Rigid Shaft Coupling Specifications

This Climax Metal Products RC-100-KW coupling connects two shafts using a one-piece carbon steel construction. It features round keyed bores with set screw locking and integrated keyways for secure torque transmission. The unit is supplied new and suits industrial power transmission applications.

Capacity and Operational Limits

The coupling handles a maximum torque of 563 in-lb and operates up to 1,800 RPM. A clearance diameter of 1.5 in accommodates the shaft assembly within the 3 in overall length. These ratings define the mechanical headroom for continuous duty cycles.

Upgrade Context and Fitment

This component replaces worn or undersized rigid couplings where keyed shaft engagement is required. The jump is justified when existing hardware cannot meet the 563 in-lb torque rating or 1,800 RPM speed limit. It is not suited for applications needing flexible misalignment compensation or higher torque capacity.

Questions about this item

Will the 1.5 in clearance diameter of this RC-100-KW coupling fit around the flange on my existing 3/4 in shaft?

The coupling has a 1.5 in clearance diameter and a 3/4 in maximum bore, so it will slide over a 3/4 in shaft as long as the flange on your old hardware is smaller than 1.5 in.

How can I verify the coupling is transmitting torque correctly after installation?

Run the shaft up to the rated 800 RPM and confirm smooth rotation without vibration; the coupling is rated for 563 in-lb of torque, so any binding or noise indicates misalignment or loose set screws.

Does the box include the keyway inserts or must I supply my own keys?

The coupling is a one-piece carbon-steel unit with integral keyways 1/4 in wide and 1/8 in deep on both bores; you only need to provide standard square keys matching those dimensions.
