The XS40P Pin is a versatile mid-size connection component designed for KOMATSU mid-range excavators (30-40 ton class), balancing structural strength with weight efficiency. This pin is commonly used in secondary linkage systems, providing secure articulation between hydraulic cylinders and moving structural parts in both standard and long-reach configurations.
Optimal Strength-to-Weight Ratio: Cold-drawn from 42CrMo steel with a tensile strength of 900MPa, the pin achieves a 15% weight reduction compared to forged alternatives without compromising load capacity.
Surface Hardening: The pin’s outer layer undergoes induction hardening to 58-62 HRC, creating a wear-resistant shell (0.5-1mm depth) while maintaining a ductile core to absorb impact loads.
Standardized Dimensions: Conforms to KOMATSU’s JIS B 8803 specification, ensuring interchangeability with original equipment pins across PC300-8, PC360LC-11, and PC400-7 models.
Cost-Effective: Batch production via automated machining reduces manufacturing costs, making it a budget-friendly option for fleet maintenance programs.
KOMATSU PC300, PC360 Series: Used in stick cylinder rod ends and bucket linkage pins, supporting loads up to 450 kN.
General Construction: Ideal for road building and urban development projects, compatible with tiltrotator attachments for precision grading.
Agricultural and Forestry: Facilitates excavator use in land reclamation and tree harvesting, withstanding debris impact and seasonal temperature variations.
