    The difference between an excavator roller and a carrier wheel---Quanzhou excavator carrier wheel

    1. Roller: heavy bearing, high strength requirements, generally use sliding bearings; and the installation position is close to the ground, often immersed in rock, soil, mud water, high sealing requirements, tight sealing, high friction, not easy to rotate, only load-bearing can then be turned. ---Quanzhou excavator carrier wheel

    2. Carrier wheel: only bear the sinking weight of the upper track, and the bearing capacity is small (much smaller than the load of the bearing wheel). Generally, rolling bearings are used, and are installed above the track frame, away from the ground, not easy to be polluted, and have low sealing requirements. The seal is relatively loose, the friction force is small, it is easy to rotate, and the friction with the crawler chain is small to prevent mutual wear.

    If the rollers are used to replace the carrier rollers, the wheels will not rotate, and the track chain and the wheels will rub against each other, which is prone to premature wear. Therefore, the carrier rollers cannot be replaced by the carrier rollers. ---Quanzhou excavator carrier wheel
