Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties. It is used in abrasives, refractories, ceramics, and numerous high-performance applications. The material can also be made an electrical conductor and has applications in resistance heating, flame igniters and electronic components. Structural and wear applications are constantly developing.

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities. Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600°C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces. The electrical conduction of the material has lead to its use in resistance heating elements for electric furnaces, and as a key component in thermistors (temperature variable resistors) and in varistors (voltage variable resistors).

TypeCeramic Speed Bearings

Ceramic Speed Bearings from Denmark feature rolling balls made of a ceramic material. The Ceramic Speed balls are constructed of Grade 3 Silicon Nitride, the highest grade for hybrid ceramic bearing, which meets or exceeds NASA engineering standards. Using Ceramic Speed bearings in hubs, bottom brackets, and pulleys will reduce friction. By reducing the coefficient of friction, you can accelerate faster and maintain speed with less power input. Benefits of ceramic bearings: Ceramic bearings have 10% less friction than steel bearings. Bearings are extremely wear resistant because ceramic material is much harder than the hardest steel bearings. Silicon nitride balls are 60% lighter than steel balls. Safe operation even when using low amounts lubricant, which reduces the viscous drag friction from lubricant. When used with special seals and lubrication, the friction in ceramic bearings can be 20-30 times lower than steel bearings with standard friction seals and standard lubrication. Wheelbuilder uses Ceramic Speed hybrid ceramic bearings for all high-end applications. Compared to all steel bearings, they have lower friction, lighter weight and longer service life. They are also less susceptible to failures caused by dirt, dust and poor lubrication. Ceramic bearing upgrades can be made to the main hub body as well as the freehub body. Ceramics provide the most significant gain when used in the main hub body because these bearings carry the primary rider loads. Ceramic Speed develop and produce ball bearings which create significant economic advantages when used in industrial applications. For the past 10 years we have worked on developing and improving bearing performance, using high-tech components and today we are the world leaders in our field. We have specialised in producing hybrid bearings for 2 areas: sport and industry. All bearings are handmade in Denmark using components from the best suppliers in the world. We have many years of experience developing hybrid bearing solutions for industrial applications, using ceramic balls of a unique quality together with other specially developed components. Ceramic Speed bearings have unique properties, which can solve challenges where ordinary steel bearings arent good enough. In addition to this Ceramic Speed bearings have a lifetime which is 4-8 times longer than steel bearings; this simplifies maintenance and increases up time in industrial production. Bearings that last! The cost of bearings themselves forms a very small part of the total cost of the machines in which they are installed - both in new machinery and in maintenance. However, the cost of maintaining or replacing bearings can be much higher. This means that bearings that last longer can reduce operating costs significantly. Share on facebook

Ceramic Insert Bearings are made entirely of ceramic material and are superior to common Steel Insert Bearings in many ways. 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. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC.)

Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds. Full Ceramic bearings can have a retainer or full complement of balls, retainer materials used are PEEk and PTFE.

Full Ceramic Insert Bearings can continue to operate under extremely high temperatures and are capable of operating up to 1800 Deg. F. Ceramic is much lighter than steel and many bearings are 1/3 the weight of a comparable steel bearing. Full Ceramic Insert Bearings are highly corrosion resistant and will stand up to most common acids, they will not corrode in exposure to water or salt water. And finally Full Ceramic Insert Bearings are non-conductive.

Full Ceramic Insert Bearings and wide inner ring bearings are used for mounting on shafts without the need for shoulders or adapters. The bearing is locked in place through setscrews or a locking collar. The inner ring usually extends on both sides of the bearing to provide extra shaft support, but some styles only extend on one side. Sometimes Full Ceramic Insert Bearings are simply standard radial bearings that fit into a housing and these bearings may be purchased as stand-alone products to use as replacements. While standard radial ball bearings must be pressed into a machined shaft, using special installation tools, insert bearings can be slip fit directly onto the shaft.

Electrical pitting often occurs in bearings used in electrical equipment, such as motors and power generators, as a result of current leakage. An electrical current present near a bearing can flow to the inside of the bearing, causing sparks that damage the rolling contact surface, ultimately leading to bearing failure. This electrical pitting and can be prevented with coated bearings or ceramic hybrid bearings.

NTN Coated Bearings:

NTN’s MEGAOHM™ Series of insulated bearings has been specifically designed to counteract electrical pitting. These bearings are available in both ceramic and resin versions that are suited to a variety of applications. Coating the outer ring of the bearing provides a barrier (capable of resisting at least 100 M at 500 VDC) against any stray currents that would pass through the bearing.

MEGAOHM™ Series bearings are featured as OEM equipment on wind turbine generators, traction motors for railway cars, and variable speed electric motors in wastewater treatment facilities.

NTN Ceramic Hybrid Bearings:

For especially problematic applications, NTN offers ceramic hybrid bearings. Using conventional steel inner and outer rings, silicon nitride rolling elements provide excellent electrical insulation while reducing rotating mass and improving heat dissipation.

Si3N4 Full ceramic bearing of full complement balls has an add-ball gap on its side. Because using no retainer design, the bearing is able to install more ceramic balls than the standard construction, so the heavier load ability increased more. In addition, to avoid the limited of the retainer’s material, this bearing is same as the full ceramic bearing of ceramic cage has corrosion resistance and high temperature application. This series of bearing is not for high –speed choice, it should be to install on the unforced side.
