Komatsu PC20 High Duty Forged Steel Excavator Track Carrier Roller with 40Mn2 Material and HRC52-58 Hardness

Carrier rollers used in heavy machinery undercarriages feature material selection tailored to working conditions, with common choices including 40Mn2, 40MnB, and 50Mn. These rollers undergo a rigorous manufacturing process:

• Precision forging followed by normalization
• Overall heat treatment
• Surface hardness of HRC52-60
• Hardened layer depth of over 7-10mm (HRC45)

Equipped with high-quality floating seals and a reliable lubricating system, our track and carrier rollers adapt seamlessly to diverse climates and temperatures. They operate stably under severe working conditions or extreme temperatures ranging from -45℃ to 120℃, while keeping the components maintenance-free.

Our carrier rollers are meticulously crafted using high-strength alloy steel and advanced hot-forging techniques, ensuring unparalleled durability and longevity. Designed with robustness in mind, they withstand extreme loads and impacts, making them ideal for challenging construction and mining applications.

Through rigorous design processes with emphasis on precision, our carrier rollers achieve optimal structure that ensures flawless track alignment. This innovative design dramatically reduces friction and wear, extending the lifespan of your undercarriage components by an impressive 40% compared to traditional models.

The advanced design reduces friction and wear, resulting in fewer replacements, lower maintenance costs, and enhanced worksite productivity.
