Silicon nitride balls are used in full ceramic and hybrid-ceramic bearings in applications where ultra high-speed rotation is required. The density of silicon nitride is less than half that of steel, reducing the centrifugal force during bearing rotation which enables faster operating speeds.

Why is silicon nitride used in bearings?
Silicon nitride balls are used in full ceramic and hybrid-ceramic bearings in applications where ultra high-speed rotation is required. The density of silicon nitride is less than half that of steel, reducing the centrifugal force during bearing rotation which enables faster operating speeds.
Can you machine silicon nitride?
Silicon Nitride Machining Silicon Nitride can be machined in green, biscuit, or fully dense states. It can be machined relatively easily into complex geometries while in the green or biscuit form.
How are silicon nitride balls made?
Silicon nitride bearing ball is a man-made composite product synthesized through several different chemical reaction methods. Parts are pressed and sintered by well-developed methods to produce a ceramic with a unique set of outstanding properties. Silicon nitride ceramic is ideal for bearing parts.
How are silicon nitride bearings made?
At CBR, all of our ceramic ball bearings use solid silicon nitride balls (Si3N4) made from top-quality powders. They go through a complex hot isostatic pressing (HIP) process, which increases the density of the ceramic balls through the simultaneous application of pressure and heat.
What does 2z mean on a bearing?
2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open.
Is silicon nitride a ceramic?
Silicon nitride (Si3N4) is a covalently bonded crystalline ceramic.
What is the formula of silicon nitride?
Si3N4Silicon nitride / Formula
What are ceramic bearings made of?
Ceramic bearings made from ZrO2, or zirconium dioxide, is a tough ceramic material with very similar expansion properties to steel, although they are 30% lighter.
Can ceramic bearings shatter?
Yes. Full ceramic bearings have load ratings 25 to 35 per cent lower than steel bearings. As the material is much harder, it is also more brittle. Therefore, when put under too much pressure, ceramic material may crack while steel is more likely to suffer indentations.
What is the difference between ZZ and 2z bearings?
2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open. I hope my answer is beneficial for you.
What does LLB mean on a bearing?
LLB = light contact, dual lip, nitrile rubber, steel insert. LLU = full contact, dual lip, nitrile rubber, steel insert.
How does titanium aluminum nitride coating work?
Today we want to look at how this process works and what makes it beneficial for your work. Titanium Aluminum Nitride (TiAIN) is a thin coating that was initially developed by adding aluminum to titanium nitride. The result is a coating for machine tools that is generally superior and more useful in most applications.
What is the best form of silicon titanium nitride?
Silicon Titanium Nitride is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.
What are the applications of titanium silicon nitride coatings?
Applications for titanium silicon nitride coatings appear centered mainly in the defense and aerospace industries. Many potential applications would exist for an industrial coating capable of offering both increased hardness and increased heat and corrosion resistance properties.
What is silicon nitriding?
The use of silicon nitriding as a surface treatment assists manufacturers in creating harder, more durable ceramic coated products. It consists of a compound formed between the elements silicon, which is used widely in computer chip manufacturing, and nitrogen. Some forms of this compound have greater stability than others.
