Output Side
Bearing Design

Pretensioned angular contact bearings at the output in an O-arrangement, ideally suited for helical geared rack and pinion drive.
Mounting Positions

- Any mounting position.
- You can find the explanation of the mounting positions and the respective quantities of lubricant in the document Quantity of lubricant for gear units ID 441871
Lubricants and Maintenance

- Synthetic lubricant CLP HC ISO VG 150
- Lubricated for life
- Maintenance-free
Paint Finish

Black RAL 9005
Motor Adapter ME

- Universal motor mounting system for almost all synchronous servo motors.
- Option large (MEL) for large motors.
- Fast and secure motor mounting.
- Robust, balanced coupling.
- Thermal length compensation.
- Low mass inertia.
EasyAdapt
Option ServoStop

- Integrated in the motor adapter, electrically released spring-loaded brake.
- When the power is removed, in the event of a power failure or an emergency stop ServoStop will brake both drive and machine shaft safely and reliably.
- Zero-backlash plug-in coupling.
ServoStop Motor Adapter with Brake
Recommendation Motor
