Inch Single Row Tapered Roller Bearings Structure:
Inch single row tapered roller bearings contain outer ring, inner ring, cage and rollers. The outer ring (cup) can be separated from the inner ring assembly(cone).
Generally, the tapered angle of the outer ring raceway of a single-row tapered roller bearing is 10°~19°, which can bear the combined action of bearing load and radial load at the same time. The greater the cone angle, the greater the ability to withstand axial load.
Bearings with large taper angle, add B to the suffix code, and the taper angle is between 25°~29°, which can bear larger axial load.
In addition, users can adjust the clearance of single-row tapered roller bearings during the installation process.
Features:
1. Rated dynamic load ratio 1.5~2.5
2. Bearings can bear unidirectional axial load, additional axial force will be generated under the action of radial load, generally used in pairs
3. Single row tapered bearings can limit the axial displacement of the shaft and the housing in one direction
4. Low limit speed
