Detailed Product Description

GR40X51 M5 Shaft Coupling Aluminum Bellows Setscrew For CNC Machine

Product introduction

Bellows coupling uses corrugated thin-walled pipe (bellows) to directly weld or bond with the two half couplings to transmit motion. The coupling has the advantages of simple structure, small overall dimension, convenient processing and installation and high transmission accuracy. It is mainly used in small power precision machinery and control mechanisms requiring compact structure and high transmission accuracy.

The elastic element of bellows coupling is precision metal bellows, which is divided into flexible series and rigid series. The flexible series has great elasticity and is often used in micro occasions such as encoders and sensors. The rigid series is mainly used in servo motors, CNC machine tools (machining centers) and other occasions.

Products Features

1. The bellows coupling has no clearance and high sensitivity

2. High elasticity, better protection of equipment

3. It can absorb vibration and compensate radial, angular and axial deviations at the same time

4. Oil stain resistance and strong corrosion resistance

5. Torsional rigidity, clockwise and counterclockwise rotation characteristics are exactly the same

6. Commonly used in CNC machine tools, indexing discs and other industrial machinery
