HD250 Excavator Front Idler For Vehicle Undercarriage Parts Cast 40Mn

   High Quality   

  The product features a wheel body characterized by its distinctive box-shaped design, meticulously crafted through casting processes using either alkaline phenol-formaldehyde resin sand or sodium silie sand as the base materials. These materials undergo normalization, while the rail surface undergoes medium-frequency induction hardening to attain a surface hardness within the range of HRC48 to HRC58, accompanied by a hardening depth of at least 4-6mm (reaching HRC45 at this depth). This ensures exceptional resilience against high impacts and wear, even in the most demanding operational environments.

High Precision

  Manufactured on a state-of-the-art CK5110 large-scale precision CNC vertical lathe, the product adheres to rigorous standards for both internal and external dimensional accuracy and surface finish. This guarantees a consistent level of quality in the finished guide wheel, thereby enhancing the durability of the installed components and maintaining system stability.

High Durability

  The guide wheel boasts a unique integrated design, combined with precise heat treatment specifiions, resulting in high strength, impact resistance, and an exceptionally hard tread surface with substantial depth in the hardening layer. This extends the lifespan of the guide wheel, ensuring reliable track support. Additionally, the incorporation of high-quality sealing components further bolsters the reliability of the sealing performance, ensuring smooth and consistent operation of the entire system.
