  Brief History of Bearing Development

  The bearing is the support of the mechanical drive shaft and is an important guarantee for the performance, function and efficiency of the main engine. It is known as the "joint" of the machine. Its main function is to transmit force and movement and reduce friction loss. Don't think that such high-end devices are modern products. No, bearings have existed on the earth for 8,000 years. Bearings appear for...

  Matching and Pretightening Technology of Angular Contact Bearings

  Under normal circumstances, the group of supporting contact ball bearing contact Angle is the same,When the axial load exceeds the rated requirement, some bearings will be unloaded, which will cause the ball to slip and cause early bearing failure. In order to avoid the unloading phenomenon (i.e., to improve the unloading force), the pre-load of the bearing group can be increased or the bearings with different contact ...

  Features Of WSBC Deep Groove Ball Bearings

  Deep groove ball bearings have a simple structure and are easier to achieve higher manufacturing accuracy than other types. Therefore, they are easy to produce in series and have lower manufacturing costs, and they are extremely common. When a larger radial clearance is selected, the axial bearing capacity increases, and the contact angle is zero when bearing pure radial force. When there is an axial force, the contact ang...
