Shear Types

Jaure provides a range of safety couplings to prevent the equipment from damage coming from torque overload. The disconnect between driving and driven equipment can be produced by means of shear pins, shear spacers or hydraulic disconnect device (Safeset^®, trademark for Voith).

Increased coupling reliability
Minimized downtime by enabling quick start-up after shear pin breakage
Minimized premature shear pin breakage
Decreased coupling rebuilding cost after shear pin breakage
