SRG Models

These are rigid couplings with ultra-high torsional stiffness that were developed for servo motor applications.Unlike flexible couplings, they have no element to absorb differences between the centers of the two shafts, so they have very high torsional stiffness. Since the outer diameter relative to torque can be reduced compared to flexible couplings, smaller couplings can be used, which helps reduce the moment of inertia.

Through-bolt construction
By using a through-bolt construction for the sleeve and hub on one side, the drive shaft and driven shaft can be engaged simply by tightening the pressure bolt on one side.

Taper adapter
Allows coupling via friction when an optional taper adapter is mounted on the tapered shaft of a servo motor.

Clamp type
A clamp-type rigid coupling can also be manufactured.
