D155 D355 Construction Machinery Bulldozer OEM Undercarriage Spare Parts Heat Treatment Front Idler Assembly
1. What is a Idler?
At the core of its design, a keyed joint connects the idler to the axle, expanding the bearing surface and enhancing torque transmission. This innovation not only boosts reliability but also aligns the idler’s lifespan with other undercarriage components, eliminating premature wear mismatches. As the axle rotates within fixed bearings, friction and wear are drastically reduced—further extending the durability of the entire track system.
Manufacturing excellence defines the CHT idler: it is crafted using either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, processes chosen for their ability to produce robust, dimensionally stable components. Post-casting, specialized heat treatment yields a minimum surface hardness of HRC48-58 with a 4-6mm hardened layer (HRC45)—attributes that deliver exceptional impact resistance and wear resistance, even in the harshest mining or construction environments.
Precision is finalized on a CK5110 large-scale CNC vertical lathe, ensuring impeccable dimensional accuracy and superior surface finishes. This rigorous, multi-step manufacturing approach guarantees the CHT idler operates with reliable stability and a consistently long service life.
The result? An extended track system lifespan reduces replacement cycles, directly lowering workers’ exposure to safety hazards during maintenance—proving durability and safety go hand in hand.
2. Idler Characteristic
2.1 Tech-Driven Durability: Built to Outlast
50% bearing pressure reduction: Slashes bearing load to extend component life by 2x+—eliminating frequent replacements.
Splined idler-shaft connection: Locks in unbeatable reliability while aligning the idler’s lifespan with other critical undercarriage parts.
Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble, and debris, shielding vulnerable components from costly damage.
Rotating shaft + stationary bushings: Reduces contact stress and wear, slashing unplanned stoppages that eat into profits.
Prolonged track system life: Lowers overall mining operational costs by minimizing downtime and replacement frequency.
50% less bearing stress: Directly translates to fewer bearing failures, reducing both parts costs and labor for repairs.
