Description / Abstract:

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.


The purpose of this document is to establish dimensional guidelines to promote functional standardization of wheel hubs and spoke wheels in the areas of fasteners, bearing cup, seal bore and axle drive shaft interface or hubcap attachment. This document is not intended to exclude use of wheel hub designs, which do not meet the dimensional guidelines for use on defined axle configurations.
