Grade 12.9 High Tensile Strength: Manufactured from premium alloy steel and heat-treated to reach Grade 12.9 hardness, providing maximum resistance to stretching and breaking under extreme mining loads.
Precision Threading Technology: Features CNC-machined threads with tight tolerances to ensure a secure, vibration-resistant fit that prevents loosening during heavy-duty excavation.
100% OEM Interchangeability: Precision-engineered to match the exact dimensions and material properties of part number 21N-32-31212 for the PC1100 and PC1250 series.
Superior Fatigue Resistance: Undergoes advanced quenching and tempering processes to enhance structural integrity, ensuring long-term durability in high-vibration environments.
Anti-Corrosive Surface Treatment: Finished with a professional black oxide or zinc-plated coating to prevent rust and corrosion, even when exposed to harsh outdoor elements.
Engineered for Mining Conditions: Specifically designed to handle the massive torque and structural stress experienced by Komatsu’s largest mining excavators.
Strict Dimensional Inspection: Every batch is 100% checked for thread accuracy, head geometry, and overall length to ensure zero-defect installation on the jobsite.
Cost-Effective Wholesale Solution: Directly sourced from the Jining industrial hub, offering international distributors significant savings without compromising on technical quality.
Reduced Equipment Downtime: Reliable high-strength fasteners prevent unexpected structural failures, keeping your mining fleet operational and productive.
Micron-Level Filtration Precision: Utilizes high-quality imported synthetic fiber media to capture ultra-fine particles, protecting sensitive hydraulic valves and pumps from premature wear.
100% OEM Compatibility: Precision-engineered to meet or exceed the original 154-49-71990 specifications, ensuring a perfect “drop-in” fit for Komatsu D85PX bulldozers.
High-Pressure Structural Integrity: Features a reinforced internal core and heavy-duty end caps designed to withstand high-pressure spikes and oil surges without collapsing.
Optimized Oil Flow Rate: Designed with an advanced pleated structure to maximize the filtration surface area while maintaining a low pressure drop for consistent machine power.
Premium Temperature-Resistant Seals: Equipped with high-grade Viton or Nitrile rubber O-rings that maintain their sealing integrity in extreme heat and high-vibration environments.
Superior Contaminant Holding Capacity: The multi-layer media design allows for longer service intervals, reducing overall maintenance costs and machine downtime.
Rigorous Quality Control: Each element undergoes strict bypass valve and bubble point tests to ensure zero leakage and consistent performance across every batch. Corrosion-
Resistant Components: All metal parts are treated with a specialized coating to prevent rust and oxidation during storage or operation in humid conditions.
Direct Jining Hub Sourcing: Located in the global center of Komatsu parts production, providing international wholesalers with factory-direct pricing and rapid dispatch.
