Product Description
DH55/258/300 Excavator Front Idler For Construction parts
The idler is vital for ensuring the smooth operation of the track links and preventing their displacement. It also supports a portion of the weight, strengthening the track links and reducing the ground pressure they generate. A central arm supports the track link, enabling its movement in both directions. A small gap between the idler and the track roller enhances alignment and directional stability, ensuring efficient and precise performance.
High Quality
The product showcases a wheel body characterized by a distinctive box-shaped design, meticulously crafted through casting processes that utilize either alkaline phenol-formaldehyde resin sand or sodium silicate sand as the base material. This material undergoes normalization, while the rail surface undergoes medium-frequency induction hardening to attain a surface hardness ranging from HRC48 to HRC58, accompanied by a hardening depth of at least 4-6mm (reaching HRC45 at this depth). This ensures that the product can withstand high impacts and wear, even under harsh operational conditions.
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 ensures 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 features a unique integral design, combined with precise heat treatment specifications, which provide high strength, impact resistance, and an exceptionally hard tread surface with substantial depth in the hardening layer. This contributes to an extended service life for the guide wheel, ensuring reliable support for the track. Additionally, the incorporation of high-quality sealing components further bolsters the reliability of the sealing performance, guaranteeing smooth and stable operation of the entire system.
