Climax Metal Products Rigid Steel Coupling 2 Piece Clamp 1 3/4 in Bore Keyway

SKU CH-CCC9-TJWDY

Rigid steel coupling joins 1 3/4 in shafts with a 3/8 in keyway and 5/16-24 clamp screws for up to 310 in-lb torque at 4,000 RPM

  • Rigid steel construction delivers high torque capacity
  • 8,310 in-lb maximum torque handles heavy loads
  • Two-piece clamp design simplifies shaft installation
  • 1 3/4 inch bore with 3/8 inch keyway ensures secure fit
  • Black oxide finish protects against corrosion

Rigid Steel Coupling 1 3/4 in Bore

This rigid shaft coupling joins two shafts with a 1 3/4 in bore diameter. The two-piece clamp design allows installation without removing other components. A 3/8 in keyway prevents rotational slip. It is suited for mechanical power transmission assemblies.

Thermals Noise and Power Draw

The coupling is a solid steel component with no moving electrical parts, so it generates no heat and produces no audible noise during operation. It draws no power and requires no electrical supply. Normal use adds no thermal load to the surrounding system.

Sustained Load Behaviour

Rated for a maximum torque of 8,310 in-lb and speeds up to 4,000 RPM, the coupling maintains alignment under continuous duty. The black oxide finish resists corrosion in industrial environments. The clamp screws secure the halves at a 5/16 in -24 thread size for consistent clamping force.

Questions about this item

How do I install the 2-piece clamp coupling on a 1 3/4 in shaft with a 3/8 in keyway, and what step is often missed?

Slide both clamp halves over the aligned shafts so the 3/8 in keyway engages the key, then torque the 5/16 in.-24 screws evenly; the step often missed is tightening the screws in a cross pattern to reach the 8,310 in-lb rating without distortion.

What maintenance or replacement will the rigid steel coupling need after extended service?

Periodically check the 5/16 in.-24 screw torque and inspect the black-oxide finish for wear or corrosion; replace the coupling if the keyway walls show deformation or if the 3.0 in outside diameter shows cracking.

At 4,000 RPM continuous operation, which limit of this coupling appears first?

The 4,000 RPM maximum speed rating is the first limit reached under sustained use; exceeding it risks centrifugal stress on the 3.0 in diameter steel body before the 8,310 in-lb torque capacity becomes a factor.
