There are two types of ceramic bearings (Si3N4 Silicon Nitride, and the ZrO2 Zirconium Oxide). Then you have full or hybrid. A full means that all components of the bearing are made from those elements. The hybrids will usually have the ceramic balls and the rings/races are made from some other material. Just make sure the size matches to the existing bearing in your spinner if you're buying a replacement online. \r\n\r\nRegards,\r\nNate","subreddit_name":"FidgetSpinners","author":"fidgetmonkeys"},{"body":"As far as the bearing goes, I've seen them from $10 [\\(vxb via amazon\\)](https://www.amazon.com/VXB-Ceramic-Miniature-Bearing-8x22x7/dp/B01JKBUR1Q/ref=sr_1_fkmr1_1?ie=UTF8\u0026amp;qid=1487984939\u0026amp;sr=8-1-fkmr1\u0026amp;keywords=608+Zr02%2FSi3N4+Full+Ceramic) all the to the $100s. I personally haven't bought any full ceramic ones yet, but I'm waiting on some of the spinners I ordered to arrive so I might be looking to replace them if I'm not content with the ones that come in the unit.","subreddit_name":"FidgetSpinners","author":"G-wow"},{"body":"Or $9.95 with free shipping on [Amazon](https://www.amazon.com/gp/product/B01JKBUR1Q/).","subreddit_name":"FidgetSpinners","author":"fastlerner"},{"body":"Can't say for sure without knowing what size/specs, it will vary by brand as well, but [this one](https://www.amazon.com/dp/B01JKBUR1Q/ref=cm_sw_r_sms_c_api_QELazbZVE9B9F)  I picked at random on Amazon says it's 0.6 ounces most will be around this.

Not too bad","subreddit_name":"3Dprinting","author":"tmprof"},{"body":"Well, they'll work, but they'll probably spin for 10 seconds max. If you're getting a 3d printer spinner, you can get those cheap bearings for the edge holes and then get 1 good center bearing. I'd go with [this one](https://www.amazon.com/Ceramic-Miniature-Bearing-8x22x7-Width/dp/B01JKBUR1Q/ref=sr_1_3?ie=UTF8\u0026amp;qid=1480639221\u0026amp;sr=8-3\u0026amp;keywords=full+ceramic+bearing). May be more than you wanted to pay but off brand bearings won't spin long at all","subreddit_name":"fidgettoys","author":"dumbnotdumber"}]}
