Shaft Designs


- Solid shaft with key
- Solid shaft without key (C0 - C5, starting at C6 on request)
Housing Designs


- Pitch circle diameter
- Round flange

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


- Mineral lubricant CLP ISO VG 220
- Option: Synthetic lubricant CLP HC ISO VG 220


Under normal operating conditions no lubricant change is required for gear unit size C0 to C5 (lubricated for life). 
We recommend a change of lubricant for gear unit size C6 to C9 after approx. 10,000 hours of operation.
Paint Finish


- Housing and connector black RAL 9005
- Motor cover b-side magenta RAL 4010

EZ Connection Method (OCS)
Winding Protection


PTC thermistors are installed in STOBER synchronous servo motors as a configuration feature to implement thermal winding protection. This makes it possible for the motor to exceed the maximum permitted winding temperature with the appropriate devices turned off.
