Online search, there is no one icon. The outer diameter of a cone does not have two ends, a big head and a small head. What end is the outer diameter of the cone as its outer diameter?
Tapered roller bearings are not only one of the outer diameter, the roller is tapered, and if you are using bearings, then regardless of it, if the design, there are national standards
The outer diameter of the tapered roller bearing is one, and the outer ring is cylindrical, so the outer diameter is the same. You say a big head, a small head, should be tapered roller bearings in the outer ring of the inner diameter, both ends of a big diameter, a small diameter, that is the size of the outer ring, the overall bearing on a diameter.
Tapered roller bearings, the outer circle of the cylinder or a cylinder, there is no size of the end of the hole; the same is true of the bore.Tapered roller bearings, it is the same as ordinary cone roller, roller (ball, roller) bearings, tapered roller bearings can bear radial load, also can withstand the axial load (axial force). Therefore, when the tapered roller bearings are mounted on the shaft, pay attention to the direction of its installation.
The outer diameter of the tapered roller bearing is one, and the outer ring is cylindrical, so the outer diameter is the same.It is called a tapered roller bearing, because its roller is a cone, and the whole of the bearing is an outer ring and an inner ring.The tapered roller bearings belong to separate bearings, and the inner and outer rings of the bearing have tapered raceways. The bearings are divided into single row, double row and four row tapered roller bearings according to the number of rollers arranged. Single row tapered roller bearings can bear radial loads and axial loads in a single direction. When the bearing is subjected to radial load, an axial component is produced, so that when another bearing is required to bear the axial force in the opposite direction, it will be balanced.
