protecting the full complement roller set from contamination while keeping friction low since no contact seal lips are used. The thick-walled outer ring combined with the full complement roller arrangement gives high radial load capacity in a compact cross-section, and the axial guidance through the rolling elements removes the need for separate axial location. The fixing thread on the stud together with the mounting aid simplifies alignment during installation, and the eccentric collar permits fine positioning against the track once the roller is fixed in place.
