Servo Gear Units with Brake

STOBER’s servo gear units can be paired with our ServoStop, an integrated safety brake. It’s ideal for vertical applications and provides redundant braking. It prevents slipping or falls, even when the motor is removed.

BENEFITS
The World’s Toughest Gearboxes
ServoStop is a revolutionary safety brake that provides dynamic braking during power failures or emergency stops in hazardous situations. It is integrated into the gearbox and prevents accidental sliding or falling of vertical axis. The servo motor can be dismounted even with the brake engaged. Let us optimize your machine design today!
The C series can be integrated with a ServoStop safety brake. This 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.

The F series can be integrated with a ServoStop safety brake. This series offers compact size and flexibility, as well as optimal efficiency due to the helical bevel gearing. Choose from a variety of housing styles and output options.
The K series can be integrated with a ServoStop safety brake. This series is unparalleled when it comes to right angle options. Its unique design allows you to use a variety of outputs, including shaft, hollow bore, shrink rings, and bushings.

Housing options include flange, feet, and torque arm

The K unit features helical bevel gearing, providing smooth motion and optimal efficiency.
The P series can be integrated with a ServoStop safety brake. This 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.
The PH series can be integrated with a ServoStop safety brake. This series offers superior stiffness and accuracy.

It offers a reinforced bearing option for applications with higher axial loads.
The PHK series can be integrated with a ServoStop safety brake. This series combines our planetary PH series with a K series input.

This gear unit features quiet operation, higher ratios, and higher input speeds compared to a KX series unit.

The PHQ can be integrated with a ServoStop safety brake. 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.
The PHQK can be integrated with a ServoStop safety brake. This series series combines our planetary PHQ series with a K series input.

This gear unit features the highest acceleration torque and torque density.

The PK series can be integrated with a ServoStop safety brake. This series combines our planetary P series with a K series input.

This gear unit offers quieter operation, higher input speeds, and higher ratios compared to a KX unit.
