  • Carbon steel hub handles up to 7 000 RPM
  • Set-screw locking secures the hub to the shaft

L099 Jaw Coupling Hub for 19 mm Shafts

This L099 jaw coupling hub fits a 19 mm round bore with a 6 mm keyway and 2.8 mm keyway depth. It is made from carbon steel and uses a set-screw locking method. The hub accepts L099H, L099N or L099U centre elements for power transmission applications.

Replaces Worn or Mismatched Hubs on L099 Couplings

The hub directly replaces an existing L099 hub when the bore size or keyway no longer matches the shaft. The upgrade is worth it when a 19 mm bore with metric keyway is required instead of a different bore diameter or imperial keyway configuration.

Fits Standard L099 Elements in Metric Drivelines

The hub has a 64 mm outside diameter and 73 mm overall length, designed for metric system drives. It requires a compatible L099 spider element to complete the coupling assembly. It frees the designer from sourcing custom bore sizes by providing a standard 19 mm metric bore option.
