Product Description

Caterpillar E120 Construction Machinery Bulldozer OEM Undercarriage Spare Parts Heat Treatment Front Idler Assembly

Product Overview

The CHT idler is precision-engineered for endurance and safety in demanding construction and mining environments. Its robust design ensures extended service life while reducing maintenance requirements.

Key Features and Benefits

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.

Efficiency-Focused Design: Minimize Downtime, Maximize Output

Detachable bushing-equipped bearing blocks: Remove and service without disassembling the track--cuts maintenance time by up to 40%.
Dedicated lubrication injectors: Target high-wear surfaces with precise lubricant delivery, preventing friction-related failures.
Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness, even in rough mining conditions.

Cost-Smart Engineering: Lower TCO, Higher Returns

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.

Technical Specifications

Manufactured via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, it undergoes specialized heat treatment post-casting to achieve:

Minimum surface hardness of HRC48-58
4-6mm hardened layer (HRC45)
Exceptional impact resistance and wear resistance
