Product Specification

Heavy-Duty Forged Steel Front Idler Group for CAT E320 Excavator - Construction Machinery Undercarriage Spare Parts 113-2907

1. What is a Idler?

    1.1 The CHT idler boasts exceptional durability and safety, backed by advanced design and precision manufacturing. Its keyed joint between idler and axle widens the bearing contact area, enhances torque transmission, and aligns the idler’s lifespan with other undercarriage components—avoiding uneven wear—while the axle’s rotation inside fixed bearings reduces friction, further extending the track system’s service life.

    1.2 It’s manufactured via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting—processes ideal for crafting heavy-duty parts that are robust and dimensionally stable. After specialized heat treatment, it achieves HRC 48–58 surface hardness and a 4–6mm hardened layer (HRC 45), equipping it with strong impact and wear resistance for harsh mining or construction sites.

2. Idler Characteristic

2.1 Tech-Driven Durability: Built to Outlast

• Splined idler-shaft connection: Aligns the idler’s service life with other key undercarriage parts, preventing uneven wear that shortens the entire system’s lifespan and enhancing long-term reliability.

• Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble and debris, shielding vulnerable components from damage in dusty, gravelly mining/construction sites to avoid costly repairs and premature breakdowns.

2.2 Efficiency-Focused Design: Minimize Downtime

• Dedicated lubrication injectors: Deliver precise lubrication to high-wear areas, preventing friction-induced failures that trigger unexpected downtime and keeping daily operations consistent and on schedule.

• Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness, ensuring steady performance even in rough, uneven mining sites—where consistent operation is critical to meeting output goals.

2.3 Cost-Smart Engineering: Lower TCO

• Prolonged track life: Lowers total operational costs by reducing downtime losses and part replacement frequency, delivering long-term savings for mining operations.

• 50% less bearing stress: Directly translates to fewer bearing failures, slashing both parts procurement and repair labor costs to lower overall total cost of ownership.
