Rigid coupling, as the name suggests, is actually a torsional rigid coupling, even under load without any rotary clearance, even when there is a deviation to generate load, rigid coupling or rigid transfer torque.

Rigid coupling is composed of rigid force transmission parts, not relative motion between the connection, so do not have the ability of two axis relative offset compensation, applies only to be joined in installation can strictly for two axis, work does not produce two axes relative offset, flange coupling elastic element, do not have damping and buffering function, Generally, it is only suitable for working conditions with stable load and no impact vibration.

There are two styles of rigid shaft coupling from TIANNIU, which are rigid clamping shaft coupling and rigid setscrew coupling respectively.
