Rigid Coupling for Identical Shafts

This Dayton 6L019 rigid shaft coupling joins two 1-inch round keyed shafts in a fixed alignment. The one-piece carbon steel construction with zinc plating resists corrosion in industrial power-transmission setups. It suits maintenance teams and OEMs who need a permanent, backlash-free connection between matching shaft sizes. Builders needing flexible or tapered-bore couplings should select a different style.

Sustained Torque and Speed Limits

The coupling transmits up to 750 in-lb of torque continuously at speeds not exceeding 800 RPM. Its solid steel body dissipates heat without the wear associated with elastomeric elements under constant load. Operation beyond the rated torque or speed risks keyway deformation and premature failure. Applications with shock loads or higher rotational speeds require a different coupling class.

Simple Press-Fit Installation

Each bore includes a 1/4-inch wide by 1/8-inch deep keyway for positive rotational locking. The 2-inch outside diameter and 3-inch overall length allow straightforward alignment using standard shaft keys and set screws. Installers must verify shaft concentricity before tightening; misalignment causes vibration and bearing damage. No lubrication or periodic adjustment is needed once secured.

Questions about this item

Does the 800 RPM rigid coupling generate noticeable heat or vibration during continuous operation?

The one-piece carbon steel coupling is rated for 800 RPM and 750 in-lb torque with no moving parts, so it runs without generating measurable heat or vibration.

What shaft dimensions and keyway must I already have for the 1 in bore to fit?

Each shaft must be 1 in round with a 1/4 in wide by 1/8 in deep keyway to match the coupling's keyed bores.

Will this 3 in long coupling align with my existing 1 in keyed shafts and 2 in clearance space?

Yes, the 3 in overall length, 2 in outside diameter and dual 1 in keyed bores are designed to connect two identical 1 in shafts within a 2 in clearance envelope.
