Aluminum alloy bellows setscrew coupling for motor starter

Product introduction

Bellows couplings are used where precise rotation, high speeds, and dynamic motion must be transmitted. They exhibit zero backlash and a high level of torsional stiffness, offering distinct performance advantages. But proper sizing and handling are critical to theirsuccessful implementation.

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 setscrew
