Hitachi EX50 Front Idler Assembly
OEM quality excavator machinery durable heat treatment undercarriage spare parts for sale.
What is an Idler?
The CHT idler features exceptional durability and safety through advanced design and precision manufacturing. Its keyed joint between idler and axle widens the bearing contact area, enhances torque transmission, and aligns the idler's lifespan with other undercarriage components—preventing uneven wear. The axle's rotation inside fixed bearings reduces friction, extending the track system's service life.
Manufactured via either alkali phenolic resin sand casting or sodium silicate-bonded sand casting, these processes create robust, dimensionally stable heavy-duty parts. After specialized heat treatment, it achieves HRC 48-58 surface hardness with a 4-6mm hardened layer (HRC 45), providing strong impact and wear resistance for harsh mining or construction environments.
Final finishing on a CK5110 large-scale CNC vertical lathe ensures precise dimensional accuracy and smooth surface finish for seamless assembly. The extended track life reduces replacement frequency, minimizing workers' exposure to safety hazards during maintenance.
