Carbon steel jaw coupling hub, 14 mm bore, 54 mm diameter, 64 mm length

Lovejoy

Lovejoy L095 14 mm Jaw Coupling Hub

SKU CH-S3DX-GVX14

Carbon-steel jaw coupling hub with 14 mm keyed bore, 54 mm outside diameter and 64 mm overall length rated to 9,000 RPM

  • 14 mm bore fits standard metric shafts
  • 54 mm OD suits L095 series elements
  • Set-screw locking secures hub to shaft
  • Carbon-steel construction handles 9,000 RPM
  • Buna-N spider rated 0.31 hp at 100 RPM

14 mm Bore Jaw Coupling Hub

This Lovejoy L095 hub connects a 14 mm shaft using a set-screw lock and a 5 mm by 2.3 mm keyway. It is made from carbon steel and has an outside diameter of 54 mm with an overall length of 64 mm. The straight-jaw profile accepts L095 Buna-N, Urethane or Hytrel centre elements. It suits maintenance teams and OEM builders fitting metric shafting in general power-transmission drives.

Speed and Power Limits

The hub is rated to 9,000 rpm maximum. At 100 rpm it transmits 0.31 hp with a Buna-N spider, 0.47 hp with a Urethane spider and 0.89 hp with a Hytrel spider. Torque capacity scales linearly with speed, so higher-speed applications must stay within the horsepower figures shown. The set-screw locking method relies on shaft friction, so very high cyclic loads may require a different hub style.

Replaces Worn or Undersized Hubs

This hub replaces a damaged L095 hub of the same bore or upgrades from a smaller coupling size when the shaft diameter grows to 14 mm. The jump is worth it when the existing hub shows keyway wear, set-screw damage or when the drive torque exceeds the old hub's rating. It is not for shafts larger than 14 mm, for applications needing a clamp or keyless lock, or for non-L095 element series.

Highlights

  • 14 mm bore fits standard metric shafts
  • 54 mm OD suits L095 series elements
  • Set-screw locking secures hub to shaft
  • Carbon-steel construction handles 9,000 RPM

Questions about this item

Should I choose the Buna-N, Urethane or Hytrel spider for the L095 hub?

Buna-N gives 0.31 hp at 100 RPM, Urethane gives 0.47 hp and Hytrel gives 0.89 hp; pick the spider that matches your torque requirement.

What does the 9,000 RPM rating mean once the hub is mounted on a 14 mm shaft?

It is the maximum safe rotational speed for the hub itself; actual system speed will be limited by the spider, alignment and shaft balance.

How does the set-screw locking on the 14 mm bore affect installation?

The hub uses a set screw over a 5 mm keyway that is 2.3 mm deep; tighten the screw onto the key to prevent axial movement.
