NEMA 8 Double Stacked Thickness stepper motor linear actuators have the same cross-section side length but a thicker length, so its force has been greatly improved. The stepper motors are especially suited for applications with stringent requirements for structural space, and can achieve maximum thrust with minimum space.
- 3 designs are available, captive, non-captive and external linear version.
- Resolutions from 0.001524 mm per step to 0.04 mm per step.
- Delivers force of up to 7.5 kg.
