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.)

INNER-RELIEF AREA

SRB series has the “relief” space structure in the middle area, in case there is interference that causes damages.
※ Exception Item: SRB-8

ROUND-SHAPED SLITS

SRB series has rounded slits(cuts) structure to disperse stress concentration.
