คําอธิบายสินค้า
K1018457 Doosan Excavator Front Idler Group
Precision heat-treated undercarriage spare parts for Doosan DX140 excavators, engineered for exceptional durability and performance in demanding construction environments.
What is an Idler?
Our idlers are manufactured using advanced casting processes with alkali phenolic resin sand or sodium silicate-bonded sand. Through precision heat treatment, surface hardness reaches HRC48-58 with hardness depth of 4-6mm (HRC45), ensuring exceptional impact resistance and wear performance in harsh working conditions.
Manufactured using CK5110 large-scale precision CNC vertical lathes, our idlers deliver precise dimensions and superior surface finishing. The splined connection between idler and shaft provides enhanced bearing area and optimal torque transfer, increasing reliability and matching service life with other undercarriage components.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
  • 50% lower bearing pressure reduces bearing load and doubles component lifespan
  • Splined idler-shaft connection aligns service life with other undercarriage components
  • Heavy-duty rock guard protects against dirt, rubble and debris in demanding environments
Increased Productivity
  • Splined connection enhances reliability and component life matching
  • Bearing blocks with bushings removable without breaking the track
  • Dedicated lube injectors supply lubricant to critical wear surfaces
Lower Total Cost of Ownership
  • 50% less bearing stress reduces loads and increases component life
  • Rotating shaft within stationary bushings minimizes contact stress and wear
  • Heavy-duty rock guard prevents damage from dirt and debris
Enhanced Safety
Extended crawler system life increases change-out intervals, reducing employee exposure to safety risks during maintenance and component replacement.
