Spherical roller bearings consist of a double row with solid outer rings and a concave raceway, solid inner rings, and barrel rollers with cages. They are constructed for industrial applications and can support large loads. Many models self-align, and are able to tolerate the smallest instances of misalignment. Because these bearings have a high degree of shock tolerance, they are able to withstand significant vibrations.
Some applications include high levels of pollution because spherical bearings perform well in those environments. Spherical roller bearings can be manufactured with chrome, steel, or brass, with either a straight or tapered bore. The best uses for a spherical roller bearing require maximum load capacities.
