Climax Metal Products 2CC-150-150 Rigid Steel Coupling Conduit

SKU CH-XHC4-ZJ4DP

A rigid steel shaft coupling with a two-piece clamp design, 2.5 inch outside diameter, 2.5 inch overall length, 3700 in-lb maximum torque and 4000 RPM rating

  • Rigid steel construction provides high torque capacity up to 3,700 in-lb
  • Two-piece clamp design allows installation without shaft disassembly
  • Black oxide finish resists corrosion in harsh environments
  • Precision 1-1/2 inch bore ensures accurate shaft alignment
  • Rated for continuous operation at 4,000 RPM

Steel rigid coupling for 1 1/2 inch shafts

This rigid steel coupling joins two 1 1/2 inch diameter shafts in a fixed alignment. The two-piece clamp design uses 1/4-28 screws to secure the connection without a keyway. It suits machinery that requires zero backlash and high torque transmission up to 3,700 in-lb.

Replaces flexible or keyed couplings

Upgrade from flexible couplings when angular misalignment must be eliminated and torsional stiffness is critical. The jump is worth it for drives running up to 4,000 RPM where consistent phasing outweighs the need for vibration damping or easy disassembly.

Limited to exact shaft match

The 2 1/2 inch outside diameter and 2 1/2 inch overall length demand precise shaft preparation and near-perfect alignment. It cannot accommodate parallel or angular offset, so mounting surfaces and bearing supports must hold tight tolerances throughout the operating range.

Questions about this item

What shaft diameter does the 2CC-150-150 rigid steel coupling fit?

The coupling accepts a 1 1/2 inch bore diameter on each shaft end, giving a 2.5 inch outside diameter and 2.5 inch overall length when installed.

How do I install the two-piece clamp coupling and what step is often missed?

Slide both clamp halves over the aligned shafts, insert the 1/4-28 screws, then torque them evenly to the rated 3,700 in-lb limit; skipping the even-torque step causes misalignment and premature wear.

What maintenance or replacement should I plan for with this coupling?

Inspect the black-oxide finish and screw threads at regular intervals; replace the coupling if corrosion, thread damage, or excess backlash appears, especially when running near the 4,000 RPM maximum.
