Ceramic Bearing

As an important mechanical foundation, ceramic bearing has better performance than metal bearing, and its high temperature resistance and super strength are the first in the world of new materials.In the past ten years, it has been widely used in various fields of national economy and people's livelihood.

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.

Application:

Medical instruments, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.In aerospace, navigation, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high speed machine tools and scientific research and national defense military technology need to be in high temperature, high speed, cryogenic, inflammable, explosive, corrosive, vacuum, electrical insulation, non-magnetic, and other special work under the conditions of dry friction, the ceramic bearing indispensable alternative role is gradually known by people.

Classification

1.ZrO2

All ceramic bearings are featured with resistance to magnetoelectric insulation, wear-resistant and corrosion-resistant, oil-free and self-lubricating, high-temperature and high-cold resistance, which can be used in extremely harsh environments and special working conditions.

The ferrule is made of zirconia (ZrO2) ceramic material, the holder is made of PTFE (PTFE) as the standard configuration, and the glass fiber reinforced nylon 66 (rpa66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

2.Si3N4

Si3N4 ceramic material is used for bearing ring and rolling of silicon nitride (Si3N4). Rpa66-25, PEEK, PI, phenolic laminated bakelite tube can also be used.

The SiN4 all ceramic bearings are suitable for higher speed, load capacity and higher ambient temperature than the ZrO2 materials.

Precision ceramic bearings for high-speed, high-precision and high-rigidity spindles are also available, with the highest manufacturing accuracy UP to P4.

Founded in 1985, Nanjing Automobile Import and Export Co., Ltd. (hereinafter referred to as "NAIEC") is a wholly-owned subsidiary of Shanghai Automotive Industry Corporation (SAIC), which is one of the largest auto makers in China. NAIEC serves as an operation entity of SAIC's overseas business, focusing on import and export of various types of automobiles, auto parts, production equipment, etc. 

In the past over two decades, the company has exported over 100,000 units of different types of vehicle to more than 60 countries and regions. The exported products cover light trucks, buses, vans, pickups, etc. and are delivered in both CBU (completely-built-up) and KD (knocked-down) conditions. Collaborating with local distributors, NAIEC has built up vast sales and service networks in overseas markets and through them the company delivers quality products as well as professional services to end users. 

With the fast development of electric vehicles in both global and domestic markets, NAIEC has also started to prepare itself for this opportunity by acquiring new knowledge, adjusting organizations and adopting new business modes. EVs are taking up a growing share in the total export volume. 

We will always follow NAIEC culture -- to welcome with passion, to benefit with devotion. We are sincere to seek cooperation with friends from all over the world. Join us, let's make wonders together!
