Yoke type track rollers   
Yoke type track rollers are single or double row units mounted on shafts or studs. They comprise thick-walled outer rings with a profiled outside surface and needle roller and cage assemblies or full complement needle roller or cylindrical roller sets. Yoke type track rollers can support high radial loads as well as axial loads arising from slight misalignment and skewed running; they are suitable for applications such as cam gears, bed ways and conveying equipment. The bearings are available with and without an inner ring and in both sealed and open versions
Due to a modified material and the optimized raceway geometry of the outer rings for Yoke type track rollers or Stud type track rollers, the basic rating life has been increased by up to 30%.The static and dynamic load carrying capacity has also been increased. At the same time, the stress placed on the mating track has been reduced as a result of the optimised lateral surface profile and its improved surface quality. Due to these measures, highly robust bearing arrangements with an extended operating life can be achieved.
▲   The design’s of all these Yoke Type Track Rollers are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
