Rigid Shaft Coupling for Precision Builds

This new Ruland Manufacturing coupling connects two shafts with identical 7/8 in round keyed bores. The one-piece carbon-steel construction handles up to 3,600 in-lb of torque at 4,000 RPM. Collectors and engineers seeking a factory-fresh power-transmission component will find the specifications match the original SCC-14-14-F design.

One-Piece Carbon Steel Fits Directly onto Keyed

The coupling requires no additional adapters because both bores share the same 7/8 in diameter with 3/16 in keyway width and 3/32 in keyway depth. Set-screw locking secures the hubs without separate fasteners, freeing up the 2-1/2 in overall length for compact drivetrain layouts. A 1.63 in clearance diameter ensures the body clears adjacent hardware.

Set-Screw Hardware Included for Immediate

Supplied set screws engage the keyways directly, so no extra locking collars or keys are needed to transmit the rated 3,600 in-lb torque. The carbon-steel finish arrives uncoated, allowing builders to apply their preferred corrosion protection. California Proposition 65 notices apply to the material composition.

Questions about this item

How much torque can the Ruland SCC-14-14-F rigid shaft coupling transmit before it reaches its limit?

The coupling is rated for a maximum torque of 3,600 in-lb, which is the limit that appears first under sustained use.

Does the carbon-steel coupling generate noticeable heat or noise when running continuously at 4,000 RPM?

The one-piece carbon-steel construction has no moving inserts, so it runs quietly and heat buildup stays minimal at the rated 4,000 RPM speed.

What shaft sizes must I already have to mount this coupling without additional machining?

You need two shafts with a 7/8 in bore and matching 3/16 in keyways to fit the coupling's fixed bore diameter and keyway width.
