E70B 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.Excellent wear resistance and long service life: Adopted high-quality alloy steel material, integral forging and overall heat treatment process. High surface hardness effectively resists abrasion from gravel, mud and rugged working conditions, greatly extending service life.
2.Strong load-bearing and impact resistance:Reinforced overall structural design, thickened roller body and solid shaft. It can bear heavy machine weight and strong impact pressure during operation, not easy to deform or damage, suitable for heavy-duty construction scenarios.
3.Premium sealing performance, no oil leakag: Adopts advanced multi-layer sealing structure with dust-proof and waterproof design. It can effectively isolate sediment, muddy water and impurities, protect the internal bearing and lubricating oil, avoid oil leakage and early wear.
4.Precision size, perfect OEM replacement: Strict CNC precision machining, accurate dimensional tolerance. Fully compatible with Caterpillar E70B excavator chassis, direct installation without modification, stable operation and good matching performance.
5.Low maintenance and cost-effective: Stable overall performance, low failure rate and less later maintenance frequency. It reduces replacement times and equipment downtime, effectively lowering the comprehensive use cost for customers.
6. Stable operation, smooth walking performance: Fine internal assembly and strict dynamic balance inspection. Ensure flexible rotation of the track roller, reduce walking resistance, make the excavator walk more smoothly and reduce track wear.
E70B 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.
