    Product Description
    Product Description

    Angular contact ball bearings remove one shoulder, resulting in a higher load-bearing capacity of the ball, allowing it to withstand higher loads and speeds.

    Single row angular contact ball bearings bear thrust loads in one direction and are commonly used in machine tool spindles. At high speeds, these bearings can withstand both high radial and unidirectional axial forces simultaneously.

    Application Area

    Although its basic performance should be similar to that of deep groove ball bearings, due to the fact that this type of bearing is mostly used in relatively rough machinery, the installation and positioning are not precise enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and has large deflection, and the accuracy of the bearing itself is not high enough. Some structures are also relatively rough, so the actual performance of deep groove ball bearings with the same specifications should be given a considerable discount.

    The performance of the outer spherical ball bearing with eccentric sleeve is basically the same as that of the outer spherical bearing with top screw, except that the top screw is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole outer spherical ball bearing is a tapered hole with a 1:12 taper, which can be directly installed on the tapered shaft or installed on the shoulder less optical shaft with the help of a locking sleeve, and the bearing clearance can be fine tuned.

    Advantages And Characteristics

    Self aligning roller bearings are divided into two different structures based on the cross-sectional shape of the rollers: symmetrical spherical rollers and asymmetric spherical rollers. Asymmetric self aligning roller bearings are early products mainly used for host maintenance services. When designing new hosts, symmetrical self aligning roller bearings are rarely used. The internal structure has been comprehensively improved and optimized, and compared with early produced self aligning roller bearings, they can withstand greater axial loads, The operating temperature of this type of bearing is relatively low, so it can adapt to the requirements of higher speeds. It can be divided into two types based on the presence or absence of retaining edges on the inner ring and the different types of cages used. The characteristics of C-type bearings are the absence of retaining edges on the inner ring and the use of steel plate stamped cages. The characteristics of CA type Treen bearings are the presence of retaining edges on both sides of the inner ring and the use of vehicle made solid cages.

    Usage Guide

    External spherical bearings are preferred for applications that require simple equipment and components, such as in agricultural machinery, transportation systems, or construction machinery. Mainly used to withstand combined radial and axial loads mainly based on radial loads, it is generally not suitable to bear axial loads alone. This type of bearing can be installed with inner and outer rings separately. This type of bearing does not allow the shaft to tilt relative to the casing, and will generate additional axial force under radial load. The size of the axial clearance of this type of bearing is closely related to its normal operation. When the axial clearance is too small, the temperature rise is higher; When the axial clearance is large, the bearing is prone to damage. Therefore, special attention should be paid to adjusting the axial clearance of the bearings during installation and operation. If necessary, pre interference installation can be used to increase the rigidity of the bearings.
