Traverse Units

Rollring Traverse units are linear drives, which converts constant speed rotation of a plain round shaft into variable speed, variable stroke, automatic reciprocating motion without changing the direction rotation of shaft. Used in any application where a constant speed rotation of a shaft needs to be converted to automatic reciprocating motion with instantaneous reversal, Infinitely variable linear speed and variable stroke length.

This is a unique method of converting rotary motion into linear reciprocating motion on the principle that contact pressure created between a correctly dimensioned ring and shaft enables significant forces to be transmitted. The linear speed directly related to the angle of contact between the ring and shaft.
The Reversal is automatic and instantaneous. Linear speed (Traverse Pitch) is very finely variable by flick of a lever on the dial. Traverse stroke length infinitely variable along the length and is limited only by the shaft length.
