Stepper Motors with Linear Actuation
Instead of a shaft, these stepper motors have a lead screw that converts rotational motion to linear motion. Moving in increments smaller than the thickness of a sheet of paper, they're ideal for applications that require fine motion control, such as positioning electrical components on a circuit board. They move in equal steps and hold their position when stationary, so they do not require encoders, sensors, or other position feedback devices. The lead screw is built into the motor, so there are fewer points of failure than systems that use a shaft coupling to connect the lead screw. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
External lead screw stepper motors work similar to a traditional linear motion system; attach the load to the flanged nut, which travels back and forth along the lead screw.
Pass-through lead screw stepper motors give you the most design versatility because there are two ways to move your load: on the motor body or on the ends of the lead screw. The motor moves when the lead screw is fixed or the lead screw moves when the motor body is fixed.
Travel distance per full step determines the control you have over the motor’s positioning. The smaller the measurement, the finer positioning control you have, but the more steps it will take to go the same distance.
Dynamic load capacity is the maximum load a motor 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 motor will work for your application.
All motors require a driver and controller (not included).

Compact Stepper Motor Actuators
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.
All have bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors. The splined shaft keeps the rod from rotating as it extends and retracts.
Travel distance per full step determines the control you have over the actuator's positioning. The smaller the measurement, the finer positioning control you have, but the more steps it will take to go the same distance.
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.

Multi-Axis Stepper Motor Actuators
Precisely drive both linear and rotary motion from one compact system. Often found in pick-and-place equipment, these actuators have two stepper motors. Each stepper motor drives one type of motion, and you can control them separately. When stopped, they hold their position even when a counteracting force is applied to the load.
Actuators with an encoder are useful in applications where relative positioning is critical, such as coordinating motion between multiple actuators. The encoder monitors the position of the actuator and reports back to a controller (not included), which adjusts or stops the shaft if it isn’t in the right place.
To confirm which actuator will work for your application, click on a part number and select "Product Detail" to view the torque-speed curve and dynamic load-speed chart. Holding torque is the force needed to move the actuator out of position when it’s stationary. When the actuator is rotating, torque generally decreases as speed increases. Dynamic load capacity is the maximum load an actuator can move linearly. If you increase the speed, the dynamic load capacity decreases.
Travel distance per full step determines the control you have over the actuator's linear positioning. The smaller the measurement, the finer positioning control you have, but the more steps it will take to go the same distance.
Full step increment refers to how much the actuator rotates when it takes a full step. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.
All actuators require a controller and two motor drivers (not included).
