How to clean skateboard bearings？

More than 34 years of bearing design and manufacturing years, BONES bearing development so far, is one of the best-selling slide bearing in the United States, the use of unique rubber protection, convenient bearing cleaning, reduce bearing friction, high-speed nylon support to provide greater speed for the bearing.

As the name suggests, is to play the role of dust.  Dustproof cover can reduce dust and other debris into the bearing to a certain extent, delaying the service life of the bearing.  Not all skaters like the dust cap, some like to remove the dust cap, although the noise will be louder, but the slide quickly.

The sliding plate bearing we use is a rolling bearing with a rolling body, and is also a deep groove ball bearing in rolling bearings. The size and code is 608Z (according to the industrial division, especially refers to the model size).  The common rolling body of sliding plate bearings is steel ball, but also ceramic ball. Generally speaking, each set of bearings is made of 7 steel balls/ceramic balls as a group of 

rolling body, mounted between the inner and outer rings.  

Cage is to make the rolling body in the bearing evenly separated, so that each steel ball can keep in the appropriate position of normal rolling, and play a role in preventing the rolling body falling off.  

In addition, each set of bearings (8) are independent packages. The speed, friction coefficient, material and technological level of the 8 bearings are similar. In order to ensure the maximum efficiency of each set of bearings, they are placed in a packaging box.  To put it another way, when your bearing blows, it is best to replace the rest of the bearing.
