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.)

Product Features & Application
  • SRB series is one-piece metal coupling with no backlash and absorbs misalignment through its slit structures.
  • SRBS series is made of stainless steel to enhance its corrosion resistance. (However, rust may still occur depending on usage and storage conditions.)

INNER-RELIEF AREA

SRB series has the “relief” space structure in the middle area, in case there is interference that causes damages.

ROUND-SHAPED SLITS

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