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 007-GBR-1 RINGFEDER TNS SDD-5, TNS SDDL-5 - 2 -...
• 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.
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.

• The maximum permissible bore diameters must not be exceeded. • Check whether the shaft-hub connections safely transmit the occurring operating torques. • The standard tolerance of RINGFEDER® TNS for finish bores is fit H7. • Standard keyways comply with DIN 6885, sheet 1.
• Axially lock the hub, for example by means of a setscrew on the back of the hub above the keyway Consult RINGFEDER POWER TRANSMISSION in case of other shaft-hub connections. • The stated maximum bore diameters are valid for keyed connec- tions according to DIN 6885/1 and must not be exceeded.
Observe deviant agreements, which may exist! • When tightening setscrews, secure them with an adhesive, such as e.g. Loctite 222, to prevent the screws from working loose and dropping out. Fig. 4 ® BAWS 007-GBR-1 RINGFEDER TNS SDD-5, TNS SDDL-5 - 10 -...

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.

10 Maintenance The flexible coupling RINGFEDER® TNS SDD-5 / TNS SDDL-5 only requires little maintenance during operation. The elastic buffer ring is subject to wear. The time at which the wear limit of the elastic buffer ring is reached depends on the service parameters and application conditions.
• Tighten the screwed connections of the claw rings to the proper torque M specified in table 2 (Fig. 6). • Check the alignment of the coupling according to the instructions given in chapter 8 ‘Coupling Alignment’. ® BAWS 007-GBR-1 RINGFEDER TNS SDD-5, TNS SDDL-5 - 22 -...
The cover must not touch the coupling and impair the proper operation of the coupling. We do not assume any responsibility or warranty for any damages resulting from the use of accessories or spare parts, which have not originally been manufactured by RINGFEDER POWER TRANSMISSION. 11 Disposal Disposal of the parts must be arranged in accordance with the regulations and laws of the country where the equipment is installed.
