Komatsu PC300-6 Excavator Track Sprocket

Komatsu PC300-6 excavators are very popular in heavy engineering operations, and the drive sprocket, as one of the key transmission components, directly affects the traction performance and service life of the whole machine. If you are looking for a high-quality, reliable, durable and customizable Komatsu PC300-6 excavator track sprocket, then GFM will be your trusted partner.

Why is the Komatsu PC300-6 excavator track sprocket so important?

The drive sprocket, also called the drive gear, is located at the tail of the excavator and is one of the core components of the crawler drive system. It transmits the power generated by the engine to the crawler by precisely engaging with the track pitch, realizing the forward and steering of the whole vehicle. For medium and large excavators such as PC300-6, the drive sprocket must withstand high loads, high-frequency impact and wear, so its wear resistance, strength and processing accuracy are very critical.

Poor quality sprockets may cause:

• Transmission jamming or excessive noise
• Track derailment or abnormal wear
• Reduced excavator efficiency
• Frequent replacement leads to high maintenance costs

Choosing excavator sprockets produced by GFM will effectively avoid the above problems and make your equipment run more smoothly and efficiently.

Production Process

Raw material selection and chemical composition control

• We strictly select high-quality alloy steel from well-known steel mills at home and abroad, and the chemical composition is tested by a spectrometer to ensure that the content of elements such as C, Cr, and Mo is accurate and stable.

High-temperature forging and preliminary shaping

• Forging at a high temperature of more than 1,200 ℃ makes the internal grains refined and the structure dense. After preliminary shaping, it is put into storage for inspection.

Multi-stage heat treatment strengthening

• Normalizing: 850–900 ℃ uniform heating to refine the metal structure.
• Quenching: Rapid cooling under oil cooling medium, the hardness is increased to HRC 48–52.
• Double tempering: 580–620 ℃ for more than 2 hours to eliminate internal stress and improve toughness.

CNC precision machining and online measurement

• Imported five-axis linkage CNC machine tools are used, and the machining tolerance is controlled at ±0.02 mm. Critical dimensions are tested online using a three-coordinate measuring machine to ensure that every piece leaves the factory with precision.

Factory Advantages

GFM excavator sprocket suppliers has more than 20 years of experience in manufacturing excavator undercarriage parts. It has a modern factory equipped with large CNC lathes, plasma cutting machines, high-frequency heat treatment furnaces, sandblasting lines and other professional equipment. Each drive sprocket is produced and sold by GFM itself, without relying on outsourcing, with more controllable quality and more stable delivery time.

From blank forging, rough machining, fine machining, heat treatment, surface treatment to inspection and packaging, we have built a complete production closed loop to ensure that each process has a dedicated person in charge and each dimension is traceable.

GFM’s drive sprockets designed for Komatsu PC300-6 excavators are produced strictly in accordance with the original factory standards (OEM specifications). The parameters such as pitch, tooth shape, and screw hole distribution correspond to the original accessories one by one, ensuring a smooth assembly process and stable operation without chain jams. We use CNC machining centers for gear cutting and precision control to ensure that the hardness and precision of the tooth surface are within the error range of ±0.01mm.

High-strength material, wear-resistant and not easy to crack
Our sprocket base is made of high-strength steel. After quenching and tempering heat treatment, the hardness reaches HRC50-55, and then medium-frequency quenching is used to improve the strength of the tooth surface and the impact resistance is increased by 40%. This means that no matter in harsh working conditions such as high humidity, muddy, and dense sand and gravel, GFM drive sprockets can maintain high efficiency and extend their service life by 30%-50% compared to ordinary products on the market.

Surface treatment, anti-rust and anti-corrosion
Every sprocket is shot peened and coated with anti-rust coating before leaving the factory, which effectively resists external environmental erosion, avoids early rust and tooth surface damage, and is especially suitable for high humidity and hot areas such as Southeast Asia and Africa.
