Forged Steel Undercarriage Spare Parts for D31 Heavy Duty Idler Assembly for Bulldozer

The CHT idler is engineered for uncompromising durability and workplace safety, featuring advanced structural design and precision manufacturing. Its keyed idler-axle joint widens the bearing contact area, enhances torque transmission efficiency, and synchronizes the idler's service life with all undercarriage components, effectively eliminating uneven wear. The axle's rotation within fixed bearings minimizes friction, extending the overall track system's lifespan.

Manufactured through premium processes including alkali phenolic resin sand casting or sodium silicate-bonded sand casting, this idler features robust construction and perfect dimensional stability. After specialized heat treatment, it achieves HRC 48-58 surface hardness and a 4-6mm hardened layer (HRC 45), providing outstanding impact and wear resistance for harsh mining and construction conditions.

Final finishing on a CK5110 large-scale CNC vertical lathe guarantees precise dimensional accuracy and smooth surface finish for seamless assembly. The extended service life reduces frequent part replacements, minimizing worker exposure to safety hazards during maintenance and linking long-lasting performance to workplace safety improvements.
