氮化硅全陶瓷轴承具有氧化锆的所有特性外，还具有自身比重轻，耐磨性好，
硬度高并比氧化锆更耐高温等特点。同时具有良好的高温强度，机枪的抗氧化
能力，高温承载力和良好的耐碱腐蚀性。Silicon nitride ceramic
bearings have all the features of the zirconia, it also
has its own light weight, wear resistance, high
hardness and high temperature more than zirconia
characteristics. Also has good high temperature
strength, the antioxidant capacity of the machine guns,
high temperature bearing capacity and good alkali
corrosion.
