PC200 track roller Products Details
- Wheel body: Made of 40Mn2 round steel with good hardenability through forging; heat treatment process of quenching and tempering + medium-frequency surface quenching ensures its strength and wear resistance.
- Shaft: Made of 45# round steel, with heat treatment process of quenching and tempering + medium-frequency surface quenching, surface hardness HRC52-60, hardened layer depth 3-6mm, with excellent comprehensive performance.
- Floating oil seal: Made of high-chromium and high-molybdenum alloy. Hardness HRC65-72, working surface roughness 0.1uM - 0.2uM.
- O-ring: Made of nitrile rubber raw material produced by copolymerization of butene and acrylonitrile, with better oil resistance and high-temperature resistance.
Key advantages
1.High-Strength Forged Steel Body： Made of 40Mn2 alloy steel, forged + quenched & tempered for superior toughness and load capacity. Withstands heavy impact and shock loads without deformation or cracking.
2.Exceptional Wear Resistance：Surface hardness: HRC 52–60, hardened depth 8–12mm via medium-frequency induction quenching. Resists abrasion from sand, mud and track friction; delivers 2–3× longer service life than standard rollers.
3.Heavy-Duty Sealing System： Equipped with high-chrome/molybdenum floating seals (HRC 65–72) + nitrile rubber O-rings. Blocks dust, water and debris; maintains lubrication in harsh environments (muddy, rocky, wet sites).
4.Precision CNC Machining： Tight dimensional tolerances and perfect fit for PC200-5/6/7/8 undercarriage. Ensures smooth track rotation, reduces vibration and lowers running resistance.
5.Reliable Lubrication & Heat Dissipation： Optimized internal oil cavity design; retains grease longer and dissipates heat effectively. Minimizes friction, prevents overheating and extends bearing life.
6.OEM-Quality Compatibility： Direct replacement for Komatsu PC200 series; interchangeable with part numbers 20Y-30-00012 / 20Y-30-00130. Perfect match with original track groups, idlers and sprockets.
7.Cost-Effective & Low Maintenance：Longer intervals between replacements; fewer breakdowns and less downtime. Reduces total ownership cost for construction, mining and earthmoving projects.
8. Strict Quality Control： 100% heat-treatment inspection + magnetic particle/ultrasonic testing for internal defects. 12-month / 2000-hour warranty guaranteed.
PC200 track roller Applications
Track rollers are core components of excavator undercarriages, essential for the normal operation of excavators in various scenarios.
They are widely used in construction sites, mining areas, road construction, bridge engineering, and agricultural land reclamation.
Whether it is earthmoving, excavation, loading, or leveling, our track rollers provide reliable support for excavators, ensuring efficient and stable operation of the equipment.
They are also suitable for maintenance and replacement of old undercarriage parts, helping customers reduce equipment downtime.
