The TSFNA25 Series Non-Captive Linear Actuators are the perfect choice for cost effective linear motion. The stepper motor internally converts rotary motion to linear motion via a rotating nut and a leadscrew. This actuator eliminates the need for other rotary-to-linear conversions such as belt and pulleys, rack and pinions, or external ball screws. Motion designs can be simplified, production costs lowered and product life enhanced. The motors can be customized to fit your machine requirements. The motor comes in a standard 6-lead configuration and is available in a 4-lead configuration. The winding can be customized to perfectly match your voltage, current, and maximum operating speed. Special screw modifications, cables and connectors are also available upon request.
