Notice 1: All orders are final for this product. By purchasing you understand and agree with the terms described below.
Please Read / Important!
Attention! This bearing is currently experimental and limited in quantity. They truly feel amazing but there is a risk of damage if they are improperly installed due to their different construction (more infos below about their construction and in how to properly install them). We are transparent about the possibility of damage during the installation (or removal) of this experimental bearing, and it's up to you to decide to give them a try or not. We do not offer replacements or refunds in case of a broken bearing. If you can't accept this please refrain from purchasing this one. However if you feel like giving it a try please make sure to follow all the instructions here for the installation and you mostly should be fine to enjoy this little beast!
The UQH Dark Moon Bearing was custom made and adapted to specifically fit 12 bearing balls which makes makes it spin and feel super unique and amazing! This is the only 12 balls R188 bearing that we've ever made, and it really spins like a dream.
However, due to this adaptation, the outer race of this bearing is much thinner than usual and its inner race thicker than the standard. For this reason it is very important to be extra careful when installing or removing this bearing in order not to damage it, since some spinners may have a slightly tighter bearing hole than others (due to machining or excess of glue), so it's important to do a test before you install it. Here are some tips you should follow:
- First, choose the spinner you wish to install wisely since we recommend not swapping this bearing after you install it to avoid damage (it's possible to swap but the less you mess with it the better).
- Before installing the bearing, make sure your spinner bearing hole is clean and free of any glue. Do not use glue at first! Clean your spinner bearing hole with a Q-Tip soaked in acetone and make sure you remove any glue leftover and that all the area is very clean. Dry the spinner bearing hole with a paper towel if still wet from acetone.
- Next, using a proper bearing tool, like the Vega V1 or Vega V2 bearing tools (or another good one), align your bearing carefully with your spinner bearing hole. Make sure the bearing is not tilted or crocked. The bearing must lay flat and horizonal with your spinner and centered on the spinner bearing hole.
- Then, using your bearing tool, start slowly pushing the bearing into the spinner bearing hole and feel the pressure / tension of it. If you feel its hard to push it through, stop right away and do not install the bearing. In this case, try to install it on another spinner, repeating the steps above.
- If you feel there is not much pressure / tension while inserting the bearing you can proceed with the installation, always slowly to avoid damage.
- After installing you can push the bearing a bit with your finger and see if it moves. If you feel the bearing is too loose, you may then carefully remove the bearing and apply glue on your spinner bearing hole. Do not use too much glue! Most of the time only 2 tiny droplets (1mm or smaller) of glue is enough to hold a bearing. Make sure to spread the glue with a stick making the glue create a very thin "coat" around the bearing hole and only then proceed with the bearing re-installation, repeating all the steps above.
- Be very careful for small pieces of wet or dry glue falling inside the bearing as that may ruin your bearing spin forever. It is very important to carefully clean up any glue debris carefully pushing them away from your bearing, before you spin. This is a tip for any bearing installation and not just this specific bearing.
- You should have patience when going through all these steps, don't rush it and enjoy the process. If you feel you wouldn't have patience for this, maybe this bearing is not for you.
- Once your bearing is properly installed, just enjoy the ride! Your bearing should not be damaged by normal use so you can spin away. However as mentioned before, we recommend not swapping the bearing again to avoid damaging it on the process, so it would be best to keep this bearing installed in the first spinner you choose.

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!
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: Due to the ceramic materials and the manufacturing techniques used to make this specific bearing, it’s is common for the bearing to present small imperfections such as small marks on its body and cage. The PEEK cage slots may have slightly different sizes or offset. However, all these are considered normal characteristics for this bearing, and they should not affect the performance and spin quality of the bearing in any way.
If you encounter small marks like nicks and dings around the edges of the races, please know that this is normal for this specific bearing.
UQH does not consider any of these as "issues" and no refunds or cancellations are provided for bearing orders, unless the bearing is malfunctioning. More infos can be found in our refund and return policy page.
Notice 3: Please notice that we visually check every single bearing before they ship as well as test them for tolerance and give them a quick spin to make sure they are performing well and spinning freely.
Some bearings may be a bit dusty or gritty once you receive them, or sometimes they 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), but they should not have any mechanical faults.
For bearings that you may feel that are "dusty", 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.
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.
