In today's society, angular contact ball bearings are very versatile and require bearings in many fields, while angular contact ball bearings have several different colors than other types of bearings! Generally, the axial load that a single row of angular contact ball bearings can accept is only the load from one direction, and can only limit the axial displacement stress of the bearing shell and the shaft in the same direction. If a pair of bearings are installed, the bearing is made. The outer ring is opposite so that it prevents the occurrence of additional axial forces on the wire cylinder. Angular contact ball bearings are also divided into several types, separate, non-separable, paired angular contact bearings and double row angular contact ball bearings, and these sub-bearings are different. When we use it, we need to understand it from the powder to ensure that the machine can run well after installation.
The rolling element of an angular contact ball bearing is a ball because it is a kind of point contact (distinguished from the line contact of the roller bearing), so it can provide higher rotation speed, smaller heat generation and higher rotation precision. In the case of ultra-high-speed spindle applications, hybrid bearings with ceramic balls are also used. Compared with the traditional steel ball, the ceramic ball material itself gives the ceramic ball bearing a high rigidity, high rotation speed, high temperature resistance and long life, thus meeting the customer's demand for machine tool bearing products.
In terms of the contact angle of angular contact ball bearings, the current popular contact angles of 15 and 25 degrees; usually a contact angle of 15 degrees has a relatively high rotational speed performance, while a contact angle of 25 degrees has a high axial load carrying capacity. Because the preload selection has a great influence on the application of precision angular contact ball bearings, such as high load bearing and high rigidity, medium or heavy bearing preloading is preferred; for high speed and high precision applications, In the early selection of imported bearings, it is necessary to pay attention to the selection of the appropriate preload. The preload is divided into three types: light, medium and heavy. The light preload is more common. In order to facilitate the use of customers, there will be a pair of precision angular contact ball bearings. This type of imported bearings eliminates the customer's preload regulation, which saves installation time.
