Full Ceramic Ball Bearings

.

Full Ceramic Ball Bearings are an essential component in many industrial and other types of machinery. They are a type of bearing that is made entirely from ceramic materials, including the balls, rings, and cages. Unlike traditional bearings, full ceramic ball bearings offer a wide range of benefits that can help to improve the efficiency, performance, and lifespan of machinery.

One of the most notable advantages of full ceramic ball bearings is their high-level durability. Ceramic materials are much harder than steel, making them more resistant to wear and tear over time. This means that full ceramic ball bearings can last much longer than conventional bearings and are less likely to require replacement over time. As a result, they offer a more cost-effective and practical solution to businesses and industrial facilities.

Another advantage of full ceramic ball bearings is that they operate with less friction than other types of bearings. This is because ceramic materials have a much smoother surface finish than metal, which can help to reduce the amount of friction and heat generated during use. This, in turn, can help to lower operating temperatures and reduce energy consumption, leading to cost savings for businesses and a longer operating life for machinery.

Full ceramic ball bearings are also highly resistant to corrosion, making them an ideal solution for use in harsh environments. This is particularly important for businesses operating in industries such as marine or chemical processing, where equipment is often exposed to harsh chemicals, saltwater, or other corrosive elements. With full ceramic ball bearings, businesses can ensure that their machinery continues to operate efficiently and reliably, even in the most challenging conditions.

Aside from their high-level durability, low friction, and corrosion resistance, full ceramic ball bearings are also increasingly popular due to their aesthetic appeal. The unique, glossy finish of ceramic materials is highly attractive and can add a touch of class and style to machinery and equipment.

In conclusion, Full Ceramic Ball Bearings are an excellent choice for businesses looking for a high-quality, reliable, and cost-effective bearing solution. With their high-level durability, low friction, and corrosion resistance, they can help to improve the efficiency, performance, and lifespan of machinery, leading to cost savings and a more productive work environment.

● Introduction

The ferrules and balls of full ceramic ball bearings are made of zirconia ceramics, silicon nitride ceramics or silicon carbide ceramics. It is a very important part in mechanical equipment, which has wear resistance and chemical resistance, and can withstand wear and deformation caused by high temperature and high speed. The density of ceramic balls in the bearing is much lower than that of metal balls, which can reduce the centrifugal friction of the outer ring of the bearing, and the ceramic itself can be self-lubricating, which can reduce the speed drop due to the resistance caused by the lack of lubricating oil, so it can be effectively replace metal bearings in some extreme environments. Ceramics are less affected by thermal expansion and contraction than steel, so when the bearing clearance is constant, the ceramic ball bearings can be allowed to work in an environment where the temperature difference changes more drastically. The elastic modulus of ceramics is higher than that of steel, and it is not easy to deform when subjected to force, so it is beneficial to improve the working speed and achieve higher precision. Full ceramic ball bearings have excellent characteristics such as high speed, high temperature resistance, non-magnetic, insulation, self-lubricating, light weight, wear resistance, corrosion resistance, etc., suitable for strong acid, strong alkali, inorganic, organic salt, seawater environment.

Full ceramic bearings are widely used in electronic equipment, chemical machinery, shipbuilding, medical equipment, precision instruments and other fields.

● Production Details

◆ Ceramic materials

There are many types and manufacturing processes of ceramic materials, but it has been proved by experiments that hot pressing silicon nitride (HIPSN) or hot isostatic Si3N4 (HIPSN) are compactors with good performance and are most suitable for manufacturing high-performance bearings. Hot-pressed Si3N4 ceramics are mixed evenly and loaded into a graphite mold with Si3N4 powder and dense additives. Then a mechanical pressure of 30~50MPa is applied to a high temperature of 1700~1800C at the same time, and sintered and formed after insulation for 1 to 2 hours. In this way, it can be made into plate-shaped or rod-shaped blanks, which are often used to make bearing rings, and are not suitable for mass production of ceramic balls.

◆ Processing of ceramic inner rings

The thermal isostatic pressure method can improve the shape and dimensional accuracy of the ball blank and make the material dense. The process is to pre-prefabine Si3N4 powder with an average particle size of not more than 1um into a globular embryo. At this time, the spherical is loose and easy to process. Then it is sintered at a high temperature of 1,700 degrees in high pressure, using the principle of liquid phase sintering to make it dense, and the globlastic embryo obtained without pressure sintering is poor. At present, the thermal isostatic pressure (HIP) method is the best way to obtain dense spherical billets. It can be used for large-scale production of rolling bearing ceramic ball blanks. In order to obtain uniform and fine blank microstructure with few defects, it is necessary to strictly ensure the purity of Si3N4 powder and control the content of various impurities, and monitor the particle size and shape of the powder. Otherwise, a thick microstructure containing stomata and cracks will be formed, which seriously affects its mechanical properties, especially the fatigue life will be very low.

● Processing of Ceramic Materials

The processing of ceramic bearing rings includes the outer ring surface, inner ring surface, end surface and channel processing. All surfaces are processed with diamond abrasive tools. During rough grinding, a large grinding ratio can be obtained by selecting metal binder grinding wheels. When grinding, the resin binder grinding wheel can obtain a good quality surface. However, the grinding wheel should be trimped frequently during grinding. In addition to grinding, the processing of the channel should also be grinded and super-precision. It is not only necessary to ensure the geometric accuracy of the size and surface roughness, but also to remove the metamorphic layer on the surface of the channel to ensure the integrity of the workpiece. Only in this way can the bearing have a long life. Machine tools used for machining should have high stiffness.
