Tapered roller bearings can bear radial load and unidirectional axial load. When a load is applied to the bearing, an axial component of force will be generated. Therefore, like angular contact ball bearings, two bearings are generally used oppositely, or they must be used in the form of double-row bearings. In this case, you can adjust the distance between the inner ring or the outer ring to set a proper internal clearance.
Introduction to sub-categories:
In terms of design, the raceway surfaces of the inner ring and outer ring of the Tapping machine bearing and the conical apex of the roller converge at a point on the central axis of the bearing. The truncated cone-shaped roller is assembled in the bearing as a rolling element and guided by the large rib of the inner ring.

Tapered roller bearings Advantage:
1. High speed and high precision
2. Long service life
3. Lowest noise and good performance
Tapered roller bearings are generally used to bear compound loads dominated by radial loads. Their cups are separable and easy to assemble. In the process of installation and use, the radial clearance and axial clearance can be adjusted, and pre tightening installation can be carried out.
Tapered roller bearings are uniquely designed to manage thrust and radial loads on rotating shafts and bearing pedestals.
Tapered roller bearing is designed to bear thrust and radial load, and is composed of four parts: cone or inner ring; Cup or outer ring; Tapered roller or rolling element; And cage or roller cage.
Tapered roller bearings mainly bear combined radial and axial loads, mainly radial loads. The axial bearing capacity depends on the contact angle of the outer race. The larger the contact angle, the larger the capacity.
The included angle between the outer raceway bus of tapered roller bearing and the straight line. This bearing can bear heavy load and other tapered roller bearings. It mainly bears the combined load based on unidirectional axial load, not just radial load.
Tapered roller bearings have tapered inner and outer raceways, and tapered rollers are in the middle of the two raceways. This kind of bearing is usually separable, that is, the cage, inner ring and outer ring can be installed separately. They can bear huge radial load and certain axial load. They are designed in different sizes and styles to meet various functions.

Classification of tapered roller bearings
A single row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are an inner ring assembly enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO taper roller bearing outline dimension standard, the outer ring or inner ring assembly of any standard model of taper roller bearing should be internationally interchangeable with the outer ring or inner ring assembly of the same model. That is, the outer ring of the same model must comply with the provisions of iso492 (gb307) in terms of external dimensions and tolerances, and the cone angle and cone diameter of inner ring components must also comply with the relevant provisions of interchangeability.
Generally, the taper angle of the outer race of single row tapered roller bearings is between 10 ° ~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 bear axial load. For bearings with large cone angle, post code plus B, the cone angle is between 25 ° ~29 °, and it can bear large axial load. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.
The outer ring (or inner ring) of double row tapered roller bearings 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. The thickness of the spacer can also be used to adjust the pre interference of double row tapered roller bearings.
The performance of four row tapered roller bearing is basically the same as that of double row tapered roller bearing, but it bears more radial load than double row tapered roller bearing, and its limit speed is slightly lower. It is mainly used in heavy machinery.
Multi seal double and four row tapered roller bearings, ZWZ provides long-life, multi seal double and four row tapered roller bearings. Carry out personalized new design for bearings, change the traditional design method of fully sealed bearings, and adopt a new sealing structure combining sealing and dust prevention, so as to improve the sealing effect and sealing performance. Compared with open structure bearings, the service life of multi seal double and four row tapered roller bearings is increased by 20% – 40%; Lubricant consumption is reduced by 80%.
