Ceramic components within bearings, whether the rolling elements or the rings as well, are suitable for extreme temperature and/or low lubrication situations. Their cost, although dramatically reduced from two or three years ago, is still high when compared with a correctly designed steel equivalent. AHR can provide you unbiased guidance on whether you need a ceramic solution. In many cases we have advised customers not to use ceramic, not only due to its cost but in many examples the expansion characteristics are not always suitable for many applications.
