GH 20*25 M3 Oldham Type Shaft Coupling For Mechanism Connection​

Products Introduction

Shaft coupling refers to the situation that two parts of the power transmission device and the rotating shaft are not connected together during normal movement. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load and play the role of overload protection.

Oldham type shaft coupling are designed to clamp evenly around the shaft and provide greater retention than fixed screw couplings without damaging shaft. Then tighten the clamping screws to secure. These are Oldham couplings
