Reliable Undercarriage Parts Manufacturing Process

YASSIAN controls the complete manufacturing process of undercarriage spare parts, from raw material selection to final inspection.

Our production process includes precision machining, welding, heat treatment, surface hardening, assembly, and quality testing to ensure every component meets strict performance requirements.

Track rollers, idlers, and track links are carefully inspected for dimensional accuracy, hardness, sealing performance, and structural reliability before shipment.
  • Track Roller: Machining → Welding → Inspection → Assembly → Sealing Test → Final Inspection

    Track Roller2

    TRACK ROLLER (FORGE) PRODUCTION

    1. MACHINING: Machining the size according to the drawing and testing the main dimensions

    2. WELDING: Track surface induction and tempering. CO2 Gas protection welding and measure the outer diameter. Grinding after welding. Test hardness during the process.

    3. INSPECTION: After welding,machine the inner hole and inner length of the entire precision wheel body to ensure the concentricity and flatness of the wheel body. It can be removed only after passing the measurement on the machine.

    4. ASSEMBLING: Assembling and checking the dimensions.

    5. INSPECTION: Dip into water after injecting the gas to test the sealing performance; Vacuum oil injection; Rolling test.

     

    FINISHING TOUCHES AND STORAGE:

    After all the above processes are completed, the track rollers (forge) will undergo a final inspection for any surface defects or irregularities. Any necessary touch-ups, such as polishing or painting, will be carried out at this stage. Subsequently, the finished track rollers will be carefully stored in the warehouse, ensuring they are protected from dust, moisture, and other potential damage until they are ready for shipment.

  • Track Links: Heat treatment → Machining → Surface induction → Hardness testing → Assembly inspection

    TRACK LINKS PRODUCTION (RAW MATERIAL)

    1. RAW MATERIAL: Heating the material to 950℃-1100℃; Forging as the mould shape

    2. CUTTING: Cooling after cutting, keep the hardness

    3. HEATTREATMENT: The residual heat oil is quenched and then subjected to high temperature; No uncleaned oxide scale,cracks or obvious pits on the surface.

    4. MACHINING: Drilling the holes and making the hole dimensions and distance; making the hole dimensions, link height.

    5. SURFACE INDUCTION: Outer surface Induction and tempering. The rail surface is subjected to high-frequency quenching, followed by rapid cooling after heating and low-temperature tempering.

    6. HARDNESS TEST: Before tempering HRC:63.5; after tempering HRC:55.5.

    7. ASSEMBLY AND INSPECTION: After all the individual components are machined and heat-treated, they are assembled according to the design specifications. Each assembled track roller undergoes a rigorous inspection process to ensure it meets the required dimensional tolerances, surface finish, and hardness standards. This includes checking for proper fit and alignment of all parts, as well as verifying that there are no defects or irregularities that could affect performance.

    8. PACKAGING AND STORAGE: Once the track rollers pass the inspection, they are carefully packaged to protect them from damage during transportation and storage. The packaging materials are chosen to provide adequate cushioning and support. The packaged track rollers are then stored in a designated warehouse area, where they are organized by size, type, and customer order to facilitate easy retrieval and shipping when needed. The warehouse environment is controlled to maintain optimal temperature and humidity levels, further ensuring the quality and longevity of the track rollers.

  • Track Links Production (Precision Machining)

    Track Links Production1
    Track Links Production2

    1. Precision machining for the hole to make sure the accurate dimension.

    2. PINS MACHINING: Process the total length as required,and roughly turn the outer circle, leaving an allowance for fine grinding.

    3. Pins hardness testing: Hardness:HRC58.0

    4. ASSEMBLY, OILING AND INSPECTION: Inspect the main size after assembling

    5. PAINTING: Painting process: Apply high - quality anti - corrosion paint evenly on the surface of the track roller (forge) to ensure a smooth and uniform coating, which can effectively prevent rust and corrosion during storage and use.

    6.Warehouse management: Store the painted track rollers (forge) in a dry, well - ventilated, and clean warehouse. Arrange them in an orderly manner according to specifications and models, with clear labels for easy identification and retrieval. Regularly check the storage conditions and the status of the products to ensure their quality remains intact.

  • Positive Pin Retention (PPR) Track

    Positive Pin Retention (PPR) Track

    Resists link end play and increases sealability for maximum track life. Designed for high-impact and high-loading applications such as mining, heavy construction.

    Its robust construction ensures that the track rollers maintain stability and performance even under extreme conditions. The unique design minimizes wear and tear, thereby extending the service life of the track system. Additionally, the Positive Pin Retention Track enhances the overall durability of the machinery, reducing maintenance costs and downtime. This makes it an ideal choice for industries that demand reliability and efficiency in their operations.
