Disc Wheel and Hub or Drum Interface Dimensions - Truck and Bus
This SAE Recommended Practice contains dimensions and their tolerances concerning disc wheel to hub or drum interface areas for truck and bus applications. Disc wheels designed only for single wheel applications (not dual wheels) for light trucks and special or less common applications are not covered in this document.
Rationale: The use of sleeved 2pc flange nuts has been increasing in the NA market over the past 5-10 years. The J694 was determined by the committee to be the most logical place to address the usage of sleeved 2pc flange nuts. The goal will be to produce a recommended practice for the usage of sleeved 2pc flange nuts for truck and bus application.
