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 Specifications Roller diameter (mm): 40 Roller width (mm): 20 Roller length (mm): 58 Stud diameter (mm): 22 Thread length (mm): 19 Thread size: M18x1.5 With sealing: Yes Punch shape: Internal hexagon O.
