SAE J1730:2019 pdf free.ABS Exciter Ring Location Standardization
This SAE Recommended Practice establishes the Antilock Brake System [ABS] sensor interface and envelope dimensions for standardizing the location of the ABS rings mounted on the inner end of spoke wheels, hubs and hub-rotor assemblies on the following axle designations.
This document provides standardized wheel end ABS sensor interface dimensions for spoke wheels, hubs, and hub-rotor assemblies intended for normal highway use on trucks, buses, truck trailers and multi-purpose vehicles. The ilustrations given in the document are for reference only. These ilustrations show typical sensor ring designs and mountings, but are not limited to those shown. Serviceability considerations are not covered in this document.
The following publications are provided for information purposes only and are not a required part of this SAE Technical Report.

SAE J393 Nomenclature – Wheels, Hubs, and Rims for Commercial Vehicles
SAE J1842 Disc Wheel Hub/Spoke Wheel and Axle Interface Dimensions – Truck and Bus
SAE J2475 Wheel End Assembly and Axle Spindle Interface Dimensions – Truck and Bus
A listing of the basic nomenclature and definitions is shown as follows. A hub shall be defined as a disc wheel hub or the hub area of a spoke wheel. A hub/rotor assembly shall be defined as the combination of a hub and rotor. The rotor may be attached to the hub with a variety of techniques (i.e., bolted, retained with a stud and nut).
See Figures 1 to 12 and Tables 1 to 3.
a. A= Outer bearing cup (per American Bearing Manufacturers Association)
b. B = Inner bearing cup (per American Bearing Manufacturers Association)
c. C = Wheel speed sensor
d. D= 7 mm diameter sensor target zone
e. E = Dimension from inner bearing cup seat to the face of the ABS exciter ring teeth
f. F = Minimum inside diameter of the ABS exciter ring to allow for seal clearance
g. G= Basic sensor pitch diameter
h. H = Maximum outside diameter of the ABS tone ring.SAE J1730 pdf free download.
