Shaft Coupling

Coupling is a core component that transmits power and motion
from the driving shaft to the driven part while absorbing misalignment
and any possible factors that could reduce efficiency of machines
(e.g. vibration, noise, electric current, etc.)

  • The Moment of Inertia and Mass values are based on products with max. Inner diameter.
  • Max. torque/rated torque is the value regarding to a coupling’s self-durability and is not related to slip-torque between the coupling bore and the shaft.
