51101CE flat thrust ball bearing

Advantages of ceramic bearings:

First, since ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operating in harsh conditions full of corrosive media.

Second, since the density of ceramic rolling balls is lower than that of steel and the weight is much lighter, the centrifugal effect on the outer ring during rotation can be reduced by 40%, thereby greatly extending the service life.

Third, ceramics are less affected by thermal expansion and contraction than steel. Therefore, when the bearing clearance is constant, the bearing can be allowed to work in an environment with drastic temperature changes.

Fourth, since the elastic modulus of ceramics is higher than that of steel, it is not easily deformed when subjected to force, so it is conducive to increasing the working speed and achieving higher precision.

Uses of ceramic bearings:

Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, antimagnetic electrical insulation, oil-free self-lubrication, and high speed. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and national defense and military fields. High-tech products using new materials.

The rings and rolling elements of ceramic bearings are made of all-ceramic materials, including zirconium oxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconium oxide, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the application range of ceramic bearings.

Application areas of ceramic bearings:

Medical equipment, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.

In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electric power, food, locomotives, subways, high-speed machine tools and scientific research on national defense and military technology, it is necessary to operate at high temperatures, high speeds, cryogenic temperatures, flammable, Working under special working conditions such as explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, etc., the indispensable alternative role of ceramic bearings is gradually being recognized.

With the continuous advancement of processing technology and the increasing level of craftsmanship, the cost of ceramic bearings continues to decrease. In the past, it has been only used in a small range of high-end, precision and cutting-edge fields, and has gradually been extended to various industrial fields of the national economy. The market price of ceramic bearings It is also gradually approaching practicality and reaching a level acceptable to users. The wave of large-scale application of ceramic bearings has come!
