Komatsu PC300 Excavator Track Pin Supplier

Among the key parts of the excavator, the pin assembly plays an important role in connecting the upper and lower parts and supporting the articulation. For medium and large excavators such as the PC300 model, the excavator track pin and T-shaped master pin excavator must not only withstand huge impacts and frequent motion loads, but also maintain precise connection and high-strength support during long-term work. As a professional excavator parts manufacturer, GFM provides track pins and T-shaped master pin excavator designed and adapted for PC300, which fully meet the high standards of strength, precision and durability.

Track pin and T-shaped excavator track master pins suitable for PC300 are usually used in key connection parts such as buckets, bucket pins, etc. The following are the core features of the product:

High-strength alloy steel material
We use heat-treated 40CR high-strength materials to ensure that the product will not bend or deform under high load conditions. Through tempering and induction quenching, the surface hardness can reach HRC 48-52, which effectively improves wear resistance and extends service life.

Precision dimensional processing
The product accuracy is controlled within ±0.01mm, strictly following the original factory matching standard dimensions of PC300. Especially the T-shaped live pin, its design structure is convenient for quick installation and disassembly, avoiding the early wear problem caused by positioning deviation of traditional pins.

Surface anti-corrosion treatment
We galvanize, electrophoresis or phosphate the surface of the pin to enhance its corrosion resistance, suitable for stable operation under complex working conditions such as rain, mud, dust, etc., not easy to rust or bite.

Factory Advantages

More than 14 years of dedicated experience, creating a reputation for quality
GFM has more than 15 years of experience in the production of excavator parts, focusing on the research and development and manufacturing of bucket shafts, bucket pins, bushings, chains, crawlers and other structural parts. We are well aware of the importance of each component to the performance of the whole machine, so each pin is subject to strict quality control processes from material selection to delivery.

CNC precision processing equipment and multiple inspection processes
In the GFM factory, we use high-precision CNC lathes, automatic grinders, and drilling equipment for mass production to ensure the stability and interchangeability of each batch of products. All products must pass four procedures before leaving the factory, including hardness testing, dimension inspection, appearance inspection and static load test, to ensure 100% qualification.

Customized service support makes equipment adaptation more flexible
We understand that different working conditions have different requirements for pin size, structure and material processing. GFM provides OEM and ODM customization services, supports customization according to drawings, and can also recommend more suitable materials and heat treatment solutions according to the use environment provided by customers. For example:

• Customized diameter/length: supports non-standard customization at the 5mm level;
• Special material selection: such as 38CrMoAl, 20MnTiB and other higher-grade alloys;
• High-frequency quenching or nitriding treatment: adapt to high-wear operations;
• Add retaining rings, lubrication holes or threaded interfaces: improve assembly convenience and maintenance performance.

PC300 excavators need high reliability and high efficiency at the work site, but a seemingly small pin may affect the operation of the entire machine. GFM always insists on using good materials, fine processing, and sufficient process control, just to reduce equipment downtime and make customers feel more at ease.
