However, ceramic is more brittle than steel under impact or shock loads. These bearings are best suited for smooth, continuous rotation rather than applications with heavy shock loading or press-fit interference that could crack the race.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo these bearings need lubrication?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eFull ceramic ZrO2 bearings can run dry because ceramic-on-ceramic contact has inherently low friction and does not require oil or grease for corrosion protection. In very high-speed or high-load applications, a small amount of PTFE-based dry lubricant can extend service life. Avoid petroleum-based greases at temperatures above 200°C as they will carbonize.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings resistant to chemicals and corrosion?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. Zirconium dioxide is chemically inert to most acids (including hydrochloric and sulfuric acid at moderate concentrations), alkalis, and saltwater.

Because ZrO2 ceramic contains no ferrous metals, these bearings are fully non-magnetic and will not be attracted to or disturbed by strong magnetic fields.
