Tapered roller bearings

The cone angle of the outer ring raceway of the single row tapered roller bearing is between 10 ° and 19 °, which can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to withstand axial loads. Large cone angle bearing, rear code plus B, cone angle between 25 ° ~ 29 °, it can withstand large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during installation. The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer, and the thickness of the spacer can also be used to adjust the pre-interference of the double row tapered roller bearing.

Tapered roller bearings

Single row tapered roller bearings have an outer ring, its inner ring and a set of tapered rollers by a basket cage package into an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing outline dimension standard, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve international interchange with the same type of outer ring or inner ring assembly. That is, in addition to the external dimensions and tolerances of the same type of outer ring, the cone angle and cone diameter of the inner ring assembly must also comply with the relevant provisions of interchange.
Generally, the taper angle of the outer ring raceway of the single row tapered roller bearing is between 10 ° and 19 °, which can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to withstand axial loads. Large cone angle bearing, rear code plus B, cone angle between 25 ° ~ 29 °, it can withstand large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer, and the thickness of the spacer can also be used to adjust the pre-interference of the double row tapered roller bearing.
Four-row tapered roller bearings, the performance of this kind of bearing is basically the same as that of double-row tapered roller bearings, but the radial load is greater than that of double-row tapered roller bearings, and the limit speed is slightly lower. It is mainly used for heavy machinery.
Multi-sealed double and four-row tapered roller bearings. The new design of the bearing is personalized, the traditional design method of the fully sealed bearing is changed, and the new sealing structure type combining sealing and dustproof is adopted to improve the sealing effect and the sealing performance. Multi-sealed double, four-row tapered roller bearings compared with open structure bearings, life increased by 20% to 40%; lubricant consumption reduced by 80%.
