Slip ring module system (SM)
Modular all-round system

The SM System is predominantly used for welding turntables and in automation engineering for the automotive industry and its suppliers. Here too, rotary transmission of electricity and gaseous and/or liquid media is also possible. The SM System is installed in dust and/or water-tight ball bearing housings. Thanks to the modular design, all the cutomer's requirements can be satisfied. Maintenance with a contact oil after every one million revolutions is prescribed. A service life of 7 to 10 million revolutions can then be achieved.
Can be combined with all MR products.
Application examples
- Turntables / positioners
- Military engineering
- Reel changers in the printing and packaging industry
- Bottling plants
- Turntable ladder vehicles
- Textile industry
- Construction machinery
