High Speed Fast Delivery Axial Spherical Roller Bearings 21305 21306 CC CCK

Description,

1. Spherical roller bearings are equipped with drum roller bearings between an inner ring with two raceways and a spherical outer ring. The center of curvature of the outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and the shell are deflected, the load can be adjusted automatically and the axial load in two directions can be adjusted. Large radial load capacity, suitable for heavy load and impact load. The inner diameter of the inner ring is a bearing with a tapered bore, which can be directly installed. Or use an adapter sleeve and a disassembly cylinder for installation on a cylindrical shaft. The cage is made of a steel sheet pressed cage, a polyamide formed cage, and a copper alloy car cage.

2. For self-aligning bearings, when the bearing with shaft is installed in the shaft hole of the box body, the use of an intermediate mounting ring can prevent the outer ring from tilting and rotating. It should be remembered that the balls of some sizes of self-aligning ball bearings protrude from the side of the bearing, so the middle mounting ring should be recessed to prevent damage to the balls. A large number of bearings are generally installed by mechanical or hydraulic press-in methods.

SKF sealed spherical roller bearings, Specification,

Self-aligning roller bearings, Application,

Spherical roller bearing Since the arc center of the outer ring raceway is consistent with the bearing center, it has self-aligning performance, so it can automatically adjust the axis misalignment caused by the deflection or misalignment of the shaft or housing. Can withstand radial and bidirectional axial loads. Especially large radial load capacity, suitable for bearing heavy and shock loads Main applications: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox seats, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings
