The type code of tapered roller bearing is 30000. Tapered roller bearing is a separate bearing. The angle of outer ring and the diameter of outer raceway are the same as the overall dimensions and have been standardized. It is not allowed to change during design and manufacturing. So that the outer ring and inner components of tapered roller bearing can be interchanged all over the world.
Tapered roller bearings are mainly used to bear the combined radial and axial load dominated by radial load. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction.
Single row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are an inner ring assembly composed of basket cage. The outer ring can be separated from the inner ring assembly. According to the provisions of ISO tapered roller bearing overall dimension standard, the outer ring or inner ring assembly of any standard model of tapered roller bearing shall be able to realize international exchange with the outer ring or inner ring assembly of the same model.
Generally, the taper angle of the outer race of single row tapered roller bearing is between 10 ° ~ 19 °, which can bear the combined action of axial load and radial load at the same time. The greater the cone angle, the greater the ability to bear axial load. For the bearing with large cone angle, the post code plus B, and the cone angle is between 25 ° ~ 29 °, it can bear large axial load. In addition, the single row tapered roller bearings can adjust the clearance size during the installation process.
The outer ring (or inner ring) of double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are close, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre interference of the double row tapered roller bearing.
