Tapered roller bearings mainly bear radial and axial combined loads. Bearing capacity depends on the raceway Angle of the outer ring. The greater the Angle, the greater the bearing capacity. This kind of bearing belongs to separated type bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of the rolling body in the bearing. Single row tapered roller bearing clearance needs to be adjusted by the user during installation; Double row and four row tapered roller bearing clearance has been given according to user's requirements when the product is delivered, without user adjustment.

Tapered roller bearings have conical inner ring and outer ring raceway, tapered roller arranged between the two. The projection lines of all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing composite (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact Angle α. The larger the α Angle, the higher the axial load capacity. The Angle is represented by the calculation coefficient E; The greater the E value, the greater the contact Angle, the greater the applicability of bearing to bear axial load.

Tapered roller bearings are usually of separate type, that is, the tapered inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the tapered outer ring (outer ring).

Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
