Dayton L095 Jaw Coupling Hub 1/2 in Bore

The Dayton 29HY98 is a sintered iron jaw coupling hub designed for inch-series power transmission systems. It accepts a 1/2 inch round bore shaft secured by a 5/16-18 UNC set screw and matches L095 centre elements. This hub suits maintenance teams and OEM builders replacing worn hubs on light-duty drives.

Upgrade from worn or undersized hubs

Replace a damaged L095 hub when shaft fit has loosened or jaw faces show deformation. The jump is worth it when the existing hub no longer transmits rated torque or when a different bore size is required for a new motor shaft. Buyers needing a larger bore or a clamp-style lock will need a different hub model.

Practical limits of the L095 interface

The L095 size caps rated horsepower at 0.31 hp with Buna-N spider, 0.47 hp with urethane spider and 0.89 hp with Hytrel spider at 100 RPM. Maximum rotational speed is 9,000 RPM. Outside diameter is 2 7/64 in and overall length is 2 1/2 in. Only compatible centre elements are L095H, L095N and L095U.

Questions about this item

What shaft diameter fits the 1/2 in bore on this L095 hub?

The hub accepts a 1/2 in round shaft and is secured with a 5/16-18 UNC set screw.

Which step is often missed when installing the set screw on this sintered iron hub?

Align the set screw over the keyway or flat on the shaft, then torque the 5/16-18 UNC screw to the manufacturer's specification so the hub cannot walk.

When should the L095 spider element be replaced on this coupling?

Replace the spider when vibration increases, the jaws show wear, or the element cracks; compatible spares are L095H, L095N and L095U.
