Dimension Compatibility for Commercial Vehicle Wheels to Air Disc Brake Calipers - Truck and Bus
2020-06-05
CURRENT
J2803_202006
This SAE Recommended Practice defines the boundary line for establishing dimensional compatibility between air disc brake calipers and 22.5 x 8.25 inch disc wheels, including bent valve stems on steel wheels and manufacturer recommended valve stems on aluminum wheels. The line establishes the minimum wheel with valve stem envelope to allow interchangeability. The line does not accommodate customer-specific wheels (such as OEM-specific stylized wheels) or customer-specific brakes. This document addresses dimensional characteristics only and makes no reference to the performance, operational dynamic deflections or heat dissipation of the system. It is up to the system integrator to ensure sufficient clearance exists between the caliper, wheel and valve stem to provide safe operating conditions. Mounting systems as noted are referenced in SAE J694.

Identification of Truck, Trailer, and Bus Wheel Seals and Associated Packaging
2015-11-19
CURRENT
J2224_201511
This SAE Information Report lists the symbols used by suppliers of truck, trailer, and bus wheel seals to identify their products. These symbols appear on seals and packaging. 1.1 Purpose The purpose of this document is to provide users of truck, trailer, and bus wheel seals a means of identifying the suppliers of all such components by use of the symbology utilized by the suppliers on their components and packaging.

Disc Wheel and Hub or Drum Interface Dimensions - Truck and Bus
2021-04-30
CURRENT
J694_202104
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.

Wide Base Disc Wheels and Demountable Rims - Truck, Bus, and Trailer
2021-08-02
CURRENT
J876_202108
This SAE Recommended Practice establishes uniform engineering nomenclature for wide base disc wheels and demountable rims. This nomenclature and accompanying figures are intended to define fundamental wide base disc wheel and demountable rim terms. The dimensions given are those necessary to maintain serviceability and interchangeability of the wide base disc wheels and demountable rims with standard hardware. Valve clearances have not been included in this document.

Outboard Mounted Brake Drum/Disc Wheel Hub Interface Dimensions - Truck and Bus
2023-05-19
CURRENT
J1671_202305
This recommended practice contains dimensions and tolerances for outboard mounted brake drums and disc wheel hubs in the interface areas. This recommended practice is intended for outboard mounted brake drums and disc wheel hubs commonly used on class 7 and 8 commercial vehicles. Included are SAE J694 mounting systems II, III, IV, XIV, and X. Special and less common applications are not covered.

Dimensional Compatibility for Commercial Vehicles Fitment of Complete Wheels in Drum Brake Applications - Truck and Bus
2020-11-04
CURRENT
J1865_202011
This SAE Recommended Practice defines a clearance line for establishing dimensional compatibility between drum brakes and wheels with 19.5 inch, 22.5 inch, and 24.5 inch diameter rims. Wheels designed for use with drum brakes may not be suitable for disc brake applications. The lines provided establish the maximum envelope for brakes, including all clearances, and minimum envelope for complete wheels to allow for interchangeability. This document addresses the dimensional characteristics only, and makes no reference to the performance, operational dynamic deflections, or heat dissipation of the system. Valve clearances have not been included in the fitment lines. Bent valves may be required to clear brake drums. Disc brake applications may require additional running clearances beyond those provided by the minimum contour lines. Mounting systems as noted are referenced in SAE J694.
