These ZrO2 full ceramic thin wall ball bearings are engineered specifically for applications where standard steel simply fails — delivering reliable rotation in conditions that would degrade conventional bearings within weeks.\u003c\/p\u003e\n\u003cp\u003eEach bearing is manufactured from zirconium dioxide (ZrO2) ceramic throughout — races, balls, and cage — with no steel components. The thin-wall series spans models 6700 through 6708, covering inner diameters from 10 mm (0.394 in) to 40 mm (1.575 in), outer diameters from 15 mm (0.591 in) to 50 mm (1.969 in), and heights from 3 mm (0.118 in) to 6 mm (0.236 in). Available in packs of 1, 2, 3, or 5 pieces to match your project scale.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include food-processing machinery requiring washdown resistance, medical and laboratory equipment demanding non-magnetic and non-conductive rotating elements, RC vehicles and drones where weight savings improve performance, and semiconductor or clean-room tooling where metallic contamination is unacceptable. The thin-wall geometry also makes these ZrO2 ceramic thin wall bearings ideal for compact spindle designs where radial space is constrained.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Dimensionally interchangeable with standard 6700–6708 series deep-groove ball bearing envelopes.

There are no steel components. This distinguishes them from hybrid ceramic bearings, which use ceramic balls in steel races.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do ZrO2 ceramic bearings resist corrosion compared to steel or hybrid bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eZirconium dioxide is chemically inert to most acids, alkalis, and salt solutions that would oxidize or pit steel races. Unlike hybrid bearings where steel races remain vulnerable to corrosion, full ceramic bearings maintain their surface finish and dimensional accuracy even after prolonged exposure to aggressive media — making them suitable for washdown, marine, and chemical-processing environments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use these bearings in high-speed spindle or drone applications?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. The thin-wall geometry reduces rotating mass, and ZrO2 ceramic has a lower density than steel (approximately 6.0 g\/cm³ vs. 7.8 g\/cm³), which lowers centrifugal loading on the balls at high RPM. These characteristics make the 6700–6708 series a common choice for RC motors, drone frames, and compact high-speed spindles. Confirm your specific speed rating requirement with us if operating near the upper RPM limit of your design.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo these bearings require lubrication?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eZrO2 ceramic has lower surface friction than steel and can operate with minimal or no lubrication in many dry or clean environments. However, for high-load or high-speed applications, a compatible ceramic-safe grease or oil is recommended to extend service life. Avoid petroleum-based greases that may degrade certain cage materials — contact us to confirm the lubrication specification for your specific variant.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings dimensionally compatible with standard 6700-series steel bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. The 6700–6708 ZrO2 ceramic bearings follow the same ID, OD, and width envelope as standard deep-groove ball bearings in the 6700 series, making them drop-in replacements in most housings. Always verify the exact bore, outer diameter, and width of your existing bearing against the variant dimensions listed before ordering, as some thin-wall variants (e.g., the 3 mm vs. 4 mm height options for 6700) differ from the most common catalog dimensions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the two 6700 variants (3 mm and 4 mm height)?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eBoth share the same 10 mm ID and 15 mm OD but differ in width: the 6700 (10×15×3mm) is the standard thin-wall profile, while the 6700 (10×15×4mm) offers a slightly wider raceway that can support marginally higher axial and radial loads.
