Aluminium four-beam clamp coupling, 3/8 inch bore, 1 inch diameter, 1-1/4 inch length

Ruland Manufacturing

Ruland Manufacturing PCR16-6-6-A Coupling 4 Beam Clamp 3/8 in Bore

SKU CH-2TD8-QETZC

Four-beam aluminium coupling clamps two 3/8 in shafts, handles 30 in-lb torque at 6,000 RPM

  • Precise alignment with 3° angular misalignment tolerance
  • Handles 30 in-lb torque at 6,000 RPM
  • Four-beam design gives 5 in-lb/Deg torsional stiffness
  • Clamp-on locking secures 3/8 in shafts without marring
  • Compact 1 in OD fits tight machine spaces

4-Beam Aluminium Clamp Coupling

This 4-beam clamp coupling joins two 3/8-inch round shafts in motion-control systems. The aluminium body provides a 1-inch outside diameter and an overall length of 1 1/4 inches for compact installations. It transmits up to 30 in-lb of torque at speeds up to 6,000 RPM.

Verify shaft size and misalignment limits

Confirm both shafts measure exactly 3/8 inch in diameter and are round before ordering. The coupling accommodates up to 3 degrees of angular misalignment and 0.015 inch of parallel offset. Axial motion is limited to 0.01 inch, so ensure the application stays within this range.

Sustained load behaviour and compliance notice

Under continuous operation the torsional stiffness of 5 in-lb per degree maintains consistent positioning without wind-up. The aluminium construction dissipates heat during extended runs at the rated 6,000 RPM limit. California Proposition 65 warnings apply for cancer and reproductive-harm substances.

Questions about this item

Does the PCR16-6-6-A coupling come with mounting hardware or must I buy screws separately?

The coupling uses a clamp-on locking type with four beams; the description lists only the coupling itself, so mounting screws are not included and must be sourced separately.

Should I choose a different bore size or is the 3/8 in bore the only option for this model?

The supplier title and facts both state bore diameter 1 and bore diameter 2 are 3/8 in, and "Different Bore Sizes No" confirms this model is only offered with matching 3/8 in bores.

What does the 30 in-lb maximum torque mean for my 6,000 RPM application?

At up to 6,000 RPM the coupling can transmit 30 in-lb of torque while accommodating 3 degrees angular misalignment, 0.015 in parallel offset and 0.01 in axial motion.
