Disc Wheel Hub/Spoke Wheel and Axle Interface Dimensions - Truck and Bus
J1842_201402
This SAE Recommended Practice is intended for hubs and spoke wheels used on Class 6, 7, and 8 truck/truck-tractor non-powered front axles, powered and non-powered rear axles and trailer axles, for which bearing setting is manually adjusted. Assemblies using spacers to control bearing preload and endplay may differ in geometry and bearing componentry.
Rationale:
The document was revised to document hub/axle configurations in common use that were previously omitted and to remove configurations no longer in common use.
