코마츠 PC200-5 47L chain

For heavy-duty construction machinery, the stability of the undercarriage travel system is crucial to ensuring operational efficiency. We offer high-quality, highly wear-resistant undercarriage track chains for the Komatsu PC200-5 excavator. This model comes standard with 47 links (47L) and utilizes an optimized heat treatment process to deliver superior tensile strength and wear resistance. **Technical Specifications and Key Advantages** **Compatible Models:** Komatsu PC200-5 / PC200-6 series (please verify your specific pitch and width requirements) **Specifications:** 47 links (47L) **Structural Features:** * **High-Frequency Quenching:** The track link surfaces undergo deep high-frequency quenching, resulting in exceptional surface hardness capable of withstanding continuous abrasion from sand, gravel, and hard terrain on the pins and link surfaces. * **Reinforced Pins and Bushings:** Manufactured from special alloy steel and featuring a high-performance sealing structure, these components effectively block mud and grit from entering the pin bores. This eliminates issues such as "chain elongation" and abnormal pin wear that can cause the track to loosen or detach. * **Precision Forging:** The track links are precision-forged as single units, ensuring a dense internal material structure and high impact resistance, effectively preventing breakage during heavy-load slewing operations. * **Compatibility:** Designed in strict accordance with OEM dimensional specifications to ensure perfect meshing with drive sprockets, track rollers, and idlers, resulting in minimal travel resistance and low energy consumption. **About Us** Guangzhou Jianming Machinery Equipment Co., Ltd. is an expert in the field of mechanical power systems and components, backed by 20 years of solid practical experience.
