宁波奔轮轴承有限公司是精密轴承的专业生产企业。主要生产内孔为5mm至25mm的单列深沟球轴承。产品精度等级为P0,P6 级；质量等级为ZV4,ZV3组 无异音。产品广泛应用于电机，电动工具等中小型动力传动装置。 同时，我公司设计并生产非标轴承，为客户提供最佳商业和技术上的解决方案。微型、小型深沟球轴承626VV,626ZZ,607VV,607VV,608ZZ,608VV,6900VV,6900ZZ,
宁波奔轮轴承有限公司研制生产的混合陶瓷球轴承内外圈材料为轴承钢（Gcr15) 陶瓷球主要有氮化硅（Si3N4）、氧化锆（ZrO2）、氧化铝（Al2O3）等。
Si3N4 陶瓷的密度为3.20g/cm3,比轴承钢7.85g/cm3的密度要低许多。因此陶瓷滚动体能有效抑制高速转动产生的离心力，降低滚动体载荷，极大拓展了滚动轴承的应用领域。同时可以减少滚动体与滚道面之间的旋转滑动，可显著提高轴承接触疲劳寿命。因此，混合陶瓷球轴承可用于需要高速运转的领域，例如高速电主轴轴承、机床主轴轴承、牙钻轴承、高速磨头轴承、仪表用轴承、硬盘驱动器轴承等。还能够应用于如旱冰鞋、航模和电动玩具等民用产品

Single row deep groove ball bearings:
Bearing bore: 5mm-25mm;
Precision grade: P0, P6;
Quality grade: ZV4, ZV3;
EMQ quality;
Application: Electric machines, electric tools.
Non-standard bearings
Mini/Small deep groove ball bearings 626VV, 626ZZ, 607VV, 607VV, 608ZZ, 608VV, 6900VV, 6900ZZ
The hybrid ceramic ball bearing developed by Ningbo Benlun Bearing Co., Ltd. features bearing rings made of bearing steel (Gcr15). The ceramic ball is mainly made of Si3N4, ZrO2, Al2O3, etc.
The density of Si3N4 ceramic is 3.20g/cm3, much lower than that of bearing steel (7.85g/cm3). For this reason, the ceramic rolling element can effectively restrain the centrifugal force generated by high-speed rotation and reduce the load of rolling element, greatly expanding the application of rolling bearings. Meanwhile, it can also reduce the rotational slide between the rolling element and the raceway surface and thus can significantly extend bearing contact fatigue life. Therefore, ceramic ball bearing can be used in high-speed rotation application, such as high-speed motor spindle bearing, machine spindle bearing, dental drill bearing, high-speed wheel head bearing, instrument bearing and hard drive bearing. It can also be used in civilian products like roller skate, aero-modeling and electric toy.
