Rolling Ring Linear Drives for Reciprocating Motion Control Applications
Our rolling ring drives simplify set-up and operation by eliminating the need for complex controls and programming. Linear motion speed and travel direction are mechanically controlled independently of the drive motor. Example applications: winding machines, spray & coating equipment, scanning devices, other applications requiring repetitive "back-and-forth" linear motion.
Our rolling ring drives convert the rotary motion of a threadless shaft into backlash-free linear motion output. The absence of threads means there is no clogging or jamming. If the system is somehow overloaded, the shaft simply slips instead of churning and grinding. (See How it Works)
Special machining and compression of the rolling ring bearing assembly prevent backlash, and make it unnecessary to design-in, or purchase, extra anti-backlash solutions such as preloaded nuts, shims or double enveloping gears. There is never any "play" between shaft and bearing. Rotary motion input from the shaft is therefore immediately converted into linear motion output with no backlash including during reversal of the system.
