3 Marking of the coupling 

The product line RINGFEDER

®

 TNM has its hardness in Shore (A) indicated on the 

elastic intermediate ring.  

4 Storage 

On receipt of the goods, the supply is to be checked immediately for completeness and 

correctness. Possible damages incurred during transit and / or missing parts are to be 

notified in writing. 

The coupling parts can be stored in their delivered standard-state for 6 months in a dry, 

roofed place at normal room temperature. For a longer storage duration a long-term preser-

vation is necessary (consult RINGFEDER POWER TRANSMISSION). The elastic 

intermediate ring must not be subjected to ozone containing mediums, direct solar 

influence or strong light sources with ultraviolet

-

light. The relative humidity must not exceed 

65%. In the case of proper storage the characteristics of the elastic intermediate ring 

remain unchanged for almost up to three years.
