Hayes Flywheel Couplings
Hayes Original Flywheel Couplings
Thousands of Hayes Original Flywheel Couplings are in service in gas and tough diesel engines. Torsional vibration is minimized by our flexible neoprene
elements which provide a dampening effect, absorb vibration and reduce shock loads.
The couplings are compact and transmit plenty of torque. Hayes Original Flywheel Couplings are available with a
variety of spline and bores/keys ready to attach to your flywheel. One-piece design. Steel construction.
