Small aluminium jaw coupling hub with clamp screw and 6 mm bore

Ruland Manufacturing

Ruland Manufacturing MJC15-6-A Jaw Coupling Hub 6 mm Bore

SKU CH-ZPYH-YXCCQ

A 6 mm bore jaw coupling hub with 15.1 mm outside diameter and 21.8 mm overall length, clamp-on locking for metric shafts up to 8,000 RPM

  • Precision fit with 6 mm bore and +0.05/-0.00 mm tolerance
  • Secure clamping via M2 screw on curved jaw profile
  • High-speed rating up to 8,000 RPM for demanding drives
  • Lightweight aluminium hub with 15.1 mm outer diameter
  • Fail-safe jaw design ensures continued operation if spider fails

Jaw Coupling Hub MJC15 6 mm Bore

This jaw coupling hub is sized MJC15 with a 6 mm round bore and clamp-on shaft locking. It is manufactured from aluminium and rated to a maximum speed of 8,000 RPM for metric power-transmission systems. The curved jaw profile provides fail-safe operation when paired with a compatible spider.

Suits Metric Shafts With Clamp Mounting

This hub fits 6 mm metric shafts that require a clamp-style connection without a keyway. It is not intended for inch-dimension shafts, keyed bores or set-screw locking methods. Applications needing a larger bore diameter or a different coupling size will require another hub.

Critical Specification: 6 mm Bore With Clamp Lock

The 6 mm bore diameter combined with the M2 clamp screw defines whether this hub matches the driven shaft. Verify the shaft tolerance of +0.000/-0.013 mm and the bore tolerance of +0.05/-0.00 mm before installation.

Highlights

  • Precision fit with 6 mm bore and +0.05/-0.00 mm tolerance
  • Secure clamping via M2 screw on curved jaw profile
  • High-speed rating up to 8,000 RPM for demanding drives
  • Lightweight aluminium hub with 15.1 mm outer diameter
  • Fail-safe jaw design ensures continued operation if spider fails

Questions about this item

What is the maximum continuous speed of the MJC15 hub before it becomes the limiting factor?

The hub is rated for a maximum speed of 8,000 RPM, which is the primary limit under sustained operation.

How much heat or noise does the aluminium hub generate during all-day operation at high speed?

The aluminium hub itself produces negligible heat and no audible noise; thermal and acoustic load comes from the driven components and the elastomer spider.

Which shaft diameter and tolerance must the existing shaft meet for the clamp-on bore to lock securely?

The hub requires a 6 mm round shaft with a tolerance of +0.000/-0.013 mm for the clamp-on bore to achieve full holding force.
