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 track roller, also known as the bottom roller, is one of the most essential components in the undercarriage of the Yuchai YC13 excavator. It directly supports the machine’s weight, guides the track chain, and helps distribute the load evenly across the ground. A high-quality roller not only improves stability and maneuverability but also reduces vibration and wear on the track system, extending the overall service life of the undercarriage.
Material and Heat Treatment
Our YC13 track rollers are manufactured using high-grade alloy steel, carefully selected for strength and toughness. Each roller undergoes precision heat treatment—including quenching and tempering—to achieve a surface hardness of HRC 52–58. This process strengthens the outer surface against abrasion while preserving a resilient core to withstand heavy shock loads. The result is a roller that performs reliably even in abrasive soils, rocky terrains, and construction environments with constant impact.
Manufacturing Process
The Yuchai YC13 track roller is produced under a strict manufacturing workflow to guarantee durability and performance:
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.
Excavator YC85 Bottom Roller : Function and Performance
The YC85 track roller is a vital component of the undercarriage system, providing essential support for the machine’s track chain. It ensures consistent contact with the ground, balances the load weight of the excavator, and stabilizes track movement during travel and excavation. Especially designed for mid-sized Yuchai machines, this roller enables smooth operations on construction sites, agriculture, and light demolition jobs.
High-Strength Materials for Extended Service Life
Material Composition and Wear Resistance
Each YC85 bottom roller is manufactured with premium-grade forged 45# steel or equivalent alloy. The surface is induction hardened to achieve HRC 52–58, significantly enhancing wear resistance and impact strength. The internal bushing is made from high-performance alloy such as 40Cr or 42CrMo, ensuring long-term performance even under continuous load and motion.
Optimized Heat Treatment and Precision Machining
Through precision CNC machining and multi-stage heat treatment, the YC85 roller achieves perfect dimensional tolerances and superior structural integrity. The heat treatment process enhances both the roller’s core toughness and surface hardness, making it resilient in abrasive and muddy conditions often encountered on job sites.
Manufacturing Process for YC85 Bottom Roller
Our production workflow includes forging, rough machining, heat treatment, finish machining, seal installation, and final inspection. We utilize automated machining centers to guarantee consistency, and each unit is assembled with high-quality floating seals to maintain oil retention and internal lubrication. This ensures stable performance with minimal maintenance.
