Ceramic Ball Bearing Material
Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls.
Ceramic ball bearing material. Bearings made with ceramic materials fall into a specialty niche in the bearing industry. Jinli case durable 6805 ceramic bearing 1pc 15x45x9mm zro2 material 6805 ce full ceramic ball bearings sic 61805. Fully ceramic ball bearings tend to be more corrosion resistant more rigid and lighter in weight than most steel ball bearings. Benefits of the ceramic si3n4 silicon nitride ball bearing.
The most common arrangement is a hybrid bearing usually with stainless steel rings and ceramic balls. Additionally fully ceramic ball bearings are non magnetic which is useful for applications where this might be critical e g. Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Balls made from this material are hard up to rc78 and have a very smooth surface.
The ceramic material enables the bearing to run faster while maintaining a cooler operating temperature and simultaneously reducing noise and vibration. Lower coefficients and higher speeds are also possible and since they. Since these bearings are constructed from many materials they often operate in hybrid capacities. The most common ceramic material used is silicon nitride.
Ceramic ball bearings tend to be more corrosion resistant more rigid and lighter weight than most steel ball bearings. The weight of silicon nitride balls is only 40 of steel at 3 2 grams per cm cubic centimeter. Jinli case durable 2pcs 623 full zro2 ceramic ball bearing 3x10x4mm abec 9 zro2 zirconia ceramic ball bearings for ocean fishing reels size. Like the balls in hybrid bearings the rings in full ceramic bearings are typically manufactured from silicon nitride si 3 n 4 or zirconia zro 2.
Silicon nitride ceramic ball silicon nitride si 3 n 4 ceramic has become the standard ceramic ball material for hybrid ball bearings. We also build ceramic bearings i e bearings with ceramic races but they are not as common because they are less durable. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Typically bearings with rings and rolling elements of ceramic material are available as ball and roller bearings including sealed versions.
Main application areas are pumps and compressors where the bearings are lubricated by their own process liquid. This material is very hard over 2000 knoop and very wear resistant. Lower coefficients of friction and higher rpms are also possible and.
