Hitachi Construction Machinery EX60 Bulldozer 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. 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—preventing uneven wear and optimizing power transfer efficiency.
Manufactured through either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, the idler undergoes specialized heat treatment achieving a surface hardness of HRC 48-58 with a 4-6mm hardened layer (maintaining HRC 45), providing superior impact and wear resistance in harsh mining or construction environments.
Final precision finishing on a CK5110 large-scale CNC vertical lathe ensures dimensional accuracy and smooth surface finish, guaranteeing precise fit during assembly while reducing maintenance frequency and improving workplace safety.
- 50% reduced bearing pressure: Extends component life by 2x or more, eliminating frequent replacements.
- Splined idler-shaft connection: Ensures reliability while aligning the idler's lifespan with other undercarriage parts.
- Heavy-duty rock guard: Protects against dirt and debris, preventing damage and costly repairs.
- Detachable bearing blocks with bushings: Reduces maintenance time by up to 40% without track disassembly.
- Dedicated lubrication injectors: Provides precise lubrication to high-wear surfaces, preventing friction-related failures.
- Expanded bearing surface + optimized oil flow: Enhances track stability and responsiveness in rough conditions.
- Rotating shaft + stationary bushings: Reduces contact stress and wear, minimizing unplanned stoppages.
- Prolonged track system life: Lowers operational costs by reducing downtime and part replacements.
- 50% less bearing stress: Fewer bearing failures reduce parts and labor costs.
