Advanced Hard wearing extend service life by 50%

Due to the constant rolling friction between the roller and the flag of the crawler and to support the weight of the crane body, the hardness, toughness and wear resistance of the track roller are necessary factors to ensure the service life. After precise overall quenching and tempering, the hardness of the entire bottom roller body conforms to the original technical standard. Through a series of inspections such as tensile test, metallographic inspection, magnetic particle inspection, etc., the quality of each batch of lower rollers is guaranteed to be stable.

Fine copper bushing increases durability

Use thickened high-quality copper bushings will inevitably increase some costs, but in the long-term use, it will be found that the wear resistance of the copper bushing and the shaft increases significantly, the possibility of oil leakage is greatly reduced, and the maintenance cost downtime period is reduced, the use benefits it brings far outweigh the increased costs. Good internal materials are easy to ignore when purchasing, but they are the core that affects the overall service life of the track rollers. We firmly believe that details determine quality.
