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.
  • Permissible 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. (Set-screw type is usually less durable than other clamping method, thus please consider it has a complementary option e.g. keyway along with.)
  • OD 126 & 144: Please refer to * marked values for D2 when ID is over 55mm (OD126) and 66mm(OD144)

  • The recommended shaft tolerance is h7.
  • Custom process (e.g. non-standard Inner diameter, special tolerance etc.) is also available upon a special request in prior to order placement.
  • Keyway is available. (Optional)
  • Due to interference of the middle parts, make sure the shaft is only inserted into L1 depth for IDs with ★ mark. Consult us first if you’re concerned about misalignment.
