SH220/260/280 HRC53-57 Excavator Front Idler For Undercarriage Elements NO-KRA0856/KRA1198

 High Quality      

  The product boasts a wheel body distinguished by its innovative box-shaped design, meticulously crafted through casting processes that employ either alkaline phenol-formaldehyde resin sand or sodium silicate sand as the foundational 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, with a hardening depth of at least 4-6mm (reaching HRC45 at this depth). This robust construction ensures exceptional resistance to high impacts and wear, even under the most demanding operational conditions.

High Precision

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

High Durability

  The guide wheel showcases a unique integrated design, paired with precise heat treatment specifications, resulting in superior strength, impact resistance, and a notably hard tread surface with substantial hardening layer depth. 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, guaranteeing smooth and consistent operation of the entire system.
