The new SP3 coupling features an integral clamping ring system, with the base hub components held to a very high level of concentricity between the two respective bores during the assembly process. The external clamping ring provides the advantage of symmetrical construction even when it comes to the small amounts of deformation during clamping compression onto the shafts. Any small inconsistencies in tightening the clamping system are contained to the ring itself, with the coupling straightness remaining highly accurate during installation.
Available sizes range from 60 Nm to 500 Nm, with much higher torque capacities, custom flanges and materials on request.
