Slewing bearing is a kind of large bearing which can bear comprehensive load, and can bear large axial and radial load and overturning moment at the same time. Slewing bearing is generally equipped with mounting holes, inner or outer gears, lubricating oil holes and sealing devices, which can make t

Tip 1, the use of copper rod and manual hammer installationThis is a simple way to install small and medium-sized bearings. When the inner ring of the bearing is a tight fit and the outer ring is a loose fit, the copper rod is pressed close to the end face of the inner ring of the bearing, and the c

In the long-term production status monitoring, we found that the double-column angle contact ball bearing showed strong regularity during its use, and had very good repeatability. When the normal high-quality bearings are used, the vibration and noise are relatively small, but the spectrum is scatte

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
