Spherical roller bearings have double row rollers, with one shared spherical raceway on the outer ring and two raceways on the inner ring tilted at an angle relative to the bearing axis. This clever construction gives it automatic centering performance. Main applications: Paper making machinery, reduction gear, railway vehicle axles, bearing seats for rolling mill gearboxes, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical seat self-aligning bearings.
