With the progress and development of science and technology, the application of machinery and equipment is more and more extensive, in machinery and equipment bearings have a very important role, it is the core of the operation of machinery and equipment.

Spherical Roller Bearing is a kind of bearing, it has two rows of rollers, mainly bear the diameter of a load, but also can bear the axial load in either direction. There are high radial load capacity, especially suitable for heavy load or vibration load work, but can not bear pure axial load. This kind of bearing outer ring raceway is spherical, so its alignment performance is good, can compensate for coaxiality error.

A. Characteristics of Spherical Roller Bearing

1.Spherical Roller Bearing has double rows of rollers, outer ring has 1 common spherical raceway, inner ring has 2 raceways and tilted into an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easy to be affected by the shaft and bearing box angle error or shaft bending, suitable for installation error or shaft deflection and angle error caused by the occasion. The bearing can bear radial load, but also can bear the two-way role of the axial load.

2. outer ring raceway surface for the spherical surface, with alignment performance. Due to processing and installation and shaft bending caused by the shaft and seat hole different heart when suitable for this bearing. Adjustment of the skew angle can be within 3 °.

3. Bearing contact angle is small, almost unchanged under the action of axial force, axial bearing capacity is small. Mainly bear radial load, in bearing radial load at the same time, can also bear a small amount of axial load, the limit speed than deep groove ball bearing low.

4. outer ring raceway is a spherical part, the bearing has internal alignment performance to adapt to the relative deflection of the shaft and seat hole. Can bear radial heavy load and shock load, also can bear certain bidirectional axial load. This type of bearing can limit the axial displacement of the shaft or shell in the axial clearance range of the bearing.

Second, Spherical Roller Bearing main use

Spherical Roller Bearing can be used in paper making machinery, speed reducing device, railroad vehicle axle, rolling mill gear box bearing housing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial speed reducer, vertical spherical roller bearing with seat.
