How do spherical roller bearings work ?


Spherical roller bearing has two columns symmetric spherical roller type, there is a share of the spherical raceway outer ring, inner ring has two the tilt Angle of a race to the bearing axis, has a good heart performance, when the axial stress bending or install different heart bearings can still be used normally, so vary with different bearing size series, generally allowed by the self-aligning Angle for 1-2.5 degrees, The load capacity of this type of bearing is large. In addition to the radial load, the bearing can also bear the axial load of two-way action, and it has good impact resistance. Generally speaking, the working speed allowed by self-aligning roller bearings is low.


Basic working mechanism of self-aligning roller bearing


The inner ring of the rolling bearing is used for assembly with the journal, and the outer ring is used for assembly with the bearing. Usually the inner ring rotates with the journal, and the outer ring is fixed, but it can also make the outer ring rotate while the inner ring does not move, or the inner and outer rings rotate simultaneously. When the inner and outer rings rotate relative, the rolling body is rolling between the inner and outer rings. WSBC 23152 CCK/W33 bearings online , pls click here :

Most commonly used single row rolling bearings. According to the number of rolling body columns, bearings can also be divided into double and multiple columns of bearings, and two or several columns of rolling bodies are installed in the same bearing. A number of rolling bodies are installed between the bearing ring or the shaft and the seat ring. The rolling bodies are evenly spaced by the cage, and the cage prevents the rolling bodies from colliding with each other, so as to reduce the resistance so that the bearing can reach a higher speed. 


The classification of bearings is mainly based on the shape of the rolling body, the bearing force and the structural form. The structure of the rolling bearing is generally composed of the inner ring, the outer ring, the rolling body and the cage.


Rolling bearings have a variety of structures. However, the most basic structure is composed of an inner ring, an outer ring, a rolling body and a cage. The rolling body (ball, roller or needle roller) is usually arranged evenly between the two rings in the bearing with the help of the cage. Its shape, size, and number directly affect the load capacity and performance of the bearing. WSBC 23224 CC/W33 bearings online , pls click here :

For centripetal bearings, the inner ring is usually closely matched with the shaft and runs together with the shaft. The outer ring is usually overmatched with the bearing seat or mechanical housing and plays a supporting role. However, in some cases, there is also an outer ring running, the inner ring is fixed for support or the inner ring and the outer ring are all running at the same time.


Widely application of  spherical roller bearings


Spherical roller bearings were first used for heavy-duty, medium-speed and mission-risk applications, and later their applications were extended to wind turbines, Marine propulsion, sugar processing, pulp and paper, material handling, mining and construction machinery, etc. Spherical roller bearings allow for low friction rotation and can cope with angular eccentricity, a factor driving their continued penetration into a wider range of applications.
