Planetary Gearheads offer higher torque performance capabilities for our NEMA 23 frame step motors, both round frame designs and POWERMAX II. These precision speed reducers ensure smooth and accurate operation along with high reduction ratios. They are designed for quick, easy installation and long, maintenance-free service that will optimize your motion control scheme. Planetary gearheads are available alone or factory mounted to steppers.
    However you measure performance, these gearheads have the muscle. Coupled with our patented step motor Sigmax technology they extend dynamic output torques up to 4,240 oz-in. Available in one, two and three stage modular designs with standard ratios to 125:1, low backlash and high torsional stiffness plus case hardened gears and life-time lubrication, they are backed by a two year warranty.
