Warning!

Ceramic bearings can break! In case your bearing breaks during installation or removal, we do not offer replacements or refunds, so be very careful when installing or removing them, and pay attention to the following:

Be careful when installing or uninstalling ceramic bearings as they may break if your spinner bearing hole is too tight for them. Ceramic is a very brittle and hard material and it has no room to flex or bend. If the bearing hole of your spinner is too tight, i.e if it has too much glue, or dry glue leftover from a previous installation, or if your spinner was machined with a bearing hole slightly smaller than the standard, it is very important that you do not force push your bearing in or out. If you feel a strong resistance when installing or removing your ceramic bearing, stop immediately. You may want to make sure your bearing hole is very clean, with no glue residues before installing your bearing. If glue is necessary then you may apply a little bit of glue in the spinner bearing hole walls (never on the bearing) and try again. If you still feel it’s too tight for your ceramic bearing, do not install it on that spinner. Again, we do not offer replacements or refunds if you break your bearing!

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.
