The Hitachi EX750-5 Front Idler Assembly is engineered for superior durability and performance in heavy-duty construction and mining applications. This precision-manufactured component ensures extended service life and reduced maintenance requirements.

The CHT idler combines advanced design with precision manufacturing for exceptional durability and safety. Key features include:

• Idler-axle keyed joint expands bearing surface and enhances torque transmission
• Specialized heat treatment achieves HRC48-58 surface hardness with 4-6mm hardened layer
• Manufactured through alkali phenolic resin sand casting for robust, stable parts
• Final refinement on CK5110 large-scale precision CNC vertical lathe ensures exact dimensions
• Extended track life reduces replacement frequency and maintenance safety risks

50% reduced bearing pressure extends component life by 2x or more. The splined idler-shaft connection ensures reliability while aligning with other undercarriage parts to prevent uneven wear. Heavy-duty rock guard protects against dirt and debris.

Detachable bushed bearing blocks enable 40% faster maintenance without track disassembly. Dedicated lubricators prevent friction failures, while expanded bearing surfaces boost track stability in rough conditions.

Reduces unplanned stoppages and extends track system service life, significantly lowering overall operational costs through decreased downtime and part replacements.
