  • TypeCouplings, Collars & Adapters
  • Two-piece clamp design simplifies installation on fixed shafts
  • 1 in round keyed bore fits standard shaft sizes directly
  • Carbon steel construction handles up to 4,000 in-lb torque
  • Rated for 4,000 RPM maximum rotational speed

Rigid two-piece coupling for 1 in shafts

This carbon-steel rigid coupling joins two 1 in round keyed shafts with a clamp-on locking design. The two-piece construction allows installation without moving adjacent components, suiting maintenance on fixed equipment. It transmits up to 4,000 in-lb at speeds up to 4,000 RPM.

Suited for in-line shaft connections needing zero

Buyers needing misalignment compensation, vibration damping or flexible coupling types should consider other designs. Applications requiring corrosion-resistant materials or non-metallic construction are not served by this carbon-steel unit.

Fits 1 in keyed shafts with 1/4 in keyway

The coupling clamps directly on each shaft, eliminating the need for set screws or additional locking hardware. Its 3 in overall length and 1 3/4 in outside diameter keep the assembly compact while the two-piece split frees up axial space during installation and removal.

Questions about this item

Do I need a 1 in round keyed shaft on both sides for this coupling to clamp on?

Yes, both bores are 1 in round keyed so each shaft must match that diameter and keyway profile.

Will the 1 3/4 in outside diameter clear the adjacent bearing housing I already have?

The coupling OD is 1 3/4 in with a 2.05 in clearance diameter, so compare those dimensions to your housing bore.

How can I confirm the two-piece clamp is seated correctly after installation?

Torque the clamp screws to the manufacturer specification and verify the shafts turn freely up to 4,000 RPM without vibration.
