A pillow block ball bearing is a bearing unit that combines a rolling bearing with a bearing seat. Most of the outer spherical bearings are made of spherical outer diameter and installed together with imported bearing seats with spherical inner holes. They have various structural forms and good versatility and interchangeability. Can work in harsh environments. Do you know what are the features of this kind of pillow block ball bearing?

Ball bearings with seats are generally cast. At the same time, this type of bearing also has a certain self-alignment in design, easy to install, and has a double-structured sealing device, which can work in harsh environments. The bearing seat is generally cast. Commonly used seats are vertical seat ( P ), square seat ( F ), boss square seat ( FS ), boss circular seat ( FC ), diamond seat ( FL ), ring seat ( C ), slider seat ( T )Wait.

The pillow block ball bearing is actually a variant of the deep groove ball bearing. Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and deflected. In the case of large and other, and the bearing itself is not high enough precision, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a considerable discount.

The pillow block ball bearing is mainly used to bear the combined radial and axial load mainly based on radial load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with inner ring (with a full set of rollers and retainers) and outer ring. The pillow block ball bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load.

The size of the axial clearance of the pillow block ball bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise will be high; when the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.

Compared with other ordinary bearings, a pillow block ball bearing has a double-layer seal, because the operating conditions of the pillow block ball bearing are generally harsh, especially for agricultural machinery bearings, and the double-layer seal ensures that the dust is not easy to enter the inside of the channel. In the past two years, some companies have developed a three-lip seal outer spherical bearing to greatly strengthen the dustproof ability and prolong the service life of the bearing.
