Single-row tapered roller bearings can adjust the clearance during installation

Tapered roller bearing single row tapered roller bearing has an outer ring, its inner ring and set of tapered rollers is an inner ring assembly composed of a basket-shaped cage. The outer ring can be separated from the inner ring component. According to the ISO standard for external dimensions of tapered roller bearings, the outer ring or inner ring component of any standard tapered roller bearing should be able to achieve internationality with the outer ring or inner ring component of the same model. exchange. That is to say, in addition to the outer dimensions and tolerances of the same model, the outside diameter and tolerances must meet the requirements of ISO492 (GB307), and the cone angle of the inner ring components and the diameter of the component cones must also meet the relevant regulations for interchange.

Generally, the tapered angle of the outer ring raceway of a single-row tapered roller bearing is 10 ° ~ 19 °, and it can simultaneously bear the combined action of axial load and radial load. The larger the cone angle, the greater the ability to withstand axial loads. Bearings with a large tapered angle, with a post code plus B, with a tapered angle between 25 ° and 29 °, can withstand large axial loads. In addition, single-row tapered roller bearings can adjust the amount of clearance during installation.

The outer ring (or inner ring) of a double-row tapered roller bearing is a whole. The two small inner end faces of the inner ring (or outer ring) are close to each other 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.

Four-row tapered roller bearings. The performance of this kind of bearings is basically the same as double-row tapered roller bearings, but it has a larger radial load and a lower limit speed than double-row tapered roller bearings. It is mainly used in heavy machinery, such as Rolling mill, etc.

Multi-sealed double and four-row tapered roller bearings, provides long-life, multi-sealed double and four-row tapered roller bearings. The bearing is individually and completely new designed, and the traditional design method of fully sealed bearings is changed. A new type of sealing structure combining sealing and dustproof is adopted to improve the sealing effect and sealing performance. Compared with open structure bearings, multi-sealed double-row and four-row tapered roller bearings have a 20% to 40% longer life and a 80% reduction in lubricant consumption.
