Ruland Manufacturing

Ruland Manufacturing CLX-19-19-F Rigid Shaft Coupling 1-3/16in

SKU CH-74C6-K69KQ

One-piece carbon-steel rigid shaft coupling joins two 1-3/16 in round shafts at up to 4,000 RPM and 5,000 in-lb torque

  • One-piece carbon-steel construction eliminates backlash
  • 1-3/16 in bore on both ends for direct shaft fit
  • 24 in clearance diameter clears surrounding components
  • Rated to 4,000 RPM for high-speed drives
  • Handles up to 5,000 in-lb torque load

One-Piece Carbon Steel Coupling

The Ruland CLX-19-19-F is a one-piece rigid shaft coupling machined from carbon steel. It connects two shafts that each measure 1-3/16 inches in diameter. The unit suits applications where precise alignment can be maintained and zero backlash is required.

Thermal and Power Behaviour

As a solid mechanical component the coupling generates no heat of its own and operates silently. It transmits torque up to 5,000 in-lb at speeds up to 4,000 RPM without adding measurable power draw to the drivetrain.

California Proposition 65 Notice

The product carries a Proposition 65 warning for exposure to a chemical known to the State of California to cause cancer and reproductive harm. No accessories, lubricants or software are included with the coupling.

Questions about this item

How do I install the CLX-19-19-F rigid coupling on two 1-3/16 in shafts without misaligning them?

Slide the one-piece carbon-steel body over both round bores, then tighten the set screws evenly while rotating the assembly to keep the 2.24 in clearance diameter centred; the step most people miss is checking angular alignment with a dial indicator before final torque.

What wear items or maintenance will the CLX-19-19-F need after extended service?

The coupling itself has no moving parts, so only the set screws and keyway interfaces may loosen; inspect screw torque and bore fretting at each scheduled shutdown and replace the unit if corrosion from the Prop 65-listed chemicals appears.

At what point does the CLX-19-19-F hit its limit during continuous high-speed operation?

The 4,000 RPM maximum speed is the first hard limit; sustained running at or above that speed risks exceeding the 5,000 in-lb torque rating and can accelerate fatigue in the carbon-steel body.
