Shaft Designs


- Solid shaft with key
- Solid shaft without key
Bearing Design


- Reinforced bearings for higher axial load capacity (option)
Mounting Positions


- Any mounting position.
Lubricants and Maintenance


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


Black RAL 9005
Motor Adapter MF


- Universal motor mounting system for almost all synchronous servo motors. 
- Option large (MFL) for large motors.
- Fast and secure motor mounting.
- Integrated FlexiAdapt® clamp coupling for motor shafts without key. 
- Robust, balanced coupling. 
- Thermal length compensation with flexible bellows coupling.
FlexiAdapt
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
Option ServoCool


- Ventilation system for motor adapters ME and MF.
- With integrated radial fan. 
- Allows operation at higher speeds or higher surrounding temperatures or helps reduce the temperature on the axis.
- Universal motor mounting system for almost all synchronous servo motors. 
- Option "large" for large motors.
- Fast and secure motor mounting.
- Integrated clamp coupling for motor shafts without key. 
- Robust, balanced coupling. 
- Thermal length compensation.
