  • 450 in-lb torque rating handles heavy-duty loads
  • 4 000 RPM limit suits high-speed applications

Rigid Steel Shaft Coupling

This Climax Metal Products coupling connects two 1/2 inch shafts with a rigid one-piece clamp design. The steel construction with black oxide finish provides secure alignment for power transmission applications. It accepts a maximum torque of 450 in-lb and operates up to 4,000 RPM. No keyway is present on the bore.

Builders needing fixed shaft alignment

The coupling suits installations where zero backlash and precise rotational synchronization are required between identical shaft sizes. It is not for applications needing angular misalignment compensation or vibration damping. Buyers who want flexible or universal joint movement should look at a different coupling style. The single bore diameter limits use to matching 1/2 inch shafts only.

450 in-lb torque rating decides fit

Verify that your application peak torque stays below this limit to avoid slippage or damage. The #8-32 clamp screws secure the shafts at the 1.375 inch outside diameter. Exceeding the rated torque or 4,000 RPM speed risks coupling failure. This single specification determines whether the part matches your drivetrain requirements.

Questions about this item

How much torque can the 1/2 in bore coupling handle before it slips?

The clamp-style coupling is rated for a maximum torque of 450 in-lb, which is the limit reached first under sustained load.

Does the steel body get hot or noisy when running continuously at 4,000 RPM?

At the rated 4,000 RPM the rigid steel coupling runs without measurable temperature rise or audible noise because it has no moving contact surfaces.

Which shaft diameter must I already have for the 1/2 in bore to fit?

You need a shaft with a 1/2 in diameter; the coupling clamps directly onto it using the #8-32 screws provided.
