Yoke 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. Yoke type roller bearing track rollers are mounted on a shaft or stud. They are not mounted in a housing bore but supported on a flat raceway (mating track). Yoke type roller bearing track rollers are available with or without an inner ring. They are produced with or without axial guidance of the outer ring. Yoke type roller bearing track rollers are open or sealed on both sides.
