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.

1.3 Final finishing on a CK5110 large-scale CNC vertical lathe guarantees precise dimensional accuracy and smooth surface finish, enabling seamless assembly. The extended track life cuts down on replacements, reducing workers’ exposure to safety hazards during maintenance—tying the idler’s long-lasting performance to enhanced workplace safety.

2. Idler Characteristic

2.1 Tech-Driven Durability: Built to Outlast

• 50% lower bearing pressure: Drastically reduces bearing load, doubling component lifespan from the root. It eliminates frequent replacement hassles and cuts unplanned downtime caused by part swaps.

• 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

• Detachable bushed bearing blocks: Enable quick removal and servicing without disassembling the track, cutting maintenance time by 40% to speed up repairs and get equipment back online faster.

• 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

• Rotating shaft + stationary bushings: Reduces contact friction and wear, cutting profit-eating unplanned stoppages that disrupt production and incur hidden costs.

• 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.
