Classification and Characteristics of Tapered Roller Bearings

What is tapered roller bearing
Tapered roller bearings belong to separate bearings, bearing inner and outer rings have tapered raceway. This kind of bearing can be divided into single row, double row and four row tapered roller bearing according to the number of roller rows installed.

Structural characteristics of tapered roller bearings
1. Tapered roller bearings are separated bearings. Under normal circumstances, especially in GB/T307.1-94 "Rolling Bearings Centripetal Bearing Tolerances", the outer ring and inner component of tapered roller bearings within the size range involved are 100% universal and interchangeable.
2. The Angle of the outer ring of tapered roller bearings and the diameter of the outer raceway have been standardized as well as the outer dimension. It is not allowed to change during design and manufacture. In order to make the taper roller bearing between the outer ring and the inner component can be used in the world.
3. Tapered roller bearings are mainly used for bearing combined radial and axial loads, which are mainly radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low.

Category and characteristics of tapered roller bearings
Tapered roller bearings can be mainly divided into the following four categories:
1. Single-row tapered roller bearings: the bearing's ability to bear axial load depends on the contact Angle, that is, the outer ring raceway Angle. The greater the Angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearings. Double row tapered roller bearings of small size are used in the front wheel hub of the car. Four rows of tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
2. Double row tapered roller bearings: the outer ring (or inner ring) of the 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.
3. Four row tapered roller bearings: the performance of this bearing and double row tapered roller bearings are basically the same, but than double row tapered roller bearings bear greater radial load, the limit speed is slightly lower, mainly used in heavy machinery, such as rolling mill.

4. Multi-sealed double and four-row tapered roller bearings: personalized new design for bearings, change the traditional design method of fully sealed bearings, adopt a new sealing structure combining sealing and dustproof to improve the sealing effect and sealing performance. Compared with open structure bearings, the life of multi-sealed double and four-row tapered roller bearings can be increased by 20% ~ 40%. Lubricant consumption reduced by 80%.
