The difference between the industrial bearing and skateboard bearing
Environmental differences
Bearings designed specifically for skateboards and industrial bearing are of the same size, but the working environment of the two is quite different, so the performance to be satisfied is also far from satisfactory. Industrial bearings are generally working in a high-speed, stable, vibration-free and dust-free environment (mostly used on motors). The working environment of skateboard bearings is outdoor, outdoor dust, water, and the impact of the user bouncing on the bearings Force, there is also a lot of side torsion brought about by the lateral torsion, making skateboard bearings must overcome these harsh working conditions, of course, this is the reason industrial bearing cannot meet the needs of the skateboard.
Precision control
One data standard for industrial bearings is ABEC, and ABEC systems include 1, 3, 5, 7, and 9. The higher the level, the smaller the allowable tolerance and the more precise the bearing. Skateboard bearings do not require the use of high-precision motor bearings. Therefore, the precision of the slide bearing is -7, which is enough, and it does not make any sense for the user to improve the accuracy of the slide bearing.
