31318Tapered roller bearingsFor tapered roller bearings with high load and high speed, when adjusting the clearance, the effect of temperature rise on the axial clearance must be considered, and the reduction of the clearance caused by temperature rise must be estimated, that is, the axial clearance should be appropriately adjusted to a larger extent.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.
