RG4-20-2 Linear Drive

RG4-20-2 Linear Drive

Amacoil/Uhing model RG4-20-2 rolling ring drives meet application requirements for a wide range of medium to heavy duty applications. Featuring an aluminum housing, model RG drives have been used in factory settings for over a half century to provide reciprocating linear motion in spooling equipment, spraying machines, scanners, grinders and other automated machinery requiring a linear motion component.

RG4-20 models have four rolling ring bearings inside providing a thrust of 72 pounds. Factory tested for twelve million reversal cycles, RG drives are durable and reliable. The drives offer automatic, mechanical reversal. Travel direction and linear pitch are controllable independently of the drive motor thus eliminating the need for electronic controls and programming. Numerous options offer added linear motion control.
