What role does the bearing have？

About Angular Contact Ball Bearing1. There is a contact angle between the ring and the ball, and the standard contact angles are 15,30 and 40;2. The larger the contact Angle, the greater the axial load capacity;3. The smaller the contact Angle, the more conducive to high-speed rotation;4. Single-col

四点接触球轴承是一种分离型轴承，也可以说是一套轴承可承受双向轴向载荷的角接触球轴承。其内外圈滚道是桃型的截面，当无载荷或是纯径向载荷作用时，钢球和套圈呈现为四点接触，这也是这个名称的由来;当只有纯轴向载荷作用时，钢球和套圈就成了两点接触，可承受双向的轴向载荷。四点接触球轴承还可以承受力矩载荷，兼有了单列角接触球轴承和双列角接触球轴承的功能。四点接触球轴承只有形成两点接触时才能保证正常的工作。所以一般适用于那些纯轴向载荷或轴向载荷大的合成载荷下呈两点接触的场合,四点接触球轴承极限转速高，也适合于那些高速运转的场合。Four-point contact ball bearing is a kind

The slewing ring is a special bearing that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. Under normal circumstances, the slewing bearing itself is equipped with mounting holes, lubricating oil holes and sealing devices, which can meet t
