Rigid Coupling is a rugged mechanical coupling device designed to transmit torque and maintain precise alignment of two shafts. It has high strength and torsion resistance and is suitable for applications that require precise docking, such as industrial equipment, automation systems, and heavy machinery. Its inelastic properties enable it to transmit power efficiently and is widely used in motors, pumps, fans, and other mechanical transmission systems.

FAQ
Which scenarios are suitable for rigid couplings?
Suitable for occasions with precise shaft alignment, low speed and heavy load, and high transmission accuracy requirements, such as machine tool spindles, printing machinery, heavy equipment transmission systems, etc.
What should be paid attention to during installation?
The coaxiality of the two shafts must be strictly guaranteed, otherwise the bearings, shafts or couplings themselves will be damaged prematurely due to additional stress. It is recommended to use tools such as dial indicators for calibration.
Compared with elastic couplings, how is the lifespan?
Because there are no vulnerable elastic parts, the lifespan is usually longer under correct installation and maintenance, especially under stable working conditions, which is far better than elastic couplings that require regular replacement of elastic elements.
