Two-Piece Rigid Shaft Coupling

This coupling joins two 1-inch round shafts with a two-piece carbon-steel design. It suits maintenance crews and OEM builders who need a solid, backlash-free connection without the alignment flexibility of a flexible element.

Sustained Load Behaviour

Rated for 2,470 in-lb of torque at up to 4,000 RPM, the coupling transmits continuous power without the wind-up or damping found in elastomeric types. Heat buildup stays minimal because there are no friction surfaces or polymer inserts to degrade under steady rotation.

Interface Practical Limits

The 2.06-inch clearance diameter and 3-inch overall length define the space envelope for mounting hardware and guarding. Both bores are fixed at 1 inch with no keyway provision, so the connection relies solely on clamp force and cannot accommodate shaft misalignment or axial float.

Questions about this item

Does the carbon-steel two-piece coupling run hot or make noticeable noise when driven continuously at 4,000 RPM?

The rigid design has no moving contact surfaces, so it adds no measurable heat or vibration beyond what the shafts themselves produce at speed.

What shaft preparation is required before the 1 in bore coupling can transmit its rated 2,470 in-lb of torque?

Both shafts must be round, 1 in diameter, and free of keyways; the clamp screws provide the sole holding force.

Will the 2.06 in clearance diameter interfere with a legacy 1 in shaft guard I plan to keep?

The guard opening must be at least 2.06 in to pass the coupling flanges without contact.
