Product Description
The outer spherical ball bearing with a seat is composed of an outer spherical ball bearing with seals on both sides and a cast (or steel plate stamped) bearing seat. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of this type of bearing is wider than the outer ring The outer ring has a truncated spherical outer surface, which can automatically align with the concave spherical surface of the bearing seat. Usually, there is a gap between the inner hole of this type of bearing and the shaft. The inner ring of the bearing is fixed to the shaft with a top screw, eccentric sleeve or clamping sleeve, and rotates together with the shaft
Pillow block bearing
It is mainly used to bear radial and axial combined loads, mainly radial loads. Generally, it is not suitable to bear axial loads alone. This type of bearing can be separately installed with an inner ring (with a full set of rollers and retainers) and an outer ring. This type of bearing does not allow the shaft to tilt relative to the housing, as it 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 relatively high; 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 bearing during installation and operation. If necessary, pre interference installation can be used to increase the rigidity of the bearing.
A spherical bearing with a seat is a type of bearing unit that combines a rolling bearing with a bearing seat. Most outer spherical bearings have a spherical outer diameter and are installed together with imported bearing seats with spherical inner holes. They have various structural forms, good universality and interchangeability.
