KOMATSU PC300-3 Slewing Bearing for Excavator
The KOMATSU PC300-3 slewing bearing is a precision slew ring engineered for the swing mechanism of hydraulic excavators, designed to handle combined radial, axial and moment loads in heavy-duty construction and mining environments. This replacement part features alloy steel construction with a case-hardened raceway, ensuring durability under the high-stress conditions typical of KOMATSU PC300-3 excavator operations. It is a direct-fit component, built to restore reliable swing function and minimise equipment downtime on active job sites.
Slew rings for excavators are commonly manufactured to tight tolerances, with typical outer diameters ranging from 400 mm to 1,200 mm for mid-size machines like the PC300-3. The raceway hardening process typically achieves a surface hardness of 55-62 HRC, providing resistance to wear and pitting under cyclic loading. Standard industry practice includes heat treatment to relieve internal stresses, and typical bearing designs incorporate hardened gear teeth for direct drive engagement with the excavator’s swing motor.
These bearings are primarily sourced by earthmoving contractors, equipment rental firms and mining operators maintaining fleets of KOMATSU PC300-3 excavators. Buyers should confirm compatibility with the specific machine serial number, as variations in gear tooth profiles or bolt hole patterns may exist between production batches. The component is typically supplied as a single unit, with packaging designed to prevent deformation during transit, and is intended for professional installation by qualified service technicians.

Sourcing KOMATSU PC300-3 Slewing Bearing for Excavator from Luoyang Justime Co., Ltd. - China Import Guide
Before placing an order, confirm the exact compatibility of the slewing bearing with your KOMATSU PC300-3 excavator by cross-referencing the part number and machine serial number. Verify the supplier’s ability to provide the correct gear tooth profile, bolt hole pattern, and dimensional specifications, as these can vary between production runs. Request a material test report (MTR) to ensure the alloy steel and hardening process meet the required standards for your application.
Discuss logistics details such as lead time, which can vary depending on stock availability and production schedules. Clarify the Incoterms offered (e.g., FOB or CIF) and the port of shipment to calculate total landed costs accurately. Payment terms should also be confirmed, with common options including TT (Telegraphic Transfer) or LC (Letter of Credit) for international transactions. Ensure the supplier can provide a proforma invoice with all terms clearly stated.
Inspect the bearing upon receipt for signs of damage, corrosion, or dimensional inaccuracies. A visual check should be supplemented with measurements of the outer diameter, bolt hole positions, and gear tooth dimensions using calibrated tools. Request a copy of the supplier’s quality control documentation, including hardness test results and surface finish inspections. For critical applications, consider arranging a third-party inspection before shipment to verify compliance with specifications.
