Convert the rotary motion of a smooth shaft into linear movement. Often used with conveyors and other equipment that already have a rotating shaft, these drive nuts move loads such as carriages and scanning sensors or cameras in a straight line. Internal friction rollers contact the shaft at an angle to create motion. The bearings are lubricated for life, so the drive nuts require little maintenance. Thrust adjustment bolts let you fine-tune the amount of force the drive nuts exert. If the load becomes too heavy or something blocks the motion, the drive nuts will slip along the shaft instead of damaging your equipment. You can push a load with these drive nuts or mount them to the top of a load to carry it.

A lead screw that converts rotational motion to linear motion sits inside the motor body for a compact footprint. Add a driver and controller to these actuators to repeatedly position loads with speed and precision. Moving in small, equal steps, these actuators are good for jobs requiring fine motion control, such as positioning electrical components on a circuit board. Their load stays in position even when a counteracting force is applied, so you don’t need encoders, sensors, or other position feedback devices.

Dynamic load capacity is the maximum load an actuator can move. If you increase the speed, the dynamic load capacity decreases. Click on a part number and select "Product Detail" to view the load-speed chart and confirm the actuator will work for your application.
