Komatsu Excavator PC400 Machinery OEM Heat Treatment Undercarriage Spare Parts Forge Steel Front Idler Assembly

The CHT idler combines advanced design with precision manufacturing to deliver exceptional durability and safety:

• Keyed joint between idler and axle expands bearing contact area, enhances torque transmission, and synchronizes service life with other undercarriage components
• Manufactured using either alkali phenolic resin sand casting or sodium silicate-bonded sand casting for dimensional stability in heavy-duty conditions
• Specialized heat treatment achieves HRC 48-58 surface hardness with a 4-6mm hardened layer (maintaining HRC 45) for superior impact and wear resistance
• Final precision finishing on CK5110 large-scale CNC vertical lathe ensures perfect dimensional accuracy and smooth surface finish

• 50% lower bearing pressure: Reduces load and doubles component lifespan
• Splined idler-shaft connection: Synchronizes idler life with other undercarriage parts to prevent uneven wear
• Heavy-duty rock guard: Protects against dirt and debris to prevent component damage

• Detachable bushed bearing blocks: Enable servicing without track disassembly, reducing maintenance time by 40%
• Dedicated lubrication injectors: Precisely lubricate high-wear areas to prevent friction failures
• Expanded bearing surface + optimized oil flow: Enhances track stability in rough conditions

• Rotating shaft + stationary bushings: Reduces contact wear and unplanned stoppages
• Prolonged track life: Lowers operational costs by reducing downtime and replacements
• 50% less bearing stress: Fewer failures mean lower parts and labor expenses
