Product Description
Outer spherical ball bearings are actually a variant of deep groove ball bearings, characterized by a spherical outer diameter surface on its outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat for centering. Outer spherical bearings are mainly used to withstand combined radial and axial loads, mainly radial loads, and are generally not suitable for bearing axial loads alone. The outer spherical surface can be divided into seated outer spherical bearings, top threaded outer spherical bearings, tapered outer spherical bearings, and eccentric sleeve outer spherical bearings.
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.
Application area
Outer spherical bearing is a commonly used type of rolling bearing, characterized by a spherical outer diameter surface on the outer ring, suitable for bearings in industrial machinery, mining and metallurgy, agricultural machinery, transportation systems, construction machinery, and other fields.
