Helix Linear Technologies precision torque spline shafts are efficient linear motion devices that offer low-friction motion while transmitting torque. A high-strength composite polymer bushing carries the load between the rotating member (inner race) and the rotating/translating member (bushing). Helix precision torque splines are coated with Helix H10X™ PTFE coating to extend product life and provide an anti-friction surface. The precision torque bushings are offered in both standard freewheeling and anti-backlash designs. These bushings can be mounted using an integral thread, or assembled using a round or compact mounting flange.
