Forged Steel Heavy-Duty Construction Machinery Undercarriage Spare Parts
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 to prevent uneven wear.
Manufactured via alkali phenolic resin sand casting or sodium silicate-bonded sand casting processes, these heavy-duty parts are robust and dimensionally stable. Specialized heat treatment achieves HRC 48-58 surface hardness with a 4-6mm hardened layer (HRC 45), providing strong impact and wear resistance for harsh mining and 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 worker exposure to safety hazards during maintenance.
Heavy-duty rock guard protects against dirt, rubble and debris in demanding environments
Efficiency-Focused Design: Minimize Downtime
Detachable bushed bearing blocks enable quick removal and servicing without disassembling the track
Expanded bearing surface and optimized oil flow boost track stability and responsiveness
Cost-Smart Engineering: Lower Total Cost of Ownership
Rotating shaft with stationary bushings reduces contact friction and wear
50% less bearing stress results in fewer bearing failures and reduced maintenance costs
