Eccentric Stud XR Rollers provide a means of precision positioning between the roller and the track or rail surface. This feature allows for adjustment to provide uniform loading amongst mounted rollers.
Roller Body Profiles
Plain XR Rollers
Plain/Cylindrical XR Rollers effectively carry radial loads. For heavy side loads, Plain XR Rollers can be positioned vertically to act as side guides.
Crowned XR Rollers have a spherical body profile and are used to reduce the effects of misalignment by better distributing load over the body and internal bearing elements. Crowned rollers are also used in rotary applications to minimize scrubbing or skidding.
