Jaw Coupling Hub for L190 Elements

The Dayton 29HY65 is a carbon-steel hub designed to accept L190 Buna-N, Urethane or Hytrel centre elements in power-transmission assemblies. It fits a 1-5/8 inch round shaft with a 3/8 inch wide by 3/16 inch deep keyway and secures with a set screw.

Decisive Specification — Bore and Keyway

The hub only works when the driven shaft matches the 1-5/8 inch bore diameter and the 3/8 inch by 3/16 inch keyway dimensions exactly; any other shaft size or key profile will prevent installation.

Thermal Noise and Power Characteristics

The assembly is rated for continuous operation at up to 5 000 RPM with transmitted power of 2.7 hp at 100 RPM using a Buna-N spider, 4.1 hp with Urethane and 7.4 hp with Hytrel. No active cooling or lubrication is required in normal service.
