Grey metal jaw coupling hub with 16mm bore and keyway, 64mm diameter

Lovejoy

Lovejoy L099 16mm Jaw Coupling Hub

SKU CH-4WWY-77HP0

A 16 mm bore jaw coupling hub with 64 mm outside diameter and 73 mm overall length, rated to 7,000 RPM and compatible with L099 Buna-N, urethane or Hytrel spiders

  • 16 mm bore fits metric shafts directly
  • Carbon-steel hub withstands high-torque loads
  • 7,000 RPM rating suits high-speed drives
  • Set-screw locking secures hub without extra parts
  • Accepts Buna-N, Urethane or Hytrel spider elements

Coupling Hub for 16 mm Shafts

This jaw coupling hub fits a 16 mm round bore with a 5 mm keyway and 2.3 mm keyway depth. It is made from carbon steel and rated for up to 7,000 RPM. The hub suits metric shafting in general power-transmission applications.

Straight-Jaw Profile and Set-Screw Locking

The straight-jaw design accepts L099 Buna-N, Urethane or Hytrel centre elements for torque transmission. A set screw secures the hub to the shaft without clamping tools. At 64 mm outside diameter and 73 mm overall length, the hub installs in tight machine envelopes.

Interchangeable Centre Elements Alter Power Capacity

Swapping the spider changes the rating at 100 RPM: Buna-N gives 0.51 hp, Urethane 0.77 hp and Hytrel 1.3 hp. The hub ships alone, so the builder selects the element that matches the duty cycle. Buyers needing a complete coupling with spider included must source the centre element separately.

Questions about this item

What speed does the L099 16 mm hub cap at 7,000 RPM?

The hub is rated for a maximum speed of 7,000 RPM; above that the jaw coupling may exceed its design limits for safe operation.

What shaft and keyway dimensions does the 16 mm bore require?

The hub accepts a 16 mm round shaft with a 5 mm wide by 2.3 mm deep keyway for positive torque transmission.

How is the hub secured and which step is often missed?

Tighten the set screw over the keyway after aligning the hub; the common error is tightening on the shaft flats instead of the keyway slot.
