Climax Metal Products 2ISCC-112-100KW Rigid Shaft Coupling Collectible

SKU CH-2EZG-5EF93

A rigid carbon-steel shaft coupling joins 1 1/8 in and 1 in keyed bores with a 3 1/8 in overall length, rated for 4,000 RPM and 2,470 in-lb torque

  • TypeBearings, V-belts & Power Transmission Equipment
  • ColorTransparent
  • Precision fit with two bores sized 1 in and 1 1/8 in
  • Two-piece carbon-steel construction for rigid torque transfer
  • Rated to 4,000 RPM and 2,470 in-lb maximum torque
  • Compact 3 1/8 in overall length suits tight installations
  • Keyed round bores with 1/4 in and 1/8 in keyway widths prevent slippage

Two-Piece Rigid Shaft Coupling

This coupling connects two shafts with different bore diameters in a fixed, zero-backlash joint. It suits maintenance teams and machinery builders who need a simple, permanent alignment between a 1 in shaft and a 1 1/8 in keyed shaft. The carbon-steel construction and two-piece clamp design allow installation without moving adjacent components.

Sustained Load Behaviour

Rated for 2,470 in-lb maximum torque and 4,000 RPM maximum speed, the coupling transmits power continuously within those limits. The rigid carbon-steel body does not absorb vibration or compensate for misalignment, so shaft alignment must remain precise throughout the duty cycle to avoid premature bearing wear.

Interface Practical Limits

The 1 7/8 in outside diameter and 2.19 in clearance diameter set the minimum space envelope around the joint. The keyway dimensions of 1/4 in width by 1/8 in depth on each bore define the key stock required. Operation beyond the stated torque or speed ratings will exceed the material capacity of this carbon-steel coupling.

Questions about this item

How much heat and noise does the 2ISCC-112-100KW coupling generate when running continuously at 4,000 RPM?

The rigid carbon-steel coupling has no moving internal parts, so it produces negligible heat and runs silently; only the connected shafts and bearings generate measurable temperature rise or noise.

What shaft diameters and keyway dimensions must my existing shafts match for the 2ISCC-112-100KW to fit?

One shaft must be 1 1/8 in with a 1/4 in keyway width and 1/8 in keyway depth; the other shaft must be 1 in with a 1/4 in keyway width and 1/8 in keyway depth.

Will the 2ISCC-112-100KW coupling align with older equipment that uses a 2.19 in clearance diameter and 3 1/8 in overall length?

Yes — the coupling’s 2.19 in clearance diameter and 3 1/8 in overall length match those dimensions, so it fits the same mounting envelope as legacy units with those specs.
