Page 3: Technical Description
TRANSMISSION. 2 Technical Description The RINGFEDER® TNS S-St / TNS S-LSt coupling is a torsionally flexible, puncture proof claw coupling. It compensates for angular, radial and axial shaft misalignments within defined limits. The coupling transmits torque through elastic buffers loaded in shear. These buffers come in Perbunan (Pb) or polyurethane (Vk), as standard in Vulkollan red (VkR), and are connected to each other to form a buffer ring. -
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 Check coupling parts for damages products buffers deterio- and replace parts, if necessary rate.
