    E312 Track Roller, E312 bottom roller, CAT E312 Lower Roller
    50Mn/40Mn2 track rollers are durable, high-strength undercarriage components for excavators and bulldozers, commonly manufactured through casting or forging. Featuring high toughness and hardness (typically HRC 52-58), these rollers are designed to withstand heavy loads and wear in demanding construction and mining environments, often offering a 2000-hour warranty. 
    Key Features and Specifications: 
    • Material: 50Mn (high-quality carbon steel) or 40Mn2 (manganese steel), both offering excellent wear resistance.
    • Process: Manufactured via precision casting or forging for enhanced structural integrity.
    • Surface Hardness: Heat-treated to HRC 52-58 to resist wear and fatigue.
    • Compatibility: Suitable for various machinery, including [Liebherr R944/R954] and [Caterpillar D8R/D475] models.
    • Types: Available in single flange and double flange designs.
    • Colors: Generally available in black or yellow finish. 
    These rollers are critical for maintaining smooth tracked vehicle operation and reducing maintenance downtime in industrial applications.
