Inline Servo Gear Units

Inline Servo Gear Units

STOBER servo inline gear units are unrivaled in their precision and 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
The World’s Toughest Gearboxes
STOBER inline servo gear units offer unparalleled precision, power, and flexibility.

Choose from planetary gearing or helical bevel. With options for bearings or reduced backlash, we can optimize our products to match your application.
KSS: For the toughest environments
The P series features planetary gearing, providing unsurpassed smoothness and precision.

It is incredibly efficient, has low backlash, and runs quiet.

Plus, you can choose from several bearing options to handle radial or axial loads, optimizing your machine design.

P gearboxes are available as compact planetary servo geared motors or they can be mounted to any motor with our toleranced motor adapter.
K/KL: For right angle applications
The C series utilizes helical gearing for up to 97% efficiency.

Choose the housing style that fits your application – round or square flanges, tapped holes, or foot mounting.

C gearboxes are available as compact planetary servo geared motors or they can be mounted to any motor with our toleranced motor adapter.
KSS: For the toughest environments
The PH series offers superior stiffness and accuracy
It offers a reinforced bearing option for applications with higher axial loads.

PH gearboxes are available as compact planetary servo geared motors or they can be mounted to any motor with our toleranced motor adapter.
KSS: For the toughest environments
The PE series is an attractive option for applications that don’t require the highest precision or smoothness.

Its unique for an economy option because it utilizes helical gearing.

PE gearboxes are available as compact planetary servo geared motors or they can be mounted to any motor with our toleranced motor adapter.
KSS: For the toughest environments
The PHQ series features four planetary gears, making it the most powerful gearbox on the market.

It provides smooth operation while producing huge amounts of torque.

PHQ gearboxes are available as compact planetary servo geared motors or they can be mounted to any motor with our toleranced motor adapter.
