Import Excavator Spare Parts — Buy in Bulk from Supplier in China

KSC Construction Machinery Co., Ltd. supplies aftermarket and OEM-equivalent excavator spare parts compatible with Komatsu models, including hydraulic cylinders, bucket teeth, undercarriage components, and swing motors. These parts are manufactured to replicate original dimensions and material properties, with key components such as piston rods made from 42CrMo4 steel and hardened to HRC 50 - 55. Dimensions are based on Komatsu factory blueprints, ensuring direct interchangeability.

The supplier offers both OEM-spec and cost-optimized aftermarket variants. OEM-equivalent parts use similar heat treatment and surface coatings, such as chrome plating on hydraulic rods with thickness of 0.02 to 0.05 mm. Undercarriage rollers and idlers are cast from ductile iron GG-25 with induction-hardened surfaces. These materials are standard in the industry for wear resistance, but the supplier does not specify whether all components undergo the same quality control as Komatsu originals.

Buyers include equipment rental firms, mining contractors, and regional repair centers in Africa, Southeast Asia, and South America. Orders are typically placed in batches of 20 to 200 units, with packaging in cartons or wooden pallets. Trade terms are FOB or CIF, with payment via T/T or L/C. Lead times average 25 to 40 days, depending on part complexity and inventory levels. The supplier does not list certification for individual components beyond general ISO and SGS references.
