D85 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 alloy steel raw material with overall quenching treatment, outstanding wear resistance for heavy-load mining and earthmoving.
2. Precision machined shaft and roller shell with matched clearance, effectively avoiding oil leakage and premature bearing damage.
3. Premium floating oil seal structure blocks mud, silt and sewage, adapting to severe muddy and rocky construction sites.
4. Strictly follows OEM dimensional standard of D85 bulldozer, direct mounting replacement without modification.
5. Optimized outer circle curvature lessens impact friction with track chain, prolonging chassis service cycle and cutting maintenance cost. 6. Full load durability inspection before delivery, stable bearing capacity for long-time continuous heavy-duty operation.
D85 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.
