Stud type track rollers   
Stud type track rollers are similar in their construction to single and double row yoke type track rollers, except that the raceway is formed by a heavy-section roller stud with a fixing thread and lubrication hole. Due to the thick-walled outer ring with profiled outside surface and the rolling element set, they 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. 
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 Stud 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.
