Scope:

This recommended practice contains dimensions and tolerances for spindles in the interface area. Interfacing components include axle spindle, bearing cones, bearing spacer, seal and wheel hub. This recommended practice is intended for axles commonly used on Class 7 and 8 commercial vehicles. Included are SAE axle configurations FF, FL, I80, L, U, W, R, N and P.

Rationale:

The objective of this document is to establish dimensional standardization within the interface areas of the axle spindle, bearing cones, bearing spacer, seal, and wheel hub. This dimensional standardization will assure no interference conditions exist for mating components.

This recommended practice will define and document the dimensions and tolerances necessary to maintain serviceability and interchangeability in the interface areas. There is a need within the industry for a recommended dimensional standard, since without it, improper mating of spacers, spindles and hub may occur.
