Spherical Roller Bearings 21300 Series are double row self-aligning bearings capable of carrying heavy radial loads combined with light-moderate thrust loads in either direction. Precision Roller Bearings 21300 Series are extremely resistant to heavy impact loads and the self-aligning feature allows full capacity loading despite shaft bending and alignment errors of the shaft relative to the housing.
Roller Bearings 21300 Series retainers generally come in pressed steel, solid brass. Annular groove and lubrication holes can also be provided on the center of outer ring.
Spherical Roller Bearings 21300 Series are mainly used in paper-making equipment, metal-making equipment, continuous casters, shaker screens, gears, drives and speed reducers, mining equipment, oil field equipment and other heavy industrial machineries.
Spherical Roller Bearings are commonly used in agricultural machines such as combined harvesting machine, air-blower, paper-machine, textile machine, woodworking machinery, overhead crane moving wheel and driving shaft as well as a large number of non agricultural applications.
