NEMA 34 (86mm) Fixed Through Shaft Type Hybrid Stepper Motor

The NEMA 34 (86mm) fixed through shaft type hybrid stepper motor is a heavy-duty captive linear actuator featuring a robust integrated anti-rotation spline mechanism that ensures pure linear extension and retraction without screw rotation. The nut is built into the high-torque rotor, and the spline prevents rotation — converting powerful rotary motion into linear thrust without the need for external guide rails or anti-rotation devices. With optimal stroke lengths under 50mm and thrust capacity exceeding 3,000N, this actuator is engineered for the most demanding applications including heavy industrial machinery, large-format CNC equipment, hydraulic valve actuation, forging press positioning, and mining equipment controls. It delivers maximum force in the most compact possible package.

Structure Type: Fixed Through Shaft (Captive) — Screw extends/retracts linearly, does not rotate. Built-in spline prevents rotation. Best for short-stroke, space-constrained applications.
