Aluminium beam coupling clamp finish 5/8 by 3/8 inch bores

Ruland Manufacturing

Ruland Manufacturing FCR24-10-6-A Coupling 6 Beam Clamp 5/8 x 3/8 in

SKU CH-3CK1-QN4VS

Six-beam clamp coupling joins 5/8 in and 3/8 in shafts, handling 95 in-lb torque at up to 6,000 RPM

  • Product typeCouplings, Collars & Adapters
  • Handles angular misalignment up to 3° for smoother operation
  • Transmits up to 95 in-lb torque in a compact 1 1/2 in OD
  • Clamp-on locking on dissimilar 5/8 in and 3/8 in bores simplifies installation
  • Six-beam aluminum design delivers 23.26 in-lb/deg stiffness with low inertia
  • Rated to 6,000 RPM for high-speed motion-control applications

Ruland FCR24-10-6-A Motion Control Coupling

This aluminium motion control coupling connects shafts with different bore sizes in precision machinery. It suits engineers and maintenance teams who need to transmit torque while accommodating misalignment. The clamp-on locking style provides a secure hold on round shafts without keys or set screws.

Six-beam design handles 3-degree angular offset

The six-beam configuration allows up to 3 degrees of angular misalignment and 0.03 inches of parallel misalignment between shafts. It also compensates for 0.015 inches of axial motion. Torsional stiffness is rated at 23.26 in-lb per degree for responsive motion transfer.

Suits 5/8 and 3/8 inch shafts at moderate speeds

This coupling fits a 5/8 inch bore on one side and a 3/8 inch bore on the other, with a 1.1 inch length through each bore. Maximum torque is 95 in-lb and maximum speed is 6,000 RPM. Buyers needing higher torque capacity, larger bore diameters, or different bore combinations should look at other models.

Questions about this item

What does the 95 in-lb torque rating mean for my application?

It is the maximum continuous torque the coupling can transmit without damage, so your motor and load combination should stay below this value.

What does the 6,000 RPM speed limit cap in practice?

It caps the maximum rotational speed; running the coupling faster risks vibration and premature wear of the six-beam aluminium flexure.

Will the 5/8 in and 3/8 in clamp bores fit my shafts directly?

Yes, the two round clamp bores are machined to 5/8 in and 3/8 in respectively and lock on with the integral clamp screws.
