Heavy Duty Precision Heat-treatment Front Idler Group for DX200 (270-00063) - Doosan Excavator Undercarriage Spare Parts
What is an Idler?
The CHT idler is engineered for uncompromising durability and workplace safety, with performance backed by 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. Additionally, the axle's rotation within fixed bearings minimizes friction, further extending the overall track system's lifespan.
Manufactured via alkali phenolic resin sand casting or sodium silicate-bonded sand casting—two premium processes for heavy-duty parts—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), endowing it with outstanding impact and wear resistance to withstand the harshest mining and construction site conditions.
Final finishing is completed on a CK5110 large-scale CNC vertical lathe, which guarantees precise dimensional accuracy and a smooth surface finish for seamless assembly. The idler's extended service life directly cuts down on frequent part replacements, reducing workers' exposure to safety hazards during maintenance and linking the idler's long-lasting performance to tangible workplace safety improvements.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
50% lower bearing pressure: Drastically reduces bearing load, doubling component lifespan from the root. It eliminates frequent replacement hassles and cuts unplanned downtime caused by part swaps.
Splined idler-shaft connection: Aligns the idler's service life with other key undercarriage parts, preventing uneven wear that shortens the entire system's lifespan and enhancing long-term reliability.
Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble and debris, shielding vulnerable components from damage in dusty, gravelly mining/construction sites to avoid costly repairs and premature breakdowns.
Detachable bushed bearing blocks: Enable quick removal and servicing without disassembling the track, cutting maintenance time by 40% to speed up repairs and get your equipment back online faster.
Dedicated lubrication injectors: Deliver precise, targeted lubrication to high-wear areas, preventing friction-induced component failures that trigger unexpected downtime and ensuring consistent daily operations on schedule.
Expanded bearing surface + optimized oil flow: Enhances track stability and operational responsiveness, guaranteeing steady, reliable performance even on rough, uneven mining terrain—where consistent equipment operation is critical to meeting production goals.
Enhanced Safety
Longer crawler system life increases change-out intervals, reducing employee exposure to safety risks from system change-outs and component replacement.
