Ca/MB/Cc/Ek/K/ W33 Chrome Steel Spherical Rolling Roller Bearings with C0/C3/P0/P6/P5/P2 roller bearing
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.[1]Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a profile that makes them appear like cylinders that have been slightly over-inflated.
Spherical roller bearings consist of an inner ring with two raceways inclined at an angle to the bearing axis, an outer ring with a common spherical raceway, spherical rollers, cages and, in certain designs, also internal guide rings or center rings. The bearings can also be sealed.

Deep groove ball bearing generally consists a pair of rings, a set of cage, a set of steel balls. Its simple structure and easy usability make itself as the most common and most widely used type of bearings. This kind of bearings is mainly used to bear radial load, moreover, it also could withstand a certain amount of axial load. When increasing the radial clearance of bearing, this kind of bearing has properties of angle contact ball bearing to bear a large axial load within a certain range. After assembled on shaft, the deep groove ball bearing can make the axial displacement limit of the shaft or shell within the bearing′s axial range. Meanwhile, when the shell hole and shaft (or IR to OR) are relatively tilted (within 8 ′- 16′, according to clearance), the bearing could still work as normal, but the service life is reduced.
