Details:
Spherical Roller Bearing
 
These bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical
raceway. Since the center of curvature of the outer ring raceway surface coincides with the bearing axis, they are self-aligning in a manner
similar to that of self-aligning ball bearings. Therefore, if there is deflection of the shaft or housing or misalignment of their axes, it is
automatically corrected so excessive force is not applied to the bearings.
 
Features  of Self-aligning Roller Bearing 
1) Spherical roller bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in out
ring, the two inner ring raceways are included at an angle to the bearing axial
2)With good self-aligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft
Misaligning in mounting, and their permissible aligning angle is 1 to 2.5 degree
3) This type of bearings has heavy load carrying capacity and anti-impact ability, in addition to radial loads, they also can carry axial loads
in two directions
4)In general, this type of bearings permits a low limiting speed.
 
Applications of Spherical Roller Bearing
Injection molding machines, crane hooks, vertical pumps .It is mainly applied in hydroelectric generator, vertical motors, propeller shafts for
ships, jib cranes, rolling mail roll necks
 
 
Quality Control
We make all the beating according to the quality standard of ISO9001:2008 and ASME. We have our own in-house lab to test the material
and bearing. Our strict testing and inspection system guarantee the high hardness, high abrasion and high temperature resistance, Before
delivery, there will be a final and extra quality confirmation to ensure all the beatings in good order and condition 
Job requirements 
1.Allow aligning angle is 0.5 °, the operating temperature of -20 °C ~ 110 °C. 
2.Depending on whether the wall and the inner ring with the cage can be divided into type C and type two basic types CA, C-type bearings 
are characterized by inner wall and the use of steel cages, CA bearing characteristics compared to both sides of the inner wall and the use of 
the car solid cage.
