    The Characteristics of Thrust Ball Bearing

    In general,thrust ball bearings has the following characteristics: 1.Thrust ball bearing is separable bearing, the conact angle is 90 °, it can be installed separately , and can only endure axial load. 2.Thrust ball bearing has low limit speed. The steel ball and centrifugal force push the outside of the bearing race , it’s easy to scratch, and not suitable for high-speed operation. 3.The unilateral bearing and on...

    Purposes of Roller Bearing Lubrication

    The main purposes of lubrication are to reduce friction and wear inside the bearings that may cause premature failure . The effects of lubrication may be briefly explained as follows : 1.Reduction of friction and wear Direc metallic contact between the bearing rings , rolling elements and cage,which are the basic components of a bearing , is prevented by an oil film which reduces the friction and wear in the contact areas ...

    What is Thrust Ball Bearing?

    Thrust ball bearings are designed to bear thrust loads at high speeds. They are made of washers with raceway the thrust ball bearing is divided into two types: flat seat cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but can not bear radial load. So how much do you know about the performance characteristics and advantages of thrust ball bearings?Wuxi S...

    The Brief Introduction of Angular Contact Ball Bearing

    Angular contact ball bearing, there is angular between bearing race and balls, the standard contact angle is 15°, 30°and 40°. The larger the contact Angle, the greater the axial load capacity. The smaller the contact Angle, the more conducive to high-speed rotation. Single row angular contact ball bearing can endure radial load and unidirectional axial load.DB, DF assembly and double row angular contact ball bearing ca...
