Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The Kobelco SK17 track roller is an essential undercarriage component designed to support the weight of your mini excavator while ensuring smooth and consistent track movement. A well-functioning track roller not only guarantees stability on uneven terrain but also reduces premature wear on other undercarriage parts, extending the overall lifespan of your machine.
This track roller is engineered specifically for Kobelco SK17 excavators, meeting or exceeding OEM standards for performance and durability. It is ideal for operators working in construction, landscaping, agriculture, and other industries where compact excavators are used.
Manufacturing Process of SK17 Track Rollers
To withstand demanding work conditions, this SK17 track roller is manufactured using high-strength alloy steel. Each roller undergoes:
Heat Treatment
The track roller undergoes a controlled heat treatment process to enhance the hardness and toughness of the steel. This step ensures that the roller surface achieves the ideal balance between wear resistance and impact strength. With precise temperature control and quenching methods, the roller achieves a hardness of HRC 52–58, allowing it to withstand harsh working conditions such as rocky terrain and heavy excavation tasks.
Machining Process
After heat treatment, the roller body enters the precision machining stage. Using CNC lathes and grinding equipment, each roller is processed to meet exact dimensional tolerances. This guarantees a perfect fit with the shaft and sealing components. Machining also ensures smooth surface finishes, which reduce friction during operation and contribute to longer service life.
Assembly
During assembly, the roller shell, shaft, bushings, and seals are carefully fitted together. The use of high-quality seals prevents oil leakage and protects the roller from dust, mud, and water intrusion. Strict assembly procedures ensure that each component works harmoniously, resulting in a roller that operates smoothly and consistently in tough working environments.
Running Test
Before leaving the production line, each track roller undergoes a dynamic running test. This test simulates real working conditions by rotating the roller under load, checking for abnormal noise, resistance, or vibration. It ensures the roller is well-lubricated, properly sealed, and capable of delivering reliable performance once installed on the excavator.
Paint Spraying
Once the mechanical testing is complete, the roller is coated with anti-rust primer and durable paint. This not only gives the roller a clean and professional finish but also protects it against corrosion and harsh weather exposure. The paint coating extends the service life of the roller, especially in humid or muddy working environments.
Packing
The final step is secure packing to ensure safe transportation. Rollers are individually wrapped or palletized in wooden crates, with protective layers to prevent scratches or rust during long-distance shipping. Each package is clearly labeled with product information, making it easier for customers to identify and install the correct part.
