"Hi, I am interested in your product. I am a new member for the longboard team.Do I really need to use bearing spacers?"---we received this mail in the last week

Yes. Despite seemingly not having any purpose, they perform a very important role. Assembled in the center of the wheel hub, bearing spacers align with the center ring of the bearings to allow tightening of the frame axles without the frame bending or pinching the wheels. This bending and/or pinching will prevent the wheel (or wheels) from spinning freely and affect performance. Bearing spacers also work to distribute the weight load to lessen stress and prolong the life of the bearings (and even the axles). To put it simply, they make wheels roll better and for longer.---I have a quick reply.

Soon, we received the next mail from the customer."Which size bearing spacers do I need?"

The axle size used on the skate frame (8mm or 6mm) determines which bearing spacers is to be used. Rather than trying to measure, a simple way to determine which is needed is to slide the frame axle through the center hole of a bearing. If the frame axle fills the entire space, it is an 8mm axle requiring 8mm floating bearing spacers . If it does not, it is a 6mm axle requiring 6mm long sleeve spacers that fill up the extra space. Besides, if you want to design a non-standard size spacer. we aslo can produce it for you.

NOTE: Bearing spacers and wheel hubs can vary in size due to manufacturing tolerances. Although not able to be seen by the naked eye, such tolerances can cause a wheel to make a clicking noise while skating or prevent it from spinning freely. Replacing the bearing spacer is most often the fix.
