With the Uhing model RG rolling ring linear drive, changes to travel direction and linear speed are both adjustable regardless of the rotational direction or speed of the drive motor. This purely mechanical control over travel direction and linear speed makes it easier to meet application requirements when compared to systems that require designing-in clutches, brakes, gearboxes, servo motors and complex control systems. It also minimizes operating and maintenance costs. And because rolling ring systems operate continuously even when changing direction or pitch, production rates and throughput improves.
