Needle roller/axial ball bearing PWKR80-2RS-XL INA

Description

Cam rollers Stud type roller bearing track rollers are ready-to-fit needle or cylindrical roller bearings of single or double row design. They have particularly thick-walled outer rings with a crowned outside surface (also available with a cylindrical outside surface on request), can support high radial loads and tolerate axial loads which are due to small misalignments, skewed running or temporary contact running impacts. Instead of an inner ring, stud type roller bearing track rollers are supplied with a heavy-section roller stud with fixing thread and a mounting aid. They are not mounted in a housing bore but supported on a flat raceway (mating track). In the design with an eccentric collar, stud type roller bearing track rollers can be adjusted to the mating track. As a result, larger manufacturing tolerances can be tolerated, for example, in the adjacent construction. Stud type roller bearing track rollers are always produced with axial guidance of the outer ring. They are open or sealed on both sides.
