1.High precision bearings,P4 ,P5 and P6.
2.Rings are made of refined Chrome steel.stainless steel 440C
3.Cage:Peek & PTFE cage .(can assure constant working under 250 centigrade)and peek cage also is the ideal cage for the high speed as it can provide the lubrication during bearing working, and it has the property of self-lubrications.However for normal applications, steel cage and Nylon cage is enough.
4. Balls: we use G3,G5 high precision Si3N4 ball for the high speed.
5. Radial clearance: Normal C0,or C3.
6.Not only for the high speed, but also Hybrid bearings has the
insulation functions. Hence for the small size of bore dia.40mm ,
also can be used for the insulation bearing purpose.
7.Full ball hybrid also can be produce as per our production picture.
Allceramic 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.
Allceramic bearings 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 c
are 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.
