Aluminium jaw coupling hub with clamp-on bore and keyway

Ruland Manufacturing

Ruland Manufacturing JCC26-10-A Jaw Coupling Hub 5/8 in Bore

SKU CH-XDRZ-YPG61

Aluminum jaw coupling hub with 5/8 in bore, clamp-on locking, and 8,000 RPM rating

  • Clamp-on locking secures shaft without marring
  • 5/8 inch bore with keyway fits standard shafts
  • Aluminium hub reduces rotating mass
  • Curved jaw profile allows angular misalignment
  • 8,000 RPM rating suits high-speed drives

Jaw Coupling Hub 5/8 in Bore

The Ruland Manufacturing JCC26-10-A is an aluminium jaw coupling hub designed for power transmission applications. It features a 5/8 in bore diameter with a keyway and clamp-on shaft locking for secure attachment. The hub suits machinery requiring a Size JC26 coupling component.

Curved Jaw Profile and Fail-Safe Design

The curved jaw profile works with a compatible spider to dampen vibration and accommodate misalignment. A fail-safe feature ensures continued operation if the elastomer element fails. Full bearing support is required for proper installation and performance.

Suits Inch-Shaft Builds Needing Clamp Mounting

This hub fits 5/8 in shafts with a 3/16 in keyway width and M4 screw threads. It is not for metric shafts, keyless connections, or set-screw locking methods. Builders needing different bore sizes or coupling series should look at other models.

Highlights

  • Clamp-on locking secures shaft without marring
  • 5/8 inch bore with keyway fits standard shafts
  • Aluminium hub reduces rotating mass
  • Curved jaw profile allows angular misalignment
  • 8,000 RPM rating suits high-speed drives

Questions about this item

Will the aluminum hub or the elastomer spider need replacement first under normal use?

The aluminum hub resists wear, but the elastomer spider — sold separately — absorbs shock and misalignment and is the component that degrades over time.

At 8 000 RPM what limits continuous operation — speed rating or heat buildup?

The 8 000 RPM rating is the mechanical speed limit; sustained operation near that speed can generate heat in the spider, so monitor hub temperature during long runs.

How much noise and vibration should I expect from the clamp-on hub running all day?

The curved jaw profile and clamp-on bore reduce backlash, so vibration stays low; noise is mainly a faint hum from the spider mesh under load.
