The patented TriAdapt® motor coupling has been proven
in the ServoFit™® Precision Planetary
gearheads. It is designed to allow thermal expansion of
the motor shaft–ensuring
long motor life by preventing thrust load on the motor
bearings. Some features are:

- TriAdapt motor shaft adapter system allows installation of motor in minutes - no special tools required and is made from light weight aluminum for low inertia
- Triple-split collet - for greater concentricity and low inertia
- Will fit a wide selection of IEC, NEMA, or customized
motor adapters
- Adapter bushings to fit all motor shafts – no
key required
- Motor plate pilot toleranced to fit your motor for precise concentricity
- Motor plate can easily changed to fit your choice of motors
STOBER ServoFit™ SMS Gearheads will fit the motor of your choice by assembling the correct motor mounting plate between the motor and the reducer. When ordering an SMS reducer, specify the motor manufacturer and part number, provide the motor drawing with dimensions (preferred), or specify the motor mounting dimensions to be sure the correct mounting plate is provided.
