Aluminium six-beam clamp coupling, 3/4 by 5/8 inch bores

Ruland Manufacturing

Ruland Manufacturing FCR24-12-10-A 6 Beam Clamp Coupling 3/4 x 5/8 In

SKU CH-ED7Y-FCG28

Six-beam clamp coupling joins 3/4 and 5/8 inch shafts with 80 in-lb torque capacity and 6,000 RPM limit

  • 6-beam design handles 3° angular misalignment for smooth motion transfer
  • Clamp-on locking secures 3/4 x 5/8 in bores without keyways
  • Aluminium body limits inertia at 6,000 RPM max speed
  • 80 in-lb torque capacity with 15.87 in-lb/Deg torsional stiffness
  • 03 in parallel and 0.015 in axial compliance absorb shaft errors

FCR24-12-10-A Six-Beam Clamp Coupling

This aluminum coupling joins a 3/4 inch bore to a 5/8 inch bore using six beams and clamp-on locking. It transmits up to 80 in-lb of torque at speeds up to 6000 RPM while accommodating angular misalignment of 3 degrees and parallel offset of 0.03 in.

Check Bore Sizes and Shaft Tolerances

Verify that both shafts measure exactly 3/4 inch and 5/8 inch round with a clamp-compatible finish. Confirm the available installation length covers the 2 1/4 inch overall length and 1.1 inch through-bore depth. Ensure the application stays within the stated misalignment and axial motion limits.

Thermal Noise and Power Characteristics

The aluminum body dissipates heat from transmitted torque without active cooling and runs silently at rated speed. No external power is required beyond the driving shaft. Observe the Proposition 65 notice regarding chemical content when handling or machining the coupling.

Questions about this item

What comes with the FCR24-12-10-A coupling and do I need to buy screws separately?

The coupling is supplied as a single unit with integrated clamp screws; no additional hardware is required for installation.

How do I choose between the 3/4 in and 5/8 in bore versions of this coupling?

This model has two different bores in one coupling — 3/4 in on one side and 5/8 in on the other — so you do not select a version; you match each bore to the corresponding shaft.

What does the 80 in-lb torque rating mean when the coupling is running at 6,000 RPM on my machine?

At up to 6,000 RPM the coupling can transmit a continuous torque of 80 in-lb while accommodating 3° angular and 0.03 in parallel misalignment.
