PC1250 Forge Steel Front Idler Group - Komatsu Bulldozer Durable Heat Treatment Undercarriage Spare Parts 21N-30-00140

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.
