Spherical roller bearings raceways in the outer ring of this type of bearing are designed with a spherical surface, with the center coinciding with the spherical roller bearings centerline. The bearings are of an improved design that incorporates modified line contact between the raceways and rollers. This construction allows the spherical roller bearings to have a very heavy radial load. In addition to its excellent radial capacity, these bearings can also accept a relatively large amount of bi-directional axial loading. Spherical roller bearings can also accommodate some angular misalignment, which makes them excellent choices where shaft deflection or housing alignment exists.

Features:
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) The bearings have 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
Used in agricultural machine such as combine harvesting machine, air-blower, paper-machine, textile machine, woodworking machinery, overhead crane moving wheel and driving shaft, etc.
