Rolling Ring Drives / Traverse units are suitable for any application requiring linear reciprocating motion with constant speed and unidirectional rotation of a shaft

The Rollring traverse drive perform similar to a lead screw but has added advantages of automatic and instantaneous reversal, finely variable linear speed by flick of a lever, finely variable stroke length etc, without varying the speed and direction of rotation of the shaft.

This is a unique method for converting rotary motion into linear reciprocating motion on the principle that contact pressure created between a correctly dimensioned rolling rings and shaft enables significant forces to be transmitted. The linear speed is directly related to the angle of contact between rolling rings and shaft.
