ROFLEX® SH Split torsionally flexible, failsafe shaft coupling

Shaft coupling with elastomer elements that can be replaced when installed

The torsionally flexible, failsafe shaft coupling ROFLEX SH Split is a short, three-part shaft coupling for torsional vibration damping power transmission.

The torsionally flexible jaw coupling ROFLEX SH Split is an elastomer coupling with fracture separated/cracked hubs (SH SPLIT). 
This design is also referred to as half shell coupling, clamping coupling, coupling with split hubs or elastomer coupling with split clamping hub.

The coupling transmits torques up to 1,800 Nm.

The split hubs allow to assemble and disassemble the coupling radially without having to shift the adjacent power packs. Before start-up each electric motor must be subjected to a torsional direction inspection to prevent damage to the drive.

With ROFLEX SH this can be done without any problem and can be implemented locally at the site. The coupling is used in general mechanical engineering and is thus suitable for numerous applications, often between IEC motor or Nema standard motor and industrial gearbox where it is mounted as a high-speed coupling on the motor side. Anyway, it is mainly applied in the pump industry between electric motor and pump.

Benefits of couplings with split hubs:

The three-part ROFLEX SH Split shaft coupling allows to offset positive locking fit without shifting driving and driven side axially. The elastomer elements can be replaced when installed.
