Coupling Hub for L075 Spider

This Dayton jaw coupling hub accepts a 1/2 inch round bore and uses a set screw with 1/4-20 UNC threads to lock onto the shaft. The sintered iron body carries the L075 coupling size and a straight jaw profile. It is built for power transmission assemblies that require a removable hub on one side of the spider.

Fits L075 Buna-N, Urethane or Hytrel Elements

The hub matches centre elements with manufacturer part numbers L075H, L075N and L075U, letting the builder choose the spider material for the application. An outside diameter of 1 3/4 inches and an overall length of 2 1/8 inches define the space the hub occupies in the driveline. No additional clamping hardware is required beyond the integral set screw.

Rated to 11,000 RPM with Three Power Options

At 100 RPM the hub transmits 0.14 hp with a Buna-N spider, 0.21 hp with a Urethane spider and 0.36 hp with a Hytrel spider. The sintered iron construction handles the rated speed without added lubrication. Buyers needing higher torque capacity or a different bore size cannot use this hub.

Questions about this item

Will the 11,000 RPM limit be reached before the coupling overheats?

The hub is rated for 11,000 RPM maximum speed; thermal limits depend on the spider material and actual torque load rather than speed alone.

How much heat or noise does the sintered iron hub generate during continuous operation?

The hub itself produces minimal noise and heat; most vibration and temperature rise come from the flexible spider element under load.

Which L075 spider must I already have to use this 1/2 in bore hub?

This hub accepts L075H, L075N or L075U center elements; choose Buna-N, Urethane or Hytrel based on the horsepower you need at 100 RPM.
