No. 200102-00022 Doosan Front Idler Group for DX225
Premium excavator undercarriage spare parts manufactured with advanced heat-treatment technology for exceptional durability and performance.
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, boosts torque transmission efficiency, and synchronizes the idler's service life with all undercarriage components, effectively eliminating uneven wear.
Manufactured via 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.
Splined idler-shaft connection aligns service life with other undercarriage parts, preventing uneven wear
Heavy-duty rock guard protects against dirt, rubble and debris in demanding environments
Cost-Smart Engineering: Lower Total Cost of Ownership
Rotating shaft with stationary bushings reduces contact friction and wear significantly
Prolonged track life lowers total operational costs by reducing downtime and replacement frequency
50% less bearing stress translates to fewer bearing failures, reducing parts and labor costs
Enhanced Safety
Longer crawler system life increases change-out intervals, reducing employee exposure to safety risks during maintenance and component replacement.
