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.)

Application : Semi-conductor manufacturing machine, SMT, Cartesian Robot, UVW Stage, Machine tools, Index Table, and Corrosion resistant / High-precision / High-heated environment

Why Stainless Steel Products are recommended?

1. Corrosion Resistance allows to be used in rusty environment.
2. The heat resistance is better than aluminum alloy material’s so that it keeps the mechanical properties of materials staying normal in high temperature applications.
