Product Description
GR 20X32 Aluminum Alloy Bellows Setscrew Coupling For Mechanical
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.
