Miniature full ceramic bearings for fishing reel
Full Ceramic Bearing ceramic bearings have good to excellent corrosion resistance, are nonmagnetic and, apart from silicon carbide,
are electrically insulating. Allceramic bearings can be used in high to very high temperatures if supplied without a cage (full complement).Electrical resistance: Si3N4 best, then ZrO2, then SIC which is conductive.
Full Ceramic Bearing have lower load and speed ratings than steel or hybrid bearings. The speeds are lower due to the lower precision and roundness of the rings and the loads are lower because the material is more brittle.
Under heavy loads and particularly heavy shock loads, there is a risk of cracking. For the same reason, great care should be taken with interference fits. Zirconia is the least brittle so it will handle shock loads and very small interference fits better than the other ceramic materials with silicon carbide being the most brittle. Shock loads should be avoided with allceramic bearings. Great care should be taken when using ceramic bearings (especially silicon nitride and silicon carbide) on steel shafts at high temperature due to the difference in expansion coefficient and the relative brittleness of ceramics.
full ceramic bearings Advantage
1.because ceramics are hardly afraid of corrosion, ceramic rolling bearings are suitable for working under harsh conditions full of corrosive media.
2.because the ceramic rolling ball has a lower density than steel and is much lighter in weight, the centrifugal effect of the
outer ring can be reduced by 40% when rotating, thus greatly extending its service life.
3.ceramics are less affected by heat expansion and cold shrinkage than steel, so the bearing can be allowed to work in an
environment where the temperature difference changes dramatically when the bearing clearance is constant.
4.as the elastic modulus of ceramics is higher than that of steel, it is not easy to deform under stress, so it is beneficial
to improve working speed and achieve higher accuracy.
