Railway AAR Solid Wheel for Metro 

 
1. Description :

Our AAR Solid Wheel for Metro is engineered to solve exactly these problems. Manufactured in strict compliance with AAR M-107 and AAR M-208 standards, this solid rolled wheel delivers exceptional durability and reliability for subway, light rail, and intercity train applications.

Why do metro operators choose our AAR solid wheel?

• Proven compliance – Fully certified to AAR M-107/M-208, UIC, EN, and TB/T 2817 standards

• Extended service life – Surface hardness reaches 320–380 HB, significantly reducing tread wear and maintenance frequency

• Wide size range – Available in Φ500mm to Φ915mm diameters to fit diverse metro vehicle configurations

• Factory-direct pricing – Eliminate middlemen and secure competitive costs without compromising quality

2. Technical Specifications

Our railway solid wheel is available in multiple material grades to match your specific operating conditions:

Material grades explained:

• AAR-C – High-strength eutectoid steel offering excellent mechanical resistance combined with moderate toughness

• CL60 – Pearlitic steel with 0.55–0.65% carbon content, widely used in metro and passenger rail applications

• ER7/ER8/ER9 – European-standard grades with hardness ranging from 235 HB to 255 HB+

3. The AAR Solid Wheel Stand Out Points: 

Full AAR M-107/M-208 Certification – Every wheel undergoes rigorous testing including chemical analysis, ultrasonic testing (UT), magnetic particle testing (MT), mechanical property testing, and dimensional inspection.

High Wear & Peel Resistance – Our advanced heat treatment process (quenching and tempering) delivers a new metro wheel with superior wear resistance and strong peel resistance – critical for metro systems with frequent braking and tight curves.

Complete Traceability – From raw material melting to final machining, every production step is documented. Each wheel is marked with material grade, batch number, and manufacturer code for full lifecycle tracking.

Global Standards Compatibility – Beyond AAR, our solid wheels meet UIC, EN, BS, JIS, IRS, and TB standards, ensuring interchangeability across international rail networks.
