1. What is a Idler?

The CHT idler integrates advanced design and precision manufacturing to deliver unmatched durability and safety: its keyed joint between idler and axle expands the bearing surface and enhances torque transmission, a feature that not only boosts reliability but also aligns the idler’s service life with other undercarriage components—eliminating uneven wear—while the axle’s rotation within fixed bearings significantly reduces friction and wear, further extending the track system’s longevity. Crafted via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting (processes chosen for producing robust, dimensionally stable parts), it undergoes specialized heat treatment to achieve a minimum surface hardness of HRC48-58 and a 4-6mm hardened layer (HRC45), endowing it with exceptional impact and wear resistance even in harsh mining or construction settings. Final precision refinement on a CK5110 large-scale CNC vertical lathe ensures impeccable dimensional accuracy and superior surface finishes, guaranteeing consistent stability and a reliably long service life. In practice, this extended track system lifespan cuts down on replacement cycles, directly lowering workers’ exposure to safety risks during maintenance—proving that enduring performance and workplace safety are inherently linked.

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.
