Power is transmitted via pre-compressed rubber. It excels at absorbing vibrations and shocks, and also reduces noise from machinery. The elastic rubber component consists of a polygonal rubber body with aluminum inserts at its vertices. Only the rubber body and mounting bolts are included.

  • The maximum rotational speed does not take dynamic balance into account.
  • As a general rule, the dynamic torsional spring constant is approximately 1.3 times the static torsional spring constant.
  • The moment of inertia and mass listed above are assumed to be equivalent to those of the S0 type.
