Climax Metal Products RC-100-S Stainless Steel Coupling

SKU CH-ZJQQ-8AFNC

A rigid shaft coupling joins two 1-inch shafts and transmits up to 450 in-lb at 1,800 RPM

  • Stainless steel resists corrosion in harsh environments
  • One-inch bore fits standard inch-size shafts
  • Two-inch outside diameter provides rigid alignment
  • Set-screw fastening secures shaft without keyway
  • Rated for 450 in-lb torque at 1,800 RPM

Rigid Stainless-Steel Shaft Coupling

This rigid coupling connects two 1-inch shafts in a single-piece stainless-steel body. It suits maintenance teams and OEM builders who need a corrosion-resistant joint for light-duty power transmission. The plain finish and set-screw locking keep installation straightforward without keyway machining. Buyers who need a flexible or keyed coupling should select a different style.

Sustained Load Behaviour

Rated for 450 in-lb maximum torque and 1,800 RPM, the coupling transmits steady rotational force without the wind-up found in flexible designs. Stainless construction resists heat buildup and corrosion during continuous operation. The solid body ensures consistent alignment as long as shaft deflection stays minimal. Applications with shock loads or misalignment exceeding a few thousandths of an inch require a flexible alternative.

Build Quality and Mounting

The 2.0-inch outside diameter and 3-inch overall length provide ample screw engagement on each shaft end. Two 5/16-18 set screws secure the bores without a keyway, simplifying field replacement. Plain stainless surfaces withstand wash-down environments and chemical exposure better than plated carbon steel. Installers must verify shaft diameter tolerance and screw torque to prevent slippage.

Questions about this item

How much heat or noise does the RC-100-S stainless steel coupling generate when running continuously at 1,800 RPM?

As a solid mechanical component with no motor or electronics, the coupling itself produces no heat or noise; any temperature rise or sound comes from the connected shafts and bearings.

What shaft size and fastener must I already have to install this 1-inch bore coupling?

You need two shafts with a 1-inch diameter and a 5/16 in.-18 set screw for each hub to secure the coupling in place.

Will the 2.0-inch outside diameter and 3-inch overall length fit alongside the older machinery I plan to keep?

The coupling measures 2.0 inches in outside diameter and 3 inches in overall length, so check your existing equipment for that clearance before installation.
