A: The cleaning of the skateboard bearing is very simple. Remove thebearing from the plate, wipe off the oil and dirt on the bearing with a paper towel, and wipe off the inner wall of the wheel. Changing the wheel from left to right and back is good for the smoothness of the bearing. It is cleaned about once a week. The high temperature generated by the rotation of the bearing when the plate is used makes the rubber of the wheel and the bearing wall close to each other, which makes it inconvenient to change the wheel or change the bearing. To avoid trouble, clean the bearings at the same time.
