The patented TriAdapt® motor coupling has been proven
in the ClassicLine of 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™ Gearheads will fit the motor of your choice by assembling the correct motor mounting plate between the motor and the reducer. When ordering a gearhead, 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.
