Product Description
SK07N2 Bulldozer Front Idler For Bulldozer Construction parts
1. What Is front idler ?
The Idler holds significant importance in guaranteeing smooth functionality of track connections and avoiding deviation. It also distributes some weight, enhancing structural integrity and decreasing surface pressure caused by these units. Placed in the middle, a brace supports every track piece, allowing movement management in both ways. A small clearance between the Idler and the wheel promotes system-wide alignment and consistent direction, ensuring reliable and exact performance.

2. Advantages / Features
High Quality
Normalization is applied to this material to enhance its qualities, and the rail's surface is processed through medium-frequency induction hardening, achieving a hardness level of HRC48 to HRC58, with a hardened region depth of at least 4-6mm (attaining HRC45 at this designated depth).
High Precision
Fabricated with a cutting-edge CK5110 large-scale CNC vertical lathe, the component adheres to exacting standards for internal and external measurements and surface polish. This ensures consistent performance of the final guide wheel, boosting the endurance of the mounted parts and guaranteeing system steadiness.
High Durability
Featuring an innovative layout, the guide wheel is subjected to exact heat treatment for increased toughness, resists collisions, and has a durable tread with a deeply treated area, enhancing longevity and ensuring track integrity. Premium sealing materials strengthen reliability, providing smooth and stable operation.
