Komatsu PC1100 PC1250 Idler for Excavator 21N-30-33110

When you face a high-intensity construction environment, the quality of the idler directly affects the stability and life of the excavator. For super-large excavators such as Komatsu PC1100 and PC1250, the idler is not only a key component for supporting and guiding the track, but also carries huge loads and impact forces. Choosing a truly reliable idler for excavator means less downtime, longer service life and higher construction efficiency.

Highly matched design, specially built for Komatsu PC1100 and PC1250

The idlers we tailor-made for Komatsu PC1100 and PC1250 large excavators are designed with a full set of matching original factory specifications to ensure easy installation, smooth operation and precise fit. Every idler that leaves the factory has undergone strict dimensional inspection and simulated load testing. From hole spacing, bearing structure, seal ring design to the thickness of the external hardness layer, they are equal to or even exceed the original standards.

• Material: We use high-strength alloy steel forgings as raw materials, which have excellent toughness and impact resistance.
• Heat treatment process: multiple quenching and tempering processes are adopted, the wheel surface hardness is high, and the wear resistance is significantly improved.
• Sealing system: standard high-sealing floating oil seal, waterproof and dustproof, to ensure the long-term stability of the internal lubrication of the idler.
• Bearing structure: the inner shaft support adopts a double-row roller bearing structure design to improve the pressure bearing capacity and extend the service life.

We are well aware that in the construction of large-scale equipment, a failure of an idler may cause a shutdown loss of tens of thousands of yuan. Therefore, at the beginning of product design, we started from the perspective of “long-term stable operation”, paid attention to every technical detail, and strived to make the equipment stable and reliable in harsh environments.

Production Process

From design to delivery, every process link of our products is strictly controlled to ensure product stability and durability. The following is an introduction to the basic process flow:

• Material refining
  Select high-strength bearing steel, and improve the purity of the metal through refining, deoxidation and electroslag remelting processes
  The chemical composition of the material is stable and can effectively resist fatigue cracks and impact loads
• CNC machining
  In the rough machining stage, a high-power CNC milling machine is used to quickly shape the blank and strictly control the allowance
  In the fine machining stage, a multi-axis linkage CNC lathe and grinder are used to ensure the dimensional accuracy of the outer circle, inner hole and tooth surface
• Heat treatment strengthening
  The segmented quenching + low-temperature tempering process is adopted, and the hardness is uniform, with high wear resistance and toughness
  Accurately monitor the quenching temperature and holding time to ensure that the internal structure of the parts is stable and crack-free
• Surface treatment
  Shot peening, phosphating, nitriding and other processes can be selected according to customer needs to further improve fatigue resistance
  Under special working conditions, an environmentally friendly high-temperature resistant coating is provided to delay wear and corrosion
• Strict testing and packaging
  Comprehensive use of three-coordinate measuring instruments, roundness meters and hardness testers to ensure that key dimensions and mechanical properties meet the standards
  Dust-proof and moisture-proof packaging, and customized packaging solutions can be provided according to the mode of transportation
