Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, it has larger load capacity and lower limit speed. Tapered roller bearings can withstand axial loads in one direction and limit axial displacement of the shaft or housing in one direction.
Single row tapered roller bearings have an outer ring, an inner ring and a set of tapered rollers enclosed by a basket-shaped cage into an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimension standard, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve international compatibility with the same type of outer ring or inner ring assembly. exchange.
Usually, the taper angle of the outer ring raceway of a single row tapered roller bearing is between 10° and 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 withstand axial loads. For bearings with a large cone angle, add B to the post code, and the cone angle is between 25° and 29°, which can withstand large axial loads. In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
