Lead Screws & Ball Screws
|Ball screws incorporate either caged or circulating ball elements to achieve linear motion. They are highly efficient, have predictable life spans and produce minimal heat during prolonged use. They are ideal for long duty cycle and high-speed applications.|
Ball splines allow rolling linear movement of a nut along a central shaft with straight threads or splines. They offer nearly frictionless movement and are capable of performing linear motion while transmitting torque. With high-speed motion and rotation capabilities, they are ideal for applications with an overhang or moment load.
Hybrid ball screw / splines have both helical threads and straight splines for rotational and linear motion on the same shaft. The ball screw and spline nuts have dedicated support bearings directly embedded on their circumferences.
Lead screws use a sliding nut on a shaft with helical grooves. They are compact, quiet, easily reconfigurable for longer or shorter leads and have a high inherent stiffness. They are ideal for vertical or low duty cycle applications.
