12/05/2023
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.
Application：
382A/387A bearings are mainly used in chiller, milling machine, hotel equipment, pump and compressor, lifting table milling machine, fan, exhaust equipment, screw chiller, deep hole drilling machine, electric welding, cutting equipment, commercial vehicles, industrial fans, environmental protection equipment, and other major fields.
