WJA Drum Coupling

Spherical Roller

WJA Drum Coupling is a spherical roller coupling, which is composed of jacket with connecting flange, spherical roller, semi-coupling, inner and outer cover plate and sealing system, capable of transmitting large torque and bearing radial load. The connection between the coupling and the output shaft of the reducer adopts an involute spline pair design.
