Amacoil's Model RS4 Drive Nut
Design alternative to screw-based linear drive systems, Model RS4 drive nut provides backlash-free linear motion. The linear pitch is factory-set at one of five different linear pitch settings, determined by application requirements. Pitch wedges between the drive bearings hold them at a specific angle relative to shaft to set linear pitch. Change pitch with a different set of wedges without other components, machinery or controls.
