Ceramic bearings as an important machine parts, owing to its unmatched metal bearing excellent performance, high temperature, super strength, etc. dominate the world in the new material. Over the past decade, in all areas of the national economy has been increasingly widely used.
Since the ceramic almost afraid of corrosion, so full of ceramic bearings suitable for corrosive media in harsh operating conditions. Since the density of ceramic rolling the ball lower than steel, more weight is much lighter, so rotating the outer ring of the centrifugal effect can be reduced 40%, thus greatly extended service life. Ceramics by thermal expansion and contraction smaller impact than steel, so when the bearing clearance must be allowed to bearing more severe temperature changes in the work environment. The elastic modulus of the ceramic steel high, not easily deformed by the force, it is beneficial to increase the working speed, and to achieve high accuracy.
Ceramic bearings with high temperature, cold, abrasion, corrosion, anti-magnetic insulation, self-lubricating oil, high-speed and other features. Can be used in extremely harsh environments and special conditions, can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, pumps, medical equipment, scientific research and national defense and military fields, is the application of new materials, high-tech products. Ceramic bearing rings and rolling all-ceramic materials, zirconium oxide (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic) three. Holder PTFE, nylon 66, polyether imide, zirconium oxide, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the surface of the ceramic bearing applications.
In the aerospace, marine, nuclear industry, petroleum, chemical, textile industry, machinery, metallurgy, electric power, food, locomotives, subway, high-speed machine tools and research areas such as defense and military technology requires high temperature, high-speed, cryogenic, flammable, explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, and other special conditions of work, ceramic bearings integral substitution being people gradually understanding.
With the processing technology continues to progress, the increasing level of technology, declining cost of ceramic bearings have been from the past only in some high precision and advanced within the field of small-scale applications, and gradually extended to the national economy in various industrial fields, the market price gradually approaching practical to achieve an acceptable level users, ceramic bearings wave of large-scale applications have been coming!
