PowerRing™ Couplings integrate the Stafford PowerRing™ Shaft-Hub Lock design to transmit up to three times the torque load of conventional clamp-type couplings, without the need for keyways. They are balanced for high speed operation with minimum vibration.
Transmit 3X the torque of clamp-type couplings
Balanced for high-speed operation
Maintains shaft alignment
Finished bore on other side protects shafts from damage
