  • Carbon steel hub withstands 5,000 RPM maximum operating speed
  • 1-inch round bore with 1/4-inch keyway fits standard shafts
  • Set screw locking secures hub without additional hardware
  • Compatible with L190 Buna-N, Urethane and Hytrel center elements

Application & Fit

The Dayton 29HY60 is a jaw coupling hub built for power-transmission systems that use an L190 centre element. It accepts a 1-inch round shaft with a standard keyway and secures it with a set-screw locking method. The carbon-steel body suits industrial machinery where a straight-jaw profile is specified. Buyers needing a different bore size or a clamp-style hub will need another part.

Thermals Noise Power

As a purely mechanical component the hub generates no electrical noise and has no power draw of its own. Operating temperature is dictated by the surrounding drivetrain and the chosen spider material. The supplier rates maximum rotational speed at 5,000 RPM, so thermal limits follow the spider selection and lubrication regime rather than the hub itself.

Deciding Specification

The critical figure is the horsepower rating at 100 RPM, which changes with the spider compound: 2.7 hp with Buna-N, 4.1 hp with urethane and 7.4 hp with Hytrel. Match the spider to the application torque requirement; the hub itself does not alter these limits.

Questions about this item

How do I install the Dayton 29HY60 hub on a 1 inch shaft and which step is often missed?

Slide the hub onto the shaft, align the 1/4 inch keyway with the shaft key, then tighten the set screw over the key — the step often missed is confirming the key is fully seated before locking the screw.

What replacement centre element will this L190 hub need and how do I choose the right spider?

Use part numbers L190H for Hytrel, L190N for Buna-N or L190U for urethane; match the spider to your torque and temperature requirements.

At 5,000 RPM continuous, which limit appears first — speed rating or horsepower capacity?

The 5,000 RPM maximum speed is the hard limit; horsepower ratings of 2.7 hp (Buna-N), 4.1 hp (urethane) or 7.4 hp (Hytrel) are given at 100 RPM and drop at higher speeds.
