Spherical roller bearings are specialized roller bearings designed to accommodate heavy radial and axial loads in applications where misalignment or shaft deflections are common. These bearings feature two rows of barrel-shaped rollers, which are arranged symmetrically on the inner ring raceway and the outer ring raceway. This unique design allows the rollers to self-align, enabling the bearing to accommodate misalignment or shaft deflections, which makes them ideal for applications where shafts may not be perfectly aligned. Spherical roller bearings are commonly used in heavy-duty industrial machinery, such as mining equipment, construction machinery, paper mills, and steel mills, where they provide reliable performance under demanding operating conditions.
