Why does the crane track rollerl wear？

The structure of the track roller is mainly divided into the wheel body, the support wheel shaft, the shaft sleeve, the sealing ring, the end cap,

If the hardness of the axle and sleeve of the heavy wheel you choose is not up to standard, there will be oil leakage less than a few days after installation

The crawler excavator walking mechanism bears all the weight of the excavator and is responsible for the driving function of the excavator.    The main form of damage is wear, which is concentrated in the following contact parts: the outer surface of the drive wheel teeth and the track pin sleeve: the guide wheel and the track track joint raceway surface;    Support wheel and track track section raceway surface;    Sprocket and track track joint raceway surface;    Track pin and pin sleeve contact surface;    Track plate with ground etc.
