Advantages of ceramic bearings produced by Shanghai Yuwei Bearing:  
、陶瓷几乎不怕腐蚀,所以,适宜于在布满腐蚀性介质的恶劣条件下作业。 1. Ceramics are scarcely afraid of corrosion, so it is suitable for operation in harsh conditions covered with corrosive media.  
、陶瓷滚动球的密度比钢低,重量更要轻得多,因此转动时对外圈的离心作用可降低 40% ,进而使用寿命大大延长。 2. The density of ceramic rolling balls is lower than that of steel, and the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating , and the service life is greatly extended.  
、陶瓷受热胀冷缩的影响比钢小,因而在轴承的间隙一定时,可允许轴承在温差变化较为剧烈的环境中工作。 3. Ceramics are less affected by thermal expansion and contraction than steel, so when the bearing clearance is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.  
、陶瓷的弹性模量比钢高,受力时不易变形,因此有利于提高工作速度,并达到较高的精度。 4. The elastic modulus of ceramic is higher than that of steel, and it is not easy to deform when subjected to force, so it is conducive to improving the working speed and achieving higher accuracy.  
、无油自润滑 , 防磁电绝缘 , 可用于超真空环境中 , 不锈特性 , 可用于任何潮湿环境或水中 . 5.Oil- free self-lubricating , anti-magnetic electrical insulation , can be used in ultra-vacuum environment , stainless characteristics , can be used in any humid environment or water .  
、陶瓷材料本身具有耐高温的特性 , 所以陶瓷轴承可用于高温的工作环境中 . 6 , ceramic material itself has high temperature resistance characteristics , so ceramic bearings can be used in high temperature working environments .  
Disadvantages of ceramic bearings:  
、因材料本身的特性 , 故加工难度大 . 1.Due to the characteristics of the material , processing is difficult .  
、成本高 . 2.High cost .  
、硬度高 , 但韧性较差 , 不耐受冲击 . 3 , high hardness , but poor toughness , not resistant to impact .  
、密封性能较差 , 不太适合在粉尘太多的环境下工作 . 4.The sealing performance is poor , and it is not suitable for working in an environment with too much dust .  


Product Usage:  
Plating equipment, cleaning machinery, medical equipment, low temperature engineering, optical instruments, high speed machine tools, high speed motors, printing machinery, food processing machinery.  

First, the installation of ceramic bearings:  
、安装轴承时,务须在套圈端面的圆周上施加均等的压力,为将套圈装入,严禁用榔头等重器直接敲击轴承端面,以免损伤轴承 ! 1. When installing the bearing, it is necessary to apply equal pressure on the circumference of the end face of the ferrule. In order to install the ferrule, it is strictly forbidden to directly hit the end face of the bearing with a hammer or other weight to avoid damage to the bearing !  
、此外,如果对套圈的某一方 ( 例如外圈 ) 施加压力,而通过滚动体将套圈的另一方 ( 例如内圈 ) 压入,这往往要在滚动面上造成压痕或擦伤,万不可采用。 2. In addition, if pressure is applied to one side of the ferrule ( such as the outer ring ) and the other side of the ferrule ( such as the inner ring ) is pressed in by a rolling body , this often results in indentations or abrasions on the rolling surface. It must not be used. , 需用垫铁将内外圈均衡地压入。 Especially when the non-separable bearing is installed on the shaft and the bearing seat at the same time , the inner and outer rings need to be pressed in evenly with a horn.
Matching of ceramic bearings  
、过盈量 1.Interference  
The inner ring and the outer ring of the rolling bearing are fixed on the shaft or the bearing seat, so that when the bearing bears the load, the radial, axial and rotational directions of the mating surface of the ring and the shaft or the bearing box will not undergo relative movement. This relative movement will cause wear, friction corrosion, or friction cracks on the mating surface, resulting in damage to the bearings, shafts, and bearing housings, and then the wear powder will mix into the bearings, which will cause poor operation, abnormal heating, or vibration.  
、关于固定轴承的方式 2. Ways to fix bearings

The interference fit is best left on the mating surface of the ferrule with the shaft or bearing housing, and the static fit is best. This cooperation can make the load of the thin-walled ferrule evenly distributed on the circumference, without affecting the load capacity of the bearing. However, when the static fit is used, except for the inconvenience of installing and removing the bearing, the free-side bearing cannot be moved axially when the release bearing is used, so it cannot be used in all occasions.
