The Kerk® RGS – Rapid Guide Screw – is a screw-driven linear slide that offers exceptional linear speed, accurate positioning, and long life in a compact, value-priced assembly. The length and speed of the Kerk RGS is not limited by critical screw speed, allowing high RPM and linear speeds, even over long spans.
Standard leads include .100", .200", .500" and 1.00" (2.54, 5.08, 12.7 and 25.4 mm) travel per revolution. Many optional leads, both inch and metric based, offer everything from high efficiency to non-backdriving leads for vertical applications, eliminating the need for brakes. With Kerk's wide range of available leads, speeds of more than 60 inches per second (1.5 meters per second) are possible, rivaling belts and cables while offering superior positioning accuracy, repeatibility and axial stiffness.
The Kerk RGS slide includes a precision aluminum guide and carriage and is driven by a precision rolled stainless steel lead screw. The moving surfaces include Kerkite® high performance polymers running on Kerkote™ TFE coating.
The Kerk RGS has a unique, compact profile that provides exceptional torsional stiffness and stability for its size and weight. The integral mounting base allows support over the entire length if desired. Lengths up to 8 feet (2.4 meters) can readily be built, and longer lengths are possible on a special order basis.
The Kerk RGS comes standard with a wear-compensating, anti-backlash driven carriage. Additional driven or passive carriages can be added, along with applications specific customization. Linear guides, without the drive screw, are also available.
Kerk RGS® Linear Slides for motor and sensor mounting – Now available, the RGSW and RGSWX Series configurations of the RGS Linear Slide simplify motor and limit switch sensor mounting. Both versions include slots for sensor brackets and mounting provisions for a flag on the carriage, while the RGSWX also includes a bracket for motor mounting. The motor, coupling and sensors are not provided, but a sensor mounting kit for a common optical sensor is available from Kerk (see Sensor Mount Kit).
