Product Features
1
OEM-Grade Forged Material & High Hardness Heat Treatment
The PC200 track roller is manufactured with premium 50MnB alloy steel via one-piece forging technology, strictly complying with Komatsu's OEM material standards for excavator undercarriage parts. The whole wheel body undergoes professional quenching and tempering heat treatment, achieving a surface hardness of HRC56-62 with a deep hardened layer of 8-12mm, which far exceeds the industry basic standard of HRC52-58. This high-strength material and heat treatment combination endows the roller with exceptional wear, extrusion and impact resistance, perfectly adapting to harsh working conditions like mines, construction sites and muddy land with gravel and rock.

Frequently Asked Questions
Q
What material is used for the PC200 track roller, and why does it matter?
The PC200 track roller is made from premium 50MnB alloy steel through one-piece forging technology. This material meets Komatsu's OEM standards and, combined with quenching and tempering heat treatment, achieves a surface hardness of HRC56-62 with a hardened layer of 8-12mm — significantly higher than the industry standard of HRC52-58. This ensures superior wear resistance, impact resistance, and long service life in harsh working environments.
Q
Which Komatsu excavator models is this track roller compatible with?
The PC200 track roller is compatible with all generations of Komatsu PC200 excavators, including PC200-5, PC200-6, PC200-7, and PC200-8, as well as the PC210 and PC220 series that share the same undercarriage system. It matches OEM part numbers 20Y-30-00012 and 20Y-30-00016.
Q
Is the PC200 track roller ISO certified?
Yes. All PC200 track rollers are manufactured in accordance with ISO international quality management system standards. Each unit undergoes strict inspection of sealing performance and rotation flexibility before leaving the factory, and the products are widely recognized in construction machinery markets across Europe, America, Southeast Asia, and the Middle East.
Q
What warranty is provided for the PC200 track roller?
We offer a 1-2 year warranty (up to 2,000 working hours) for all PC200 track rollers. This is significantly longer than the industry-average warranty of 6 months, reflecting our confidence in product durability and quality.
Q
Can this track roller withstand extreme working conditions such as mines or muddy terrain?
Absolutely. Thanks to the high-hardness heat treatment (HRC56-62) and forged 50MnB alloy steel construction, the PC200 track roller is engineered to handle demanding environments including mining sites, construction zones, and muddy or rocky terrain. Its deep hardened layer (8-12mm) provides excellent protection against extrusion and impact.
Q
How does the PC200 track roller compare to standard aftermarket products?
Unlike standard aftermarket track rollers that may only meet the basic HRC52-58 hardness standard, our PC200 track roller achieves HRC56-62 with a 8-12mm hardened depth. It is produced using OEM-grade forged material, ISO-certified processes, and strict dimensional consistency — making it a reliable, long-lasting replacement that performs at OEM level or above.
