Undercarriage Spare Parts Excavator Idler For Volvo Durable Forge Steel Parts EC55 Front Idler Assembly 

The CHT idler delivers exceptional durability and safety, thanks to advanced design and precision manufacturing. Its keyed joint between idler and axle expands the bearing contact area, enhances torque transmission, and aligns the idler's lifespan with other undercarriage components—preventing uneven wear—while the axle's rotation inside fixed bearings reduces friction, further extending the track system's service life.

It is manufactured via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting—processes perfect for heavy-duty, robust, and dimensionally stable parts. After specialized heat treatment, it reaches HRC 48-58 surface hardness and a 4-6mm hardened layer (HRC 45), giving it strong impact and wear resistance to handle harsh mining or construction conditions.

Final finishing on a CK5110 large-scale CNC vertical lathe ensures precise dimensional accuracy and a smooth surface for seamless assembly. The extended track life cuts down on replacements, lowering workers' exposure to safety risks during maintenance—linking the idler's long service life to better workplace safety.

• 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.

• 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.

• 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.
