Flexible Mechanical Power Transmission Coupling - 400 Series (Unbored)

The flexible mechanical drive coupling connects the motor shaft to the pump (or other equipment) shaft, transmitting torque and absorbing minor misalignments (parallel, angular, and axial) and the 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 400 Series and is supplied undrilled (R code): the bore and keyway are machined to fit your shaft (up to a maximum of 1-7/8"). Ideal when you need a special size.

General Specifications:

• Material: Magnesium alloy cast in a permanent mold and heat-treated (76% lighter than cast iron and stronger than iron or aluminum).
• Component: Undrilled (blank) individual hub, ready for custom machining.
• Maximum bore size: 1-7/8"
