The XS250P Pin For PC3000 is a heavy-duty connection component designed for KOMATSU PC3000 excavators—a 300-ton class machine deployed in large-scale mining and bulk material handling. This pin forms the critical pivot point between the excavator’s superstructure and undercarriage, supporting rotational movements while bearing the machine’s full weight during slewing operations.
Extra-Thick Construction: With a 250mm diameter and 800mm length, the pin is forged from SNC815 nickel-chromium steel, undergoing a 48-hour normalization process to relieve internal stresses.
Advanced Heat Treatment: Double tempering at 620°C ensures a yield strength of 850MPa, enabling the pin to withstand static loads exceeding 5,000 kN during machine transport.
Precision Tolerances: Machined using CNC grinding centers, the pin achieves a cylindricity error of ≤0.03mm/m, ensuring uniform load distribution across the bearing surface.
Corrosion-Resistant Coating: A duplex coating system (zinc phosphate + epoxy primer) provides protection against acidic mine water and industrial pollutants, extending service life in aggressive environments.
KOMATSU PC3000-6: Critical to the upper structure slewing joint, enabling 360° rotation while supporting the boom and counterweight assembly.
Mining and Quarrying: Essential for hard rock excavation in iron ore and coal mines, compatible with 10m³-12m³ heavy-duty buckets.
Large-Scale Earthmoving: Used in port development projects, facilitating bulk material handling in stockyards and ship loading operations.
