Ruland CLX-16-12-F Rigid Coupling

This one-piece rigid shaft coupling connects two round shafts of different diameters using a carbon steel construction. It suits maintenance and assembly tasks where precise alignment is maintained and zero backlash is required between driving and driven components.

Suited for fixed-alignment shafts up to 4 000 RPM

Builders needing flexible misalignment compensation or vibration damping should select a different coupling style. Applications requiring keyway engagement or bore sizes outside the 3/4 in to 1 in range are not compatible with this model.

Carbon steel body handles 4 000 in-lb continuous

The one-piece design transmits full rated torque at speeds up to 4 000 RPM without the wear points found in multi-piece assemblies. Sustained operation stays within material limits when shafts remain accurately aligned and lubricated.

Questions about this item

What shaft sizes must my equipment have for the CLX-16-12-F to fit?

One shaft must measure 1 in and the other 3/4 in; both need round bores to match the coupling.

Will the 4,000 RPM limit of the CLX-16-12-F restrict an older motor that runs slower?

No — the coupling handles up to 4,000 RPM, so any motor at or below that speed is within its range.

How can I confirm the CLX-16-12-F is seated correctly after installation?

Check that both shafts sit flush against the internal shoulder and the coupling does not wobble when rotated by hand.
