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

Tapered roller bearings are mainly subjected to radial and axial joint loads. Bearing capacity depends on the outer ring of the rolling angle, the greater the angle the greater the carrying capacity. The bearing of this kind of bearing is a kind of separation type bearing, which is divided into single row, double row and four row tapered roller bearing according to the number of rolling elements in the bearing.

Single row tapered roller bearing clearance to be adjusted during installation the user; double row and four row tapered roller bearing clearance have been in the factory according to user requirements given, do not need to adjust the user. Tapered roller bearings with tapered inner and outer ring, tapered roller arranged between the two. The projection lines of all conical surfaces are gathered at the same point on the axis of the bearing. This design makes tapered roller bearings especially suitable for bearing the load of composite (radial and axial) loads. The axial load capacity of the bearing is determined by the contact angle. From the angle of view, the E value is expressed as the E value, the greater the contact angle is, the higher the bearing axial load is.

Tapered roller bearings are usually separated type, that is, the inner ring of the inner ring of the roller and cage assembly can be separated from the outer ring (outer ring).
