Spherical roller bearings are bearings with drum rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways. Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. With high radial load capacity, it is especially suitable for work under heavy load or vibration load, but can not bear pure axial load. The raceway of the outer ring of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate the coaxiality error.   Internal Structure and Retainer Material Variation C: Symmetrical roller, Stamped Steel retainer Spherical Roller Bearing CA: Symmetrical roller, one-pice brass cage Spherical Roller Bearing CTN1: Symmetrical roller, nylon cage Spherical Roller Bearing E: Third generation design. improved stress distribution; offer much longer service life than normal designs Spherical Roller Bearing Q: Bronze cage Spherical Roller Bearing MB: Symmetrical roller,Two-pice brass cage Spherical Roller Bearing EM: Symmetrical roller, Special alloy Integral cage.Spherical Roller Bearing
