Spherical roller bearings are designed to accommodate heavy radial and axial loads, making them suitable for applications with high load demands such as mining, construction, and heavy machinery. These bearings have a spherical outer ring raceway and a double row of barrel-shaped rollers, allowing them to accommodate misalignment between the shaft and housing. This self-aligning capability helps to compensate for shaft deflection or misalignment, reducing stress on the bearing and prolonging its service life.
