Premium heat-treated forged steel undercarriage parts designed for maximum durability and performance in demanding mining and construction applications.
What is an Idler?
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 service life with all undercarriage components—effectively eliminating uneven wear.
Manufactured through premium alkali phenolic resin sand casting or sodium silicate-bonded sand casting processes, this idler delivers robust construction and perfect dimensional stability. After specialized heat treatment, it achieves HRC 48-58 surface hardness with 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 ensures precise dimensional accuracy and smooth surface finish for seamless assembly. The extended service life reduces frequent part replacements, minimizing maintenance-related safety hazards and contributing to workplace safety improvements.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
Splined idler-shaft connection: Aligns service life with other undercarriage components, preventing uneven wear and enhancing long-term reliability
Heavy-duty rock guard: Protects against dirt, rubble and debris in demanding mining and construction environments
Dedicated lubrication injectors: Provide precise lubrication to high-wear areas, preventing friction-induced failures
Expanded bearing surface + optimized oil flow: Enhances track stability and operational responsiveness on rough terrain
Cost-Smart Engineering: Lower Total Cost of Ownership
Prolonged track life: Reduces operational costs by minimizing downtime and part replacement frequency
50% less bearing stress: Significantly reduces bearing failures, lowering parts and repair expenses
