Classification And Using Precaution Of Tapered Roller Bearings Classification of tapered roller bearings Single row tapered roller bearing The single-row tapered roller bearing has an outer ring, an inner ring assembly of which an inner ring and two tapered rollers are enclosed by a basket-shaped cage. The outer ring will be separated from the inner ring component. According to the ISO tapered roller bearing size standard, the outer ring or inner ring component of any standard tapered roller bearing should be able to achieve international interaction with the outer ring or inner ring component of the same model change.

That is, in addition to the outer dimensions and tolerances of the same type of outer ring of the same model must comply with ISO492 (GB307) regulations, the cone angle of the inner ring components, the cone diameter of the components must also meet the relevant regulations of the interchange.


Generally, the tapered angle of the outer ring raceway of a single-row tapered roller bearing is between 10 째 and 19 째, and it can withstand the combined effects of vertical incidence and gradation. Big. Bearings with a large tapered angle, with code plus B, with a tapered angle between 25 째 - 29 째, it can withstand truncated insertion displacement. In addition, single-row tapered roller bearings can adjust the amount of clearance during installation.

Double-row tapered roller bearings The outer ring / inner ring of the double-row tapered roller bearing is a whole. The two inner rings / outer rings have very similar small ends and a spacer in the middle. The clearance will be adjusted by the thickness of the spacer. The thickness of the spacer can be used to adjust the pre-interference of the double-row tapered roller bearing as well.

Four-row tapered roller bearings Four-row tapered roller bearings, the performance of basic bearings is basically the same as double-row tapered roller bearings, but the radial deviation withstands the double-row tapered roller bearings, the limit is slightly lower, mainly used in heavy machinery.


Multi-sealed double and four-row tapered roller bearings Multi-sealed double and four-row tapered roller bearings, Spark offers long life, multi-sealed double and four-row tapered roller bearings. Individually designed new bearings changed the traditional design method of fully sealed bearings and adopted a combination of sealing and dustproof. Multi-seal double, four-row tapered roller bearings and open structure bearings benchmark, life expectancy, increased by 20% to 40%; consumption and consumption The amount is reduced by 80%.

Precautions for using tapered roller bearings 1. Keep tapered roller bearings and their surroundings clean. Even small dust that cannot be seen by the eyes can have a bad effect on the bearings. Therefore, keep the surroundings clean so that dust does not enter the bearings.

2. Be careful when using.


The tapered roller bearing is strongly impacted during use, which may cause scars and indentations, which may cause accidents. In severe cases, cracks and breaks may occur, so care must be taken.

3. Use appropriate operating tools. You should avoid using existing tools instead, and you must use the right tools.

4. Pay attention to the corrosion of tapered roller bearings. When operating the bearings, sweat from your hands can cause rust. Pay more attention to the operation with clean hands, and it is best to wear gloves.
