30314 Tapered roller bearings

30314 Tapered roller bearings The outer ring (or inner ring) of a double-row tapered roller bearing is a whole, and the small end faces of the two inner rings (or outer rings) are similar, and there are spacer rings in the middle. The bearing can bear two-way axial load while bearing radial load, and can limit the two-way axial movement of the shaft or housing within the axial clearance range of the bearing. The performance of this kind of bearing is basically the same as that of double-row tapered roller bearings, but the radial load is larger than that of double-row tapered roller bearings, and the limit speed is slightly lower, which is mainly used for heavy machinery, such as rolling mills.
