JYC four-point contact ball bearing

The angular contact ball bearing is divided into angular contact ball bearing,doule row angular confact ball bearing and four point contant ball bearing .It can bear radial and axial roads at the same time and can bear pure axial load as well with higher limiting speeds .The capability of bearing axial load is determined by the degree of contact angle,The bigger the contact angleis ,the bigger the axial load can be borne. The contact angles are classified as 15º?25º?40º.When the bearing bears radial load, additional axial force will mountage in pairs, there are three knids of mountages, namely ,back to back ,face to face and in series. When the contact angle for the double row angular contact ball bearing is 30º,it can bear bigger radia and axial bidirectional combined loads and moment load with radial load in the main. The bearing is mainly used in the units for restriction of bidirectional axial displacement of shaft or housing .Double row angular contact ball bearing are divided into two structures-one outer ring with two inner rings and two outer rings with one inner ring. ???????????????
