Type of angular contact ball bearings

Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) of several types. This kind of bearing locking in the outer ring, inner and outer rings can not be separated, can be combined radial and axial loads and axial loads in one direction. Axial load capacity determined by the contact angle, the contact angle is larger, the ability to withstand high axial loads. This kind of bearing shaft or housing to limit axial displacement in one direction. Contact ball bearing high speed limit, you can support radial load and axial load can also be subject to pure axial load, axial load capacity determined by the contact angle, and with the contact angle increases.
Single row angular contact ball bearings
Single row angular contact ball bearing can withstand axial load in one direction, the radial load, will cause additional axial force must be applied to the corresponding reverse load, therefore, the types of bearings are generally used in pairs. Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, it can limit the bi-axial displacement of shaft or housing, the contact angle of 30 degrees.
Angular contact ball bearings installed in pairs
Installed in pairs of angular contact ball bearings can bear radial load mainly radial and axial joint load can also be subject to pure radial loads. Tandem configuration can only bear axial load in one direction, the other two configurations can withstand axial load in either direction. This type of bearings are generally manufacturers matching pairs of user submitted after installation preload interference, rings and balls in the axial pre-load condition, thereby enhancing the entire group as a single bearing support stiffness and rotation Accuracy
