3.TECHNICAL DATA:

A: Damping torque: 35-85gf.cm

B: Damping direction: bidirectional

C: Rotational speed max. 50 rpm

D: Lifetime 50,000 cycles (1 cycle = 360° left-hand, 360° right-hand). Even after this time, the dampers still produce over approx. 80 % of their original damping moment. The service life of 50,000 cycles may be significantly higher or lower, depending on the application. Much higher service lives have however been achieved in practice.

E:Operating temperature range -20 °C to +70 °C

4.MOUNTING INFORMATION:

No axial or radial forces may be induced via the shaft.
