Climax Metal Products ISCC-087-087 Rigid Steel Coupling

SKU CH-FKND-GHJB8

A rigid steel shaft coupling with a 7/8 inch bore and 2,160 in-lb torque rating

  • Rigid steel construction delivers high torque capacity
  • 2,160 in-lb maximum torque handles demanding power transmission
  • One-piece clamp design simplifies installation and alignment
  • Black oxide finish provides corrosion resistance
  • 4,000 RPM rating supports high-speed applications

Rigid Steel Coupling for 7/8 Inch Bore

This rigid steel coupling connects two shafts with a 7/8 inch bore diameter. The one-piece clamp design uses a 1/4-28 screw to secure the connection without a keyway. It is built for industrial power transmission where a solid, zero-backlash link is required.

Suitable for Inch-Sized Shafts Up to 4,000 RPM

The coupling suits drives running at speeds up to 4,000 RPM and torque loads up to 2,160 in-lb. It is not for applications needing misalignment compensation, vibration damping or metric bore sizes. Builders requiring a flexible or keyed connection should consider a different coupling style.

Maximum Torque Rating of 2,160 in-lb

The peak torque capacity of 2,160 in-lb is the primary limit for safe operation. Exceeding this value risks mechanical failure of the clamp or shaft. Verify that your application's peak load stays within this rating before installation.

Questions about this item

How do I know if the 7/8 in bore diameter matches my shaft?

Measure your shaft diameter; this coupling clamps directly onto a 7/8 in shaft with a 1/4 in.-28 screw and no keyway required.

What does the 2 160 in-lb torque rating mean for my application?

It is the maximum torque the coupling can transmit; ensure your system's peak torque stays below this value to avoid slippage or damage.

How does the 4 000 RPM limit affect my setup?

Do not exceed 4 000 RPM; above this speed the clamp may lose grip or the coupling could vibrate excessively.
