SK042/200/230/350 HRC53-57 40Mn Excavator Front Idler For Undercarriage Elements

High Quality      

  The product showcases a wheel body that distinguishes itself with its unique box-shaped design, meticulously formed through casting processes utilizing either alkaline phenol-formaldehyde resin sand or sodium silicate sand as foundational materials. These materials undergo normalization, while the rail surface undergoes medium-frequency induction hardening to achieve a surface hardness ranging from HRC48 to HRC58, with a hardening depth of at least 4-6mm (reaching HRC45 at this depth). This ensures robust resistance to high impacts and wear, even under the most arduous operational conditions.

High Precision

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

High Durability

  The guide wheel features a distinctive integrated design, coupled with precise heat treatment specifications, resulting in high strength, superior impact resistance, and a notably hard tread surface with substantial hardening layer depth. This prolongs the lifespan of the guide wheel, ensuring reliable track support. Furthermore, the incorporation of high-quality sealing components further enhances the reliability of the sealing performance, ensuring smooth and consistent operation of the entire system.
