Right Angle Servo Gear Units

STOBER servo right angle gear units are unrivaled in their options. Choose from planetary gearing or take advantage of helical gearing. Servo doesn’t have to mean planetary!

These gear units can be mounted to any motor with our toleranced motor adapters or you can add a STOBER motor on them to make a geared motor. These units are assembled in our Maysville, Kentucky facility, shipped in one day, and come with a 5 year warranty.

BENEFITS
