Spherical Roller Bearings

Self aligning roller bearings have double row rollers, with one shared spherical raceway on the outer ring and two raceways on the inner ring that are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have automatic centering performance, which is not susceptible to the influence of the angle between the shaft and the bearing housing seat on errors or shaft bending. It is suitable for situations where installation errors or shaft deflection cause angular errors. This bearing can not only withstand radial loads, but also axial loads acting in both directions. There are two types of inner holes for self-aligning roller bearings: cylindrical and conical. The taper of the conical hole is 1:30 and 1:12. This type of conical inner hole bearing is equipped with a locking sleeve or a detachable sleeve, which can easily and quickly assemble the conical inner hole self-aligning ball bearing on the optical shaft or stepped machine shaft. Self aligning roller bearings are mainly used in paper making machinery, reduction devices, railway vehicle axles, steel rolling machine gearbox bearing seats, steel rolling machine rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, and vertical belt seat self aligning bearings.
