Classification :
PRODUCT DETAILS
Bearing Composition：
Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed.
Single row tapered roller bearings can bear radial loads and single direction axial loads. When the bearing bears radial load, an axial component will be generated, so it needs another bearing that can bear the axial force in the opposite direction to balance it.

A single row tapered roller bearing has an outer ring, an inner ring and an inner ring assembly consisting of a set of tapered rollers enclosed by a basket cage.
The conical Angle of the outer ring raceway of a single row tapered roller bearing is between 10° and 19°, which can withstand the combined action of axial load and radial load at the same time. The larger the cone Angle, the greater the ability to bear axial load. Bearings with large tapered angles, rear code plus B, cone Angle between 25°~29°, it can bear large axial load. In addition, single-row tapered roller bearings can be adjusted during installation.
Characteristics of tapered roller bearings:
1.Suitable for heavy load mechanism, or impact load mechanism;
2.Can bear radial load and axial load at the same time;
3.Tapered stick bearings will have axial force, so they need to be used in pairs;
4.The operation speed is not suitable for high speed;
5.Good lubrication.
