The XS145P Pin For PC2000 is a specialized connection component engineered exclusively for KOMATSU PC2000 excavators—a 200-ton class machine widely used in large-scale mining and infrastructure projects. This pin serves as a critical load-bearing element in the main boom-to-arm connection, transmitting hydraulic forces between structural components while maintaining joint stability under extreme operational stress.
Robust Design: Forged from SCM440 alloy steel (equivalent to AISI 4140), the pin undergoes ultrasonic testing to eliminate internal defects, ensuring uniform strength across its 145mm diameter cross-section.
Enhanced Lubrication Channels: Four circumferential oil grooves with 3mm depth and 12mm spacing distribute grease evenly across the pin surface, reducing friction coefficient to 0.08 and extending maintenance intervals by 500 operating hours.
Precision Fit: Machined to IT5 tolerance standards, the pin achieves a clearance of 0.05-0.12mm with mating bushings, eliminating excessive play that could cause structural vibration.
Wear-Resistant Coating: A 0.2mm thick chrome plating with a hardness of 850HV forms a protective layer, reducing wear rate by 30% compared to uncoated steel in abrasive environments.
KOMATSU PC2000-8: Integral to the boom-to-arm pivot joint, supporting dynamic loads up to 1,200 kN during digging and lifting operations.
Mining Operations: Essential for overburden removal and ore extraction in open-pit mines, compatible with 5m³-8m³ bucket attachments.
Infrastructure Projects: Used in dam construction and tunnel excavation, where the PC2000’s high breakout force requires reliable joint performance.
