Double Row Track Rollers

Double row track rollers offer the same features of a single row track roller with the added benefit of heavy radial, thrust or combined loads.  Yoke-type track rollers are single or double-row units mounted on shafts or studs.  Similar to the single row track roller, we can customize the running surface to meet the specific requirements of the applications.  Cam rollers are similar in their construction to single and double-row support rollers, except that the raceway is formed by a heavy-section roller stud with a fixing thread. The most common running surface profiles can be found on the Special Profiles page under Technical Parameters.
