The supporting wheel of the excavator is the "load-bearing cornerstone" of the crawler walking system, which directly bears the weight of the whole machine and the vertical load during operation.By evenly dispersing the weight of the equipment to the track, it can avoid the deformation and fracture of the track due to excessive local stress, ensure the stability of the excavator in heavy duty operation, steep slope driving and other scenarios, and reduce the safety risks such as fuselage tilt and track falling off.
The track roller cooperates with the caterpillar, drive wheel and guide wheel to reduce the frictional resistance during the operation of the track by smooth rotation.High-quality track rollers can effectively alleviate the vibration caused by the contact between the track and the ground, avoid excessive wear of the chain track pin sleeve, reduce the probability of track loosening, clamping stagnation and other faults, and ensure the long-term and efficient operation of the equipment traveling mechanism.

The excavator in our mine has been working in the gravel pile all the year round, and the track roller used before has been worn badly in less than 2000 hours.".After replacing the high-hardness alloy track roller, it has been used for nearly 4000 hours, and the wear of the wheel surface is still very slight. It is really wear-resistant, which greatly reduces the frequency of shutdown and replacement, and has a high cost performance ratio.
As a maintenance provider, the most important thing is the adaptability and quality stability of track rollers.".This track roller is particularly accurate for Komatsu, Carter and other brand models, and there is no need for additional adjustment during installation. Customer feedback shows that the track runs smoothly without stuttering after installation.Moreover, the sealing is well done, there are few oil leakage problems, the after-sales response is timely, and the cooperation is very worry-free.
The three excavators of the construction team have replaced the track rollers of this company for almost a year. They have run from the earthwork to the muddy road section without a breakdown.".Before buying cheap miscellaneous brands, it won't take long to get stuck and abnormal noise. By contrast, the products here are reliable. Although the price is slightly higher, it's more cost-effective to count the cost of less maintenance and less missed work.
The project has purchased 20 sets of track rollers in batches, covering excavators of different tonnages.".The manufacturer not only provided a detailed model matching table, but also delivered the goods quickly. After the arrival of the goods, three sets of wear-resistant tests were conducted, and the results were better than expected.
