Scope:

This SAE Recommended Practice is intended for hubs and spoke wheels used on Class 7 and 8 truck/truck-tractor nonpowered front axles, powered and nonpowered rear axles, and trailer axles.

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

Rationale:

The objective of this revision is to restablish standardization within the interface areas of the drive flange and hubs or spoke wheels to ensure proper assembly. This revision will define and document the dimensions and tolerances necssary to maintain interchangeability in the interface area. There is a need within the industry to a recommended dimensional standard. Proper assembly may not be possible, without adherence to this standard.
