Product Spotlight: Linear Drive

The Model RG80 linear drive supplies up to 800 lb of side thrust for heavy load linear-motion applications.

Rolling-ring linear-motion engineering permits mechanical control over reversal, eliminating the need for electronic controls and a reversible motor. Linear pitch (speed) can be manually adjusted without gear reduction or adjusting drive motor speed.

The RG80 is a friction drive that runs on a case-hardened and ground shaft. Drive speed and travel direction are determined by the angle of the specially contoured rolling-ring bearings relative to the drive shaft. At the stroke’s end the drive contacts an end stop that pivots the rolling-ring bearings to reverse travel direction. The drive motor continues to rotate in one direction and no gear changes or other control adjustments are required.
