The coupling shall be operated, mounted, maintained and repaired by authorized, trained and instructed personnel only. In the interest of further development, we reserve the right to carry out modifications serving the technical progress. BAWS 010-GBR-1 RINGFEDER ® TNS SX - 2 -... -
Page 3: Technical Description
• The coupling must only be operated in normal industrial atmospheres. Since aggressive media may attack the coupling components, screws and elastic buffer rings, they repre- sent a risk for the operational safety of the coupling. Consult RINGFEDER POWER TRANSMISSION in such cases. -
Page 4: Coupling Marking
The coupling parts can be stored in the delivered state in a dry place under roof at normal ambient temperatures for a time period of 6 months. Storage for a longer period requires the application of a long-term preservation. (Please consult RINGFEDER POWER TRANSMISSION in this respect.) The buffer rings must not be exposed to ozonic media, direct sun light or intensive light sources with UV light. -

Page 14: Operation
When operating the coupling, its specific technical data have to be carefully observed (see chapter 6 ‘Technical Data’). These values must never be exceeded without the prior written approval by RINGFEDER POWER TRANSMISSION. In order to ensure trouble-free and reliable performance of the coupling, the coupling has to be designed according to the selection specifications, e.g. - Page 15 Inspect elastomer for wear forces act on connected ma- chines.
