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.)

Electroless Nickel Plating for Steel-body Products
- The standard surface treatment (finish) for steel-body product is Black Oxide.
- If corrosion is highly concerned, there is another surface treatment option of ‘Electroless Nickel Plating’ adding an additional code “NI” next to the part no. as shown below.
SHDW-126C-NI-30-40
- All other parts (collars, ASS screws and FAS screws) will be Electroless Nickel Plated as well.
Caution : Slip torque would become lower if the body material or surface treatment of screws are changed from the standard version.
