SKU CH-PW3N-YQB0K

  • 22 mm bore fits metric shafts directly
  • Carbon-steel hub rated to 5 000 RPM
  • 3 hp @ 100 RPM with Buna-N spider
  • 85 mm OD matches L110 spider elements

L110 Jaw Coupling Hub, 22 mm Bore

This carbon-steel hub fits L110 jaw couplings and accepts a 22 mm shaft with a 6 mm keyway and 2.8 mm keyway depth. It uses a set-screw locking method and a straight jaw profile for direct drive connections. The overall length is 107 mm and the outside diameter is 85 mm. Maximum rated speed is 5,000 RPM.

Replaces Worn L110 Hubs on Existing Shafts

Install this hub when the original L110 hub shows keyway wear, set-screw damage or corrosion that prevents reliable torque transfer. The jump is worth it when the spider element remains serviceable but the hub bore or keyway no longer grips the shaft securely. Compatible centre elements are L110H, L110N and L110U.

Set-Screw Install, Check Key Fit First

Slide the hub onto the 22 mm shaft, align the 6 mm keyway, and tighten the set screw over the key. The most common issue is a loose key fit that allows micro-movement and fretting; verify the key seats fully before final torque. Ensure the spider element matches the hub jaw profile before assembly.

Questions about this item

What shaft diameter and keyway dimensions does the 22 mm bore accept?

The hub has a 22 mm round bore with a 6 mm keyway width and 2.8 mm keyway depth for standard metric keyed shafts.

How is the hub secured to the shaft, and what is the common installation mistake?

Two set screws lock the hub; the frequent error is tightening them before fully seating the hub and aligning the key, which can mar the shaft or leave the key loose.

Which centre element part numbers are compatible for future replacement?

The hub works with L110H, L110N and L110U centre elements, covering Hytrel, Buna-N and urethane spider options.
