SKU CH-R2MQ-X6X48

Connects 24 mm shafts with a 54 mm carbon-steel hub rated to 9 000 RPM and compatible with Buna-N, Urethane or Hytrel centre elements

  • 24 mm bore fits standard metric shafts
  • 54 mm outside diameter for compact installations
  • 9,000 RPM maximum speed supports high-speed drives
  • Carbon steel hub resists wear under torque
  • Set-screw locking secures hub without additional hardware

24 mm Bore Jaw Coupling Hub

The Lovejoy L090 hub fits a 24 mm shaft and uses a set-screw locking method with an 8 mm keyway that is 3.3 mm deep. Its carbon-steel body measures 54 mm in outside diameter and overall length, and it is rated for speeds up to 9 000 RPM.

Suits metric shaft connections needing L090 elements

This hub works with L090H, L090N and L090U centre elements and transmits 0.23 hp at 100 RPM with a Buna-N spider, 0.35 hp with urethane or 0.64 hp with Hytrel. It is not for inch-dimension bores, clamp-style locking or coupling sizes other than L090.

Check shaft size, keyway and element compatibility

Verify that the driven shaft is exactly 24 mm round with an 8 mm keyway before ordering. Confirm the required spider material for your torque load and ensure the 54 mm outside diameter clears adjacent components in your assembly.
