222-7251 Ring is a Caterpillar hardened steel component used with the speed sensor in the wheel and final drive group. Featuring 57 internal spline teeth and 48 external sensor teeth, it supports reliable rotational speed detection and final-drive operation on CAT 793D, 793F and 793F CMD mining trucks.
Final Drive Speed Sensor Ring: 222-7251 is designed for use with the speed sensor within the wheel and final drive assembly.
Hardened Steel Construction: The hardened steel construction helps improve durability and resistance to spline wear during heavy-duty operation.
57 Internal Spline Teeth: The internal spline configuration provides secure engagement with the corresponding final-drive components.
48 External Sensor Teeth: The external teeth interface with the speed-sensing system to support accurate rotational speed detection.
Reliable Rotational Feedback: The ring works as part of the speed sensor system to provide rotational information required by the machine control system.
Heavy-Duty Drivetrain Application: Designed for the wheel and final drive assembly of large Caterpillar mining trucks.
Replacement Solution: Suitable for replacing a worn or damaged ring during final-drive inspection, repair or overhaul.
