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. -
