1. What is a Idler?

The CHT idler combines advanced design with precision manufacturing to deliver exceptional durability and safety. Its keyed joint between the idler and axle enlarges the bearing contact area and enhances torque transmission—a design that not only boosts reliability, but also synchronizes the idler’s service life with other undercarriage components to prevent uneven wear. Additionally, the axle’s smooth rotation inside fixed bearings drastically reduces friction and wear, thereby further prolonging the track system’s overall service life.

Manufactured using either alkali phenolic resin sand casting or sodium silicate-bonded sand casting (two processes selected specifically for crafting robust, dimensionally stable components), the CHT idler undergoes specialized heat treatment. This process yields a minimum surface hardness of HRC 48–58 and a 4–6mm hardened layer (with the layer maintaining HRC 45), equipping it with outstanding impact resistance and wear resistance—even in the harshest mining or construction environments.

Final precision machining is performed on a large-scale CK5110 CNC vertical lathe, ensuring impeccable dimensional accuracy and excellent surface finish. This rigorous refinement guarantees consistent operational stability and a reliably long service life for the idler. In real-world applications, the extended lifespan of the track system reduces replacement cycles, directly minimizing workers’ exposure to safety hazards during maintenance—underscoring that long-lasting performance and workplace safety are inherently interconnected.

2. Idler Characteristic

2.1 Tech-Driven Durability: Built to Outlast

50% reduced bearing pressure: Drastically reduces bearing load, extending component life by 2x or more and doing away with the hassle of frequent replacements.
Splined idler-shaft connection: Locks in unrivaled reliability while aligning the idler’s lifespan with other critical undercarriage parts—avoiding uneven wear that shortens overall system life.
Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble, and debris, shielding vulnerable components from damage that would lead to costly repairs or replacements.

2.2 Efficiency-Focused Design: Minimize Downtime, Maximize Output

Detachable bearing blocks with bushings: Enable removal and servicing without disassembling the track, trimming maintenance time by up to 40% and getting equipment back online quicker.
Dedicated lubrication injectors: Supply precise lubrication to high-wear surfaces, preventing friction-related failures and cutting down on unplanned downtime.
Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness, even in rough mining conditions where consistent performance is critical.

2.3 Cost-Smart Engineering: Lower TCO, Higher Returns

Rotating shaft + stationary bushings: Reduces contact stress and wear, slashing unplanned stoppages that eat into profits and disrupt daily operations.
Prolonged track system life: Lowers total mining operational costs by reducing downtime and the frequency of part replacements.
50% less bearing stress: Directly results in fewer bearing failures, reducing both parts costs and repair-related labor expenses.
