Durable and Long-Lasting D7G Bulldozer OEM Undercarriage Spare Parts Forge Steel Front Idler Assembly With Heat Treatment

What is an 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, aligning the idler's service life with other undercarriage components while eliminating uneven wear. The axle's rotation within fixed bearings significantly reduces friction and wear, extending the track system's longevity.

Crafted via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, it undergoes specialized heat treatment to achieve a minimum surface hardness of HRC48-58 and a 4-6mm hardened layer (HRC45), providing exceptional impact and wear resistance. Final precision refinement on a CK5110 large-scale CNC vertical lathe ensures impeccable dimensional accuracy and superior surface finishes.

Idler Characteristics

Tech-Driven Durability: Built to Outlast

50% reduced bearing pressure: Drastically reduces bearing load, extending component life by 2x or more.
Splined idler-shaft connection: Locks in 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.

Efficiency-Focused Design: Minimize Downtime, Maximize Output

Detachable bearing blocks with bushings: Enable removal and servicing without disassembling the track, reducing maintenance time by up to 40%.
Dedicated lubrication injectors: Supply precise lubrication to high-wear surfaces, preventing friction-related failures.
Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness in rough conditions.

Cost-Smart Engineering: Lower TCO, Higher Returns

Rotating shaft + stationary bushings: Reduces contact stress and wear, slashing unplanned stoppages.
Prolonged track system life: Lowers operational costs by reducing downtime and part replacements.
50% less bearing stress: Results in fewer bearing failures, reducing parts and labor costs.
