Description

This cylindrical roller bearing guides and supports rolling loads through a double row of full complement cylindrical rollers running against a particularly thick-walled outer ring. The outer ring is guided axially by the rolling elements, and the unit is built on a solid roller stud with a fixing thread and a mounting aid, simplifying installation without the need for a separate housing. Outside diameter is 72.0 mm, width is 80.0 mm, and net mass is 0.986 kg. There is no eccentric collar on this version. Sealing is provided on both sides by labyrinth seals (2LB), keeping contamination out of the roller path while allowing the outer ring to rotate freely under load. The full complement roller set increases the number of load-carrying elements in contact, which raises the load capacity of the design compared to a caged arrangement of the same size. The thick-walled outer ring and stud-mounted design make this bearing suitable for direct mounting where axial guidance is taken up by the rolling elements themselves, without additional axial guiding components.
