Komatsu Excavator PC450-8 OEM Heat Treatment Undercarriage Spare Parts Forge Steel Front Idler Group

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.

Crafted via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, it undergoes specialized heat treatment achieving 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.

Final precision finishing on a CK5110 large-scale CNC vertical lathe ensures impeccable dimensional accuracy and smooth surface finish, guaranteeing precise fit during assembly.

• 50% lower bearing pressure: Sharply cuts bearing load, doubling component lifespan.
• Splined idler-shaft connection: Syncs service life with other undercarriage parts.
• Heavy-duty rock guard: Acts as a rugged barrier against dirt and debris.

• Detachable bushed bearing blocks: Enable quick removal and servicing.
• Dedicated lubrication injectors: Precisely deliver lubricant to high-wear surfaces.
• Expanded bearing surface: Enhances track stability and responsiveness.

• Rotating shaft + stationary bushings: Reduces contact friction and wear.
• Prolonged track life: Lowers total operational expenses.
• 50% less bearing stress: Fewer bearing failures and lower repair costs.
