Features
Yoke and stud type roller bearing track rollers:
· 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.
