PE Series: INLINE — Shaft Output Features • 3:1 to 100:1 ratios • Helical gearing produces more torque while running quieter compared to spur tooth gearing • Input coupling design transfers more torque with lower inertia for vibration free operation • Large motor input option to accept bigger diameter motor shafts so you don’t use an oversized gearbox • Error free motor mounting and quick changeover with toleranced pilot on motor plate • Low no load running torque, giving you more torque for your application • Optional food grade grease (Contact STOBER.) • Build and ship in one day • Assembled in the USA STOBER PE Series ServoFit ® Precision Planetary Gearheads are available for applications where very low backlash is not important. They are an economical helical tooth planetary, comparable in quality to other STOBER units. Every gearbox is made to order. STOBER will custom whatever you need to fit your application.
