What is an Idler?

The CHT idler blends advanced design and precision manufacturing to deliver exceptional durability and safety. Its keyed joint between idler and axle expands the bearing contact area, enhances torque transmission, and synchronizes the idler's service life with other undercarriage components—effectively avoiding uneven wear and optimizing power transfer efficiency. Meanwhile, the axle's rotation within fixed bearings significantly reduces friction and wear, further prolonging the overall lifespan of the track system.

Crafted via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting (two processes ideal for producing robust, dimensionally stable parts that suit heavy-duty working conditions), it undergoes specialized heat treatment. This treatment achieves a surface hardness of HRC 48-58 and a 4-6mm hardened layer (maintaining HRC 45), endowing the idler with strong impact resistance and wear resistance—even in harsh mining or construction environments where high friction and heavy impacts are common.

Final precision finishing on a CK5110 large-scale CNC vertical lathe ensures impeccable dimensional accuracy and smooth surface finish, guaranteeing precise fit during assembly. The extended lifespan of the track system reduces replacement cycles, lowering workers' exposure to safety risks from frequent maintenance—effectively linking the idler's long-lasting performance to improved workplace safety.

Idler Characteristics

Tech-Driven Durability: Built to Outlast

50% lower bearing pressure: Slashes bearing load, doubling component lifespan and cutting unplanned downtime from frequent part swaps.
Splined idler-shaft connection: Aligns the idler's life with other undercarriage parts, stopping uneven wear that shortens system life and boosting reliability.
Heavy-duty rock guard: Shields vulnerable parts from dirt/debris in dusty/gravelly sites, avoiding costly repairs and premature failures.

Efficiency-Focused Design: Minimize Downtime

Detachable bushed bearing blocks: Enable fast servicing (no track disassembly), slashing 40% of maintenance time to get gear online quicker.
Dedicated lubrication injectors: Prevent friction failures and unexpected downtime, keeping daily operations steady.
Expanded bearing surface + optimized oil flow: Boosts track stability in rough mining—critical for consistent output.

Cost-Smart Engineering: Lower TCO

Rotating shaft + stationary bushings: Reduces friction/wear, cutting profit-draining unplanned stoppages and hidden costs.
Prolonged track life: Lowers total ops costs via less downtime and part replacements, delivering long-term savings.
50% less bearing stress: Means fewer bearing failures, slashing parts and repair labor expenses.
