Product Description
DH300 Excavator Undercarriage Spare Parts - Precision Forged Steel Front Idler Group
What is an Idler?
The CHT idler delivers exceptional durability and operational safety, engineered with advanced design and precision manufacturing. Its keyed joint between idler and axle expands the bearing contact area, boosts torque transmission, and synchronizes the idler's lifespan with other undercarriage components to eliminate uneven wear. Meanwhile, the axle's rotation inside fixed bearings reduces friction significantly, further extending the entire track system's service life.
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 a 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: Engineered to Outlast Harsh Conditions
- 50% lower bearing pressure: Drastically lowers bearing load, doubling component lifespan at the source. Eliminates the hassle of frequent replacements and slashes unplanned downtime caused by part swaps.
- Splined idler-shaft connection: Synchronizes the idler's service life with all key undercarriage components, preventing uneven wear that shortens the entire system's lifespan and boosting long-term operational reliability.
- Heavy-duty rock guard: Serves as a rugged protective barrier against dirt, rubble and debris, shielding vulnerable internal components from damage in dusty, gravelly mining and construction sites—avoiding costly unplanned repairs and premature equipment breakdowns.
Efficiency-Focused Design: Minimize Downtime, Maximize Uptime
- 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.
Cost-Smart Engineering: Lower Total Cost of Ownership (TCO)
- Rotating shaft + stationary bushings: Reduces contact friction and wear significantly, cutting profit-eroding unplanned production stoppages and the hidden costs associated with operational disruptions.
- Prolonged track life: Lowers total operational costs by reducing downtime losses and the frequency of part replacements, delivering tangible long-term savings for mining and construction operations.
- 50% less bearing stress: Translates directly to far fewer bearing failures, slashing both parts procurement costs and repair labor expenses to drive down your overall total cost of ownership.
