The angular touch ball bearing has a higher limit speed; it can accept radial load and axial load together; it can also accept pure axial load; its axial load can be determined by the touch angle; and it increases with the increase of the touch angle.
Single-row angular touch ball bearings can only accept axial loads in one direction; when receiving radial loads; cause additional axial forces; it is necessary to apply corresponding reverse loads; therefore; such bearings are usually used in pairs. Double row angular contact ball bearings can accept large radial and axial bidirectional combined loads and moment loads with radial loads; it can constrain the axial displacement of the shaft or casing; the contact angle is 30 degrees.
Paired device angular touch ball bearings can accept radial and axial bidirectional combined loads with radial loads; they can also accept pure radial loads. Series devices can only accept axial loads in a single direction; the other two devices Accept axial load in either direction.
Bearings of this type are usually selected by the manufacturer in pairs and submitted to the user; the device is preloaded and overfilled; the ferrule and the steel ball are in an axial preload condition; thus the entire set of bearings is increased as a single support stiffness and rotation Precision.
