Power is transmitted using a polyester resin with elastic properties comparable to those of rubber. This coupling excels at absorbing vibrations and shocks, and offers superior environmental resistance—including heat, cold, and oil resistance—that cannot be achieved with natural rubber. The O0 type features a resin element and an aluminum insert.

  • The maximum rotational speed does not take dynamic balance into account.
  • Since the dynamic torsional spring characteristics are nonlinear, the dynamic torsional spring constant is applicable at approximately 20% or more of the rated torque.
  • As a general rule, the dynamic torsional spring constant is approximately 1.3 times the static torsional spring constant.
  • The values for moment of inertia and mass apply to cylindrical and flanged hubs with a through-hole.
