Jaw Coupling Hub L110 3/4 in Bore
This Dayton jaw coupling hub fits a 3/4 inch round bore with a standard keyway for inch-series shaft connections. It is designed for power-transmission assemblies that use an L110 spider element to join two shafts while accommodating slight misalignment.
Set Screw Locking Straight Jaw Profile
The hub uses a set-screw locking method on a straight jaw profile, so installation requires only common hand tools and proper key alignment in the 3/16 inch wide by 3/32 inch deep keyway. Misaligned key seating or over-tightened set screws are the most common causes of vibration or premature spider wear.
Sintered Iron 5000 RPM Limit
Sintered iron construction limits the hub to a maximum speed of 5 000 RPM and transmits up to 1.3 hp at 100 RPM with a Buna-N spider, 2.0 hp with urethane, or 3.6 hp with Hytrel. Builders needing higher speeds or torque capacities must select a larger coupling size or different hub material.
