A spherical bearing is a bearing that permits angular rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry). Typically these bearings support a rotating shaft in the [bore] of the inner ring that must move not only rotationally, but also at an angle.
Feature
A.Low speed, high resistance to impact, vibration
B.Able to self-align
C.Mainly bear big radial load
D.Can bear fair axial load
Application
Metallurgical and mineral machineries, construction machineries, hoisting and conveying machineries, paper machineries, textile machineries, etc.
Spherical roller bearings are divided into: a cylindrical bore, tapered bore.
Tapered bore taper 1:12, respectively, the post code for the K,-aligning roller bearings (153 000 type or 113 000-type) and 1:30 of the post code for the K30 self-aligning roller bearings. This type of bearing shaft with a conical distribution, the inner ring can be adjusted along the axial movement of the bearing radial clearance.
The range of hrt bearing spherical roller bearings comprises eight series. Series: 222(k), 230(k), 223(k), 232(k), 231(k), 240(k), 241(k), 242(k), 213(k)and so on.Typical applications: blowera and fans, elevators, mining equipment, oil field equipement, paper making machine, pumps, shaker screens, and so on.
