Excellent thermo mechanical properties have seen this material used for engine parts, bearings, metal machining and other industrial applications. Reliability is the most important criteria in aerospace applications. Standard Diameter: 3/32" / .09375 Inches Metric Diameter: 2.38125mm Grade: 5 Material: Si3N4 Silicon Nitride Ball Weight (each): .00081863 Ounces / 0.0232 Grams Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temperatures are facto Alibaba.com offers 3,629 silicon nitride bearings products. News. Therefore, ball bearings made of silicon nitride ceramic are used in performance bearings. Silicon nitride is a man made compound synthesized through several different chemical reaction methods. A wide variety of silicon nitride bearings options are available to you, such as material, structure, and applicable industries. Size: 1.5mm (0.0591") 2. Hot-pressed silicon nitride was evaluated as a rolling-element bearing material. Silicon nitride bearings. Color: Black. Our Ceramic Silicon Nitride Balls were harder and 79% lighter than tungsten carbide which lowered rotational mass, increased speed, decreased heat and friction, and lasted much longer. The wear resistance, low friction, and high stiffness of silicon nitride improves the performance of high temperature bearings. Discover the latest news from our world of advanced ceramics and find out at which trade fairs, events or congresses you can meet or see our specialists again in the coming months. a great option for many high-tech and high-performance industries. For a given applied load, the contact (Hertz) stress in a hybrid bearing will be higher than that of an all-steel rolling element bearing. It … They are also lightweight with less than half the density of steel balls, helping to conserve energy. Silicon nitride is also used as a dielectric material for microelectronic or photonic applications. Silicon nitride is often used as a passivation layer for integrated circuits or micro mechanical structures.
