Structural design advantages
Multi-layer sealed structure
The PC2000 track roller uses 2-3 lip seals, equipped with a dust-excluding lip that specifically removes dust and dirt; some designs include a spring-loaded pressure-sealing structure that can compensate for seal wear and effectively block external contaminants from entering.
Sealing Materials
Sealing rings are selected from fluorine rubber (FPM) or hydrogenated nitrile butadiene rubber (HNBR), featuring oil resistance, high-temperature resistance, and anti-aging properties; the sealing system also has anti-leakage functionality, preventing internal lubricating oils from leaking, suitable for complex operating environments.
Long-lasting lubrication
It is pre-lubricated with specialized high-performance grease, suitable for wide temperature ranges (-45°C to 150°C), high-load, low-speed heavy-duty conditions; the large internal oil storage space and the grease's strong anti-oxidation ability ensure it does not degrade over long-term use.
Quality assurance
All PC2000 track rollers undergo low-pressure airtightness testing before leaving the factory to ensure sealing performance; the special alloy material has self-lubricating properties, ensuring basic operation even under extreme lubrication deficiencies.
High performance products
Stable Operation
The PC2000 track roller can stably support the equipment for smooth operation; it has low rolling resistance and moves smoothly on track guides or track plates; it can limit track lateral slippage, withstand large lateral forces, and ensure stable travel direction; during steering, it forces the track to slide smoothly, and responds quickly to emergency braking, demonstrating excellent dynamic performance.
Adaptation to all scenarios
The product is suitable for multiple working conditions and rough terrain such as mines, construction sites, wetlands, etc., and has stable performance at high temperatures, low temperatures, and different altitudes. It is not easy to deform and damage in heavy load and high-intensity operations, and can work continuously for a long time; Good adaptability to the ground and strong adhesion under different soil conditions.
Collaborative Optimization
PC2000 track roller cooperates with the track and equipment power transmission to reduce track wear, extend its life, and improve the overall performance of the equipment. Low vibration and low noise to protect equipment components and improve operator comfort. The moment of inertia is reasonable, the energy loss is low, and the impact on the driving speed is small, ensuring the efficiency and economy of the operation.
Safety and adaptability
Parts compatible
Our PC2000 track roller is compatible with PC2000 excavators and improved models of the same brand and tonnage series, and can be compatible with the track chains of different manufacturers without modifying the equipment track system.
It can be matched with different types of track shoes, and can be adapted to the PC2000 equipment equipped with breakers and grabs after modification to withstand the new load and expand the applicable scenarios.
Environment and working conditions
It can work stably in the cold of -30°C to 50°C and high temperatures at different altitudes; It is suitable for hardened concrete ground, soft mud soil and other hardness grounds to avoid abnormal wear of the wheel body.
It can be equipped with a variety of shock absorbing devices and lubricating oil models, and can adapt to different walking speed modes such as high-speed transfer and low-speed heavy load of equipment to meet various operation needs.
Structural Protection
Our PC2000 track roller wheel edge arc transition is anti-scratch, and the surface coating is anti-static to adapt to flammable and explosive environments, and the weight distribution is uniform to reduce the risk of equipment rollover.
The track rollers are equipped with protective baffles to block debris, the overload protection structure to release excess pressure, and the anti-loosening design of connecting bolts to avoid falling off, ensuring the safety of operation and equipment structure.
Operation and maintenance
The sealing system is leak-proof, the high-temperature stable lubricating oil is anti-overheating and spontaneous combustion, the wheel body anti-slip design avoids track slippage, and the operating noise is controlled within a safe range to protect the operator's hearing.
The maintenance and disassembly process complies with safety specifications, and the manufacturer provides complete safety instructions to guide operation and emergency treatment to reduce maintenance risks.

Q＆A
Are PC2000 track rollers prone to oil leaks? If so, how can I fix it?
A: Under normal circumstances, oil leakage is uncommon with PC2000 track rollers, provided the manufacturing process meets standards and the seals are reliable. Internal features of the track rollers, such as sliding ring seals made of highly elastic, high-quality materials, prevent oil leakage. However, if substandard seals are used, errors are made during assembly, or the track rollers are subjected to prolonged operation in harsh environments, resulting in heavy sediment erosion, oil leakage may occur.
Once an oil leak is discovered, the seals must be checked first. If the seal sleeve or sealing rubber ring is aged, deformed, scratched, or cracked, it must be replaced promptly. Secondly, check whether the spring force is insufficient. If there is a problem, replace the spring. At the same time, repair and level the warped parts of the pressure ring and remove the sharp edges. Thirdly, check whether the large and small sealing rings are in close contact. If not, regrind them to have a uniform and continuous grinding ring band, and pay attention to the consistency of the ring thickness. In addition, problems such as axle bending, out of roundness, or neck wear, as well as wear on the supporting wheel hub and sealing housing mating belt must all be repaired. During the installation process, it is also necessary to strictly inspect the parts according to the technical requirements, keep them clean, and prevent impurities from entering the installation surface.
Is the installation of the PC2000 roller complex? What are the requirements for the installer?
A: The installation of PC2000 track rollers requires a certain level of expertise, but it is not very complicated for professional installers familiar with the chassis structure of construction machinery.
The installation process must be carried out strictly in accordance with the relevant installation manual and technical specifications.
Before installation, the installer must carefully inspect the track rollers and their associated components to ensure they are free of damage, deformation, or other issues. During installation, the components must be strictly inspected according to their technical specifications, and the mounting area must be kept clean to prevent impurities from entering the mounting surface, especially the sealing surface of the sealing ring. Even tiny dust particles can damage the seal and cause oil leakage. After installation, commissioning and inspection are required to ensure the track rollers are securely mounted, rotate freely, and are not stuck.
What are the advantages of our PC2000 track rollers compared to similar models from other brands?
A: Our PC2000 track rollers offer significant advantages over similar models from other brands. The wheel bodies of PC2000 track rollers are typically forged from high-wear-resistant boron steel, such as 40MnB2, while the main shafts are constructed from 50Mn high-quality carbon structural steel.
This combination of steels gives the track rollers greater strength and hardness, making them more wear-resistant and impact-resistant than competing products made from ordinary steel.
This allows them to withstand heavier loads and reduces premature wear and damage caused by material issues. In terms of sealing structure design, the PC2000 track roller adopts advanced sliding ring seals and other structures, and the seals are made of high-elasticity, high-quality materials, which can better resist the intrusion of impurities such as dust, mud and water, and effectively reduce the risk of oil leakage. Compared with some brands of track rollers with poor sealing performance and prone to oil leakage, it can greatly reduce a series of failures caused by oil leakage and reduce maintenance costs.
