GM Plum Blossom Type Elastic Shaft Coupling

GM plum blossom type elastic coupling has the advantages of small size, light weight and large transmission torque. The coupling can buffer the vibration during rotation and absorb the impact caused by uneven operation. The coupling can effectively compensate for axial, radial and angular installation errors. Compared with the elastic body of general elastic couplings that bear both bending force and pressure, the GM elastic body is only subjected to pressure, so it can withstand greater loads and longer service life. Compared with the ML type, most GM types use a 4-claw structure, so GM can withstand greater torque under similar sizes. Our company's GM type couplings have a fully processed surface, run smoothly, absorb vibration, and the half couplings are interchangeable, with lower cost of use. GM's standards are close to European standards and can also be used to replace similar couplings on imported equipment.
