Stud mount rollers are permanently bonded to a steel insert with the bearings held in place with snap rings. They are available in neoprene, nitrile and urethane materials and come assembled with a socket head cap screw, spacer and locknut for fast easy mounting.  Hardness ranges from 20 to 95 durometer. These rollers are supplied with standard bearings, precision, or precision-sealed  bearings. Solid, finned and Durasoft styles are all available.

These rollers are also available without the stud and hardware. The roller-only versons are available here.
