D60 double 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 Load Capacity
Built from high-quality 35MnB steel, adopting integrated forging and casting technology. This robust structure enables the D60 single track roller to reliably bear the heavy weight of the dozer, ensuring stable operation even under high-load working conditions.
2. Superior Wear Resistance
The surface of the track roller is subjected to professional hardening treatment, reaching a hardness of HRC 52–58 with a hardening depth of 8–12 mm. This excellent wear resistance effectively extends the service life of the product, making it suitable for long-term use in harsh and abrasive working environments such as construction sites and mines.
3. Durable Sealing System
Equipped with an advanced floating seal combined with high-quality oil seals, the D60 single track roller forms a multi-layer protection barrier. It can effectively prevent the ingress of water, dust, mud and other impurities, greatly reducing the risk of oil leakage and mechanical failures, and reducing daily maintenance workload.
4. Precision Fit & Smooth Operation
The dimensions of the track roller are processed by CNC machine tools, ensuring high precision and perfect compatibility with Komatsu D60 series dozers (including A-6/A-7/E-7/F-8/P-6 and other models). At the same time, it features low rolling resistance, which can improve the travel efficiency of the dozer and ensure smooth and stable operation.
5. Heavy-Duty Construction
The shaft and bushing of the D60 single track roller adopt a reinforced design, which has strong resistance to bending and impact. It can adapt to the complex and harsh working conditions of mining, construction, and rough terrain, avoiding damage caused by accidental collisions or uneven ground.
6. Cost-Effective & Low Maintenance
The extended wear life of the track roller reduces the frequency of replacement and equipment downtime, saving replacement costs. In addition, its simple and reasonable structure makes installation and disassembly convenient, reducing labor costs and improving work efficiency.
7. Reliable Performance in Tough Environments
The D60 single track roller maintains stable performance in various harsh environments, including muddy land, rocky areas, and extreme temperatures. It can provide consistent traction and track guidance for the dozer, ensuring the normal progress of the project without being affected by the environment.
D60 double 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.
