Product Description

GR Aluminum alloy bellows setscrew coupling

Description of GR Aluminum alloy bellows setscrew coupling
>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 mot
