Jaw Coupling Hub Stainless Steel 1-1/8 in

This stainless steel jaw coupling hub fits a 1-1/8 inch round bore with a keyway. It uses a set screw locking method to secure the shaft. The component is designed for power transmission applications requiring corrosion-resistant materials.

Coupling Size L100 Capacity

The hub is rated for a maximum speed of 7,000 RPM. Horsepower at 100 RPM varies by spider material: 0.66 hp with Buna-N, 1 hp with urethane, and 1.8 hp with Hytrel. It accepts compatible center elements L100H, L100N, and L100U.

Questions about this item

Will this 1-1/8 in bore hub fit the 2 17/32 in OD coupling on my existing L100 shaft?

Yes, the hub is sized for L100 couplings with a 2 17/32 in outside diameter and a 1-1/8 in bore with 1/4 in keyway.

How can I verify the 7,000 RPM rating after installing the set-screw hub?

Run the shaft up to speed and check for vibration or overheating; smooth operation at rated RPM confirms the hub and spider are aligned.

Does the box include the L100 spider or only the stainless-steel hub with set screws?

Only the stainless-steel hub with set screws is supplied; the L100 Buna-N, Urethane or Hytrel spider must be purchased separately.
