Attention: When using any type of glue to install your bearings, be very careful not to drop any small drop of glue inside the bearing tracks. Also pay attention to small flakes of dry glue once you are installing or uninstalling your bearings as they may fall into the bearing tracks and could potentially ruin your bearing spins. We QC and spin test every bearing before they leave the Shop to make sure they spin nice and freely, and we do not take responsibility for user error, nor issue replacements for this reason. If you have any questions on how to install your bearings please contact us and we would be glad to help!

Notice 2: Please notice that we do a QC test for ALL bearings in our shop right once we receive them from the manufacturer and another QC right before shipping it to the customer. We do visual checks for marks or defects, and we check for spin quality and tolerance for every single one of them.

We highly recommend that you give your bearing a quick spin using your fingers or the end of a pen or straw first BEFORE you install it on your spinner so you can check the spin characteristic. We also recommend that before you install any bearing on your spinner, you always try to push it into it without using any kind of glue or adhesive at first. If it feels tight enough, then you wont need to add any glue.

Sometimes if the bearing is not installed correctly, like for example if some glue (wet or dry leftover from a previous installation) gets inside the bearing cage and balls, it can destroy the bearing or get it to sound very dirty and gritty. Make sure you are very careful when installing your bearings. You can find a step by step on how to install your bearings in the description of our 641 Bearings Glue here:

Notice 3: Sometimes some bearings may present small marks or tiny dings on the edges of the races (specially for full ceramic ones due to the brittleness of the material), If you encounter small marks like nicks and dings around the edges of the races, please know that we consider that as normal since it should not affect the performance of the bearing in any way. We will never ship a bearing if the bearing has major defects like big marks or has a faulty spin and since we double QC each one, that is very very rare to happen.

For bearings that you may feel that are "dusty" or gritty, please use a compressed air can on the bearing while holding it with a straw. Make sure to make the bearing spin as fast as possible for around 5 seconds. That should be enough to get rid of any tiny particles, dust or lint that may be sitting between the bearing balls and cage. We do not recommend the use of liquids or soap for any bearings.

Bearings are consumables! They should last you many years if enough care and maintenance is given, however they may eventually stop performing well specially if they get dirty or wet for some reason. So please keep in mind that at this time, we do NOT offer refunds for bearings (unless there is clear mechanical or manufacturing fault upon receiving them) and all orders are final. If you have any questions please email us or visit our “Refund & Return Policy" page.
