Are ready-to-fit needle or cylindrical roller bearings of single or double row design Are mounted on shafts or studs (yoke type track rollers) or supplied with a heavy-section roller stud with fixing thread and a mounting aid (stud type track rollers) Have particularly thick-walled outer rings with a crowned outside surface can support high radial loads Tolerate axial loads which are due to small misalignment defects, skewed running or temporary contact running impacts Are available with or without an inner ring (yoke type track rollers) Are produced with or without axial guidance of the outer ring (stud type track rollers are always produced with axial guidance) Are open or sealed on both sides Are not mounted in a housing bore, but are supported on a flat mating track Can be adjusted to the mating track in the design with the eccentric collar, thus permitting, for example, larger manufacturing tolerances in the adjacent construction
