  • Sintered iron hub withstands heavy torque loads

Shaft Coupler Hub L095

The Dayton 29HY90 is a sintered iron jaw coupling hub with a one inch bore and a quarter inch keyway. It fits L095 size couplings and uses a set screw for shaft locking. The straight jaw profile accepts compatible Buna-N, urethane or Hytrel center elements.

Replaces Worn L095 Hubs

Install this hub when an existing L095 coupling shows wear on the bore or keyway. The jump is worth it if your application runs up to nine thousand RPM and requires the horsepower ratings listed for the chosen spider material at one hundred RPM.

Verify Shaft And Spider Before Ordering

Confirm the shaft diameter is exactly one inch and that the keyway dimensions match a quarter inch width by one eighth inch depth. Ensure the center element part number is L095H, L095N or L095U for proper jaw engagement.

Questions about this item

What bore diameter and keyway dimensions does the L095 hub require on the shaft?

The hub accepts a 1 in round bore with a 1/4 in wide by 1/8 in deep keyway.

How do the set screws lock the hub, and what step is often missed?

Tighten both set screws against the key and shaft flats; the common error is securing only one screw.

Which centre element part numbers are compatible, and how does the spider material change the power rating at 100 RPM?

Use L095H, L095N or L095U; Buna-N gives 0.31 hp, urethane 0.47 hp, Hytrel 0.89 hp at 100 RPM.
