Steel Bellows Clamping Shaft Coupling Stepped For Encoder

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

> The material is aluminum alloy, and the middle bellows is made of stainless steel with excellent corrosion resistance
> Laser welding is used between bellows and shaft sleeve, with zero rotation clearance, suitable for forward and reverse rotation
> Bellows structure can effectively compensate radial, angular and axial deviation
> Designed for servo motor stepper motor
> Fastening method of clamping screw
