The main advantages of the Uhing® rolling ring principle are:

• Highest efficiency: Gear and payload are fully supported by roller bearings.
• Automatic traversing movement.
• Variable traversing speeds (0 m/s to 4.2 m/s); separately set for both directions with constant shaft rotation.
• Adjustable traversing width and position.
• High dynamics at points of reversal.
• Can be released from the shaft.
• Low operating costs.
• Low maintenance requirements.
• Operate like nuts on a screw rod with adjustable right-handed or left-handed pitch (can equal zero).
• Achieved via pivoted Uhing® rolling rings mounted on roller bearings, with a specially shaped running surface pressed against the rotating shaft.
• Roller lever contact with cams along the stroke path allows for complex motion patterns.
