Flexible Mechanical Power Transmission Coupling - 500 Series

The flexible mechanical drive coupling connects the motor shaft to the pump shaft (or other equipment), transmitting torque and absorbing minor misalignments (parallel, angular, and axial) and torsional shocks typical of startup. It works in conjunction with an elastomeric insert (spider) that electrically isolates the shafts and dampens vibration and noise, without the need for lubrication.

This hub corresponds to the 500 Series, machined with a 2-1/8" bore and a 1/2" keyway. Measure the diameter of your equipment's shaft to confirm compatibility.
