   陶瓷轴承作为一种重要的机械基础件, 由于他们具有金属材料的轴承无法企及的优良性能,抗高温,超强度等特点。 As a kind of important mechanical basic parts, Yuwei ceramic bearings have excellent performance, high temperature resistance, super strength and other characteristics that cannot be achieved by bearings made of metal materials. 在国民生产领域受到越来越多的重视: In the past ten years, more and more attention has been paid in the field of national production:

用途 判定: Judging according to the use of ceramic bearings :

可应用在炉窑,制塑、制钢等高温设备中 -因为膨胀系数小。 First, it can be used in high temperature equipment such as furnaces, plastics, and steel -because the expansion coefficient is small.

可应用在强酸、强碱、无机、有机盐、海水等领域,如:电镀设备,电子设备,化工机械、船舶制造、医疗器械 等领域- 材料本身 耐腐蚀的特性 Second, it can be applied in the fields of strong acid, alkali, inorganic, organic salt, seawater, etc., such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment and other fields-the material itself is resistant to corrosion .

可用在退磁设备。 Third, it can be used in demagnetization equipment. - 因无磁不吸粉尘,可减少轴承提前剥落、噪声大等 Precision equipment and other fields - Because it is non-magnetic and does not attract dust, it can reduce the bearing's premature peeling and high noise .

可用在各种要求绝缘的电力设备中 - 因电阻力高,可免电弧损伤轴承 Fifth, it can be used in a variety of electrical equipment that requires insulation - due to the high resistance, it can avoid arc damage to the bearing .

因陶瓷材料独具的无油自润滑特性,在超高真空环境中,可克服普通轴承无法实现润滑之难题。 Sixth, due to the unique oil-free self-lubricating characteristics of ceramic materials, in the ultra-high vacuum environment, it can overcome the problem that ordinary bearings cannot achieve lubrication.

御微轴承

According to the material of ceramic bearings:

氧化锆:全陶瓷轴承具抗磁电绝缘、耐磨耐腐蚀、无油自润滑、耐高温耐高寒等特点, 可用于极度恶劣环境及特殊工况。 First, zirconia: all-ceramic bearings have the characteristics of anti-magnetic and electrical insulation, wear resistance and corrosion resistance, oil-free self-lubrication, high temperature and high temperature resistance, and can be used in extremely harsh environments and special conditions. Ferrules and rolling elements are made of zirconia (ZrO2) ceramic material, and the holder uses polytetrafluoroethylene (PTFE) as a standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25) and special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

氮化硅:氮化硅全陶瓷轴承套圈及滚动体采用氮化硅(Si3N4)陶瓷材料,一般也可使用RPA66-25,PEEK,PI,以及酚醛夹布胶木管等。 Second, silicon nitride: silicon nitride all-ceramic bearing rings and rolling elements are made of silicon nitride (Si3N4) ceramic materials. Generally, RPA66-25, PEEK, PI, and phenolic laminated bakelite pipes can also be used. Compared with ZrO2 materials, all ceramic bearings made of SiN4 are suitable for higher speed and load capacity, as well as higher ambient temperature. At the same time, we can provide precision ceramic bearings for high-speed, high-precision and high-rigidity spindles, with the highest manufacturing accuracy of P4 to UP.

满装球:满装球型全陶瓷轴承一面带添球缺口,因采用无保持架结构设计,可以比标准结构的轴承装入多的陶瓷球,从而提高其负荷能力,另外还可避免因保持架材料的限制,可达到陶瓷保持架型全陶瓷轴承耐腐蚀及耐温效果。 Third, full-loaded balls: Full-ball full-ceramic bearings have ball gaps on one side. Because of the cageless design, more ceramic balls can be installed than bearings with standard structures, thereby increasing their load capacity. To avoid the limitation of the cage material, the ceramic cage type full ceramic bearing can achieve the corrosion resistance and temperature resistance. This series of bearings is not suitable for higher speeds. When installing, pay attention to install the notched surface on the end that does not bear axial load.

混合:陶瓷球特别是氮化硅球具有低密度、高硬度、低摩擦系数,耐磨、自润滑及刚性好等特点,特别适合做高速、高精度及长寿命混合陶瓷球轴承的滚动体(内外圈为金属)。 Fourth, hybrid: Ceramic balls, especially silicon nitride balls, have the characteristics of low density, high hardness, low friction coefficient, wear resistance, self-lubrication and good rigidity. They are particularly suitable for high-speed, high-precision and long-life hybrid ceramic ball bearings. Rolling elements (inner and outer rings are made of metal). Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (AISI440C). Ceramic balls can be made of ZrO2, Si3N4, or SiC.
