Companion Flanges, Type A (External Pilot) and Type S (Internal Pilot)
2016-01-26
CURRENT
J1946_201601
This SAE Standard specifies the nominal dimensions and tolerances which affect the interchangeability between companion flanges and mating parts. The flanges covered by this document are designated type A and type S. The type A flanges are equivalent to type A ISO 7646. The type S flanges are equivalent to the type S ISO 7647. Type A is an external (male) pilot construction and type S is an internal (female) pilot construction. These flanges are not interchangeable. Dimensions not specified are left to the discretion of the component manufacturer.

CURRENT
J3218_202209
This SAE Recommended Practice covers beam axles utilizing hypoid gear final drives. It is a component level test, performed with three dynamometers in a “T-cell” arrangement. It includes both an efficiency characterization method, as well as a break-in method to support efficiency characterization. It was developed for beam axles used in light truck applications but may be extended to other hypoid gear drive systems.
