The thin-section profile keeps the cross-section compact relative to bore diameter. Available sizes span from 6700 (10×15×3 mm \/ 0.39\"×0.59\"×0.12\") up to 6712 (60×75×7 mm \/ 2.36\"×2.95\"×0.28\"), covering a wide range of shaft diameters. Select variants include a double-side seal option for added contamination protection.\u003c\/p\u003e\n\u003cp\u003eTypical applications include bicycle bottom brackets and wheel hubs requiring corrosion-free thin section bearings, RC car and drone motor shafts where non-magnetic zirconia ceramic bearings reduce interference, and food processing or chemical handling equipment where stainless steel is insufficient and a full ceramic bearing replacement is required.\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 Fits standard 6700–6712 series bearing seats.

However, ceramic is more brittle than steel under sharp impact loads. They are well-suited for steady radial loads in motors, wheels, and spindles, but may not be the best choice for applications with heavy shock loading. Check the load rating for your specific size variant before substituting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill these bearings corrode in saltwater or chemical environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes — zirconia oxide is highly resistant to corrosion from water, salt spray, mild acids, and alkaline solutions. Unlike steel or even stainless steel bearings, ZrO₂ ceramic does not rust or pit in marine or chemical environments. This makes these bearings a common choice for kayak pedal drives, underwater ROVs, food processing conveyors, and laboratory equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings compatible with standard bearing pullers and press-fit tools?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes, the outer dimensions follow standard 6700-series metric sizing, so they fit the same housings and use the same installation tools as equivalent steel bearings. Use a bearing press or a correctly sized socket to press on the outer race only — never strike the inner race directly, as ceramic is more sensitive to point impact than steel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to lubricate these ceramic bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eOpen variants benefit from a light application of PTFE-based or ceramic-compatible grease, especially in high-speed applications. Avoid petroleum-based greases that may degrade ceramic retainers over time. The Double Side Seal variant comes pre-lubricated from the factory. In fully submerged or wash-down environments, many users run open ceramic bearings dry, as ZrO₂ has inherently low friction and does not require lubrication the way steel does.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I decide between buying 1 Pc, 2 Pcs, or 6 Pcs?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eOrder 1 Pc for a single repair or prototype test.
