AMR2219N
Meritor AM Rotor EX225
Bendix

This rotor is optimized for use with an EX225 caliper assembly, delivering balanced friction performance and reliable heat dissipation in demanding trucking environments. The 434 mm diameter provides ample moment arm for high braking torque, while the 143.30 mm height maintains a compact footprint compatible with common wheel-end packages. The EX225 caliper integration supports strong clamping efficiency and consistent pad contact, which helps extend pad life and reduce rotor wear under heavy stop-and-go or sustained descending routes. The VMRS code 013-017-001 classifies this part as a rotor assembly within the brake system, aiding maintenance planning and parts indexing. Its inclusion in the 41378 category situates it among the rotor family designed for commercial vehicles with robust axle and hub interfaces. The absence of cross references indicates a direct-fit approach to replacement, simplifying stocking and installation. In service, operators will notice stable braking response, reduced fade during repeated stops, and dependable performance in fleet applications that require dependable ring geometry, heat tolerance, and repeatable wear characteristics across a wide operating envelope.
