D60 friction welding 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. Manufactured via advanced friction welding technology, forming an integrated roller body with superior bonding strength to avoid body separation under heavy load.
2. Seamless welded structure effectively blocks mud, gravel and water infiltration, greatly reducing internal oil leakage and bearing damage.
3. Uniform material stress distribution after welding, enhancing overall impact resistance for rugged mine and construction working conditions.
4. Precision post-weld finishing matches OEM dimension of D60 bulldozer, plug-and-play replacement without any alteration.
5. Consistent surface hardness improves wear lifespan, cutting frequent replacement and later maintenance expenditure. 6. Strict factory load and anti-abrasion tests guarantee stable performance during long-hour heavy-duty bulldozing operations.
D60 friction welding 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.
