Small cylindrical metal coupling with two different bore sizes

Climax Metal Products

Climax Metal Products ISCC-062-050 Rigid Shaft Coupling

SKU CH-4DVB-R3HCG

Connects two shafts with 1.56 in clearance and handles up to 710 in-lb of torque

  • MaterialHAWA
  • One-piece carbon-steel body simplifies installation
  • Handles up to 710 in-lb torque for reliable power transmission
  • Rated to 4,000 RPM for high-speed applications
  • Accommodates different bore sizes from 1/2 in to 5/8 in
  • 56 in clearance diameter fits compact spaces

Rigid Shaft Coupling ISCC-062-050

This one-piece carbon steel coupling joins two round shafts with different bore sizes of 1 5/8 in and 1/2 in. It suits light industrial drives where a solid, backlash-free connection is needed. The compact 2 in overall length fits tight machine envelopes. Maximum operating speed is 4, 000 RPM.

Capacity and Headroom

Rated torque reaches 710 in-lb, giving comfortable headroom for small conveyors, pumps or gearboxes running well below that limit. The 1.56 in clearance diameter keeps the profile slim. At speeds approaching the 4, 000 RPM ceiling or torques near 710 in-lb, a larger coupling or a flexible alternative should be considered.

Upgrade Path

Replaces two-piece clamp couplings or set-screw hubs that can loosen under vibration. The jump is worth it when alignment is already precise and zero backlash is required. Not suited for applications needing misalignment compensation, axial float or keyway engagement.

Questions about this item

Will the 1 5/8 in bore mate with my existing 1/2 in shaft?

The coupling has a minimum bore of 1/2 in and a maximum of 5/8 in, so a 1/2 in shaft fits within the range.

How can I confirm the 4 000 RPM limit is not exceeded once installed?

Use a tachometer on the driven shaft during operation; the coupling is rated for up to 4 000 RPM continuous speed.

Does the box include set screws or keys for the 1.56 in clearance diameter?

The coupling is a one-piece carbon steel unit with no keyways; it transmits torque through friction fit alone.
