AMR2237N
Meritor AM Rotor EX225
Bendix

With an EX225 caliper interface, this rotor matches a 434 mm diameter and 45 mm thickness to deliver high-speed stopping capability within a slim rotor profile. The design preserves robust heat management while maintaining compatibility with tight wheel-end envelopes common in modern heavy-duty tractors and trailers. The EX225 clamping characteristics help achieve consistent pad contact across a wide temperature range, supporting longer pad life and lower maintenance frequency under demanding duty cycles. VMRS 013-017-001 places this part in the rotor assembly family for strategic maintenance planning, and category 41378 confirms its role within the rotor lineup designed for common axle and hub configurations. The absence of cross references means fleets can source and replace based on this specification without navigating alternative part references, ensuring predictable performance and simpler inventory management in the field.
