Climax Metal Products Rigid Steel Conduit Coupling ISCC-100-100-KW

SKU CH-VRQZ-4QF32

Rigid steel shaft coupling with 1 in bore, keyway, 2,470 in-lb torque rating and 4,000 RPM limit

  • Rigid steel construction resists deformation under high torque
  • One-piece clamp design simplifies shaft alignment and installation
  • Keyway included prevents rotational slippage at 4,000 RPM
  • Black oxide finish protects against corrosion in harsh environments
  • 2,470 in-lb torque rating handles demanding power transmission

Rigid Steel Shaft Coupling

The Climax Metal Products ISCC-100-100-KW is a one-piece clamp coupling machined from steel with a black oxide finish. It connects two 1 in shafts in power-transmission assemblies where a rigid, zero-backlash joint is required. The integrated keyway prevents rotational slip between the coupling and the shaft key.

1 in Bore with 1/4 in Keyway

The coupling accepts a 1 in diameter shaft and features a 1/4 in wide keyway that matches standard key stock. A single 1/4 in.-28 clamping screw secures the bore, providing uniform grip without the need for a second fastener or split-hub design.

Rated for 2,470 in-lb at 4,000 RPM

Under continuous operation the steel body transmits up to 2,470 in-lb of torque while the black oxide coating resists surface corrosion. The rigid construction maintains alignment at speeds up to 4,000 RPM without the vibration or wear associated with flexible couplings. Builders needing angular misalignment compensation or higher speed ratings should select a different coupling style.

Questions about this item

What does the 2,470 in-lb torque rating mean for my shaft connection?

The 2,470 in-lb rating is the maximum torque this one-piece clamp coupling can transmit between two 1-inch shafts before slipping occurs.

How does the 1/4-28 screw size limit the coupling's holding power?

The 1/4-28 cap screws provide the clamping force; their size caps the maximum torque at 2,470 in-lb and the speed at 4,000 RPM for a secure rigid connection.

What shaft and space dimensions does the 2.063-inch clearance diameter require?

This coupling fits two 1-inch shafts with 1/4-inch keyways and needs a 2.063-inch diameter clearance space with 2 1/16 inches of axial length to install.
