Application of Tapered Roller Bearings 

Tapered roller bearings are split type bearings; The inner and outer rings of the bearing have tapered raceways. Based on the number of rows of installed rollers, this type of bearings is divided into single-row, double-row and four-row tapered roller bearings and other design types. Single row tapered roller bearings are capable of supporting radial load and axial load in the same direction. When a bearing perceives a radial load, an axial component arises, so another bearing is required that can perceive an axial force in the opposite direction to balance it.

The ability of a single row tapered roller bearing to carry axial load depends on the contact angle, that is, the angle of the outer ring raceway: the larger the angle, the higher the ability to carry axial load. Tapered roller bearings use single row tapered roller bearings. Car front hubs use a small double row tapered roller bearing. Four-row tapered roller bearings are used in large cold and hot rolling mills and other heavy equipment.

The outer ring angle and outer race diameter are already standardized to the same dimensions. They must not be changed during the design and manufacturing process. The outer race of a tapered roller bearing can be interchanged with the inner race worldwide.

Tapered roller bearings are mainly designed to carry radial load and radial-axial load. Compared to angular contact ball bearings, they have a higher load capacity and a lower maximum speed. A tapered roller bearing is capable of supporting an axial load in one direction and thereby limiting the axial displacement of a shaft or housing in one direction.

Tapered roller bearings primarily support combined radial and axial loads. The load-bearing capacity of a bearing depends on the angle of the outer ring raceway: the larger the angle, the higher the load-bearing capacity. The bearing is a split-type bearing and is divided into single-row, double-row and four-row tapered roller bearings. The clearance of single row tapered roller bearings must be adjusted during installation; The clearance of double-row and four-row tapered roller bearings is set at the manufacturer in accordance with customer requirements.

Tapered roller bearings have a tapered inner and outer ring with tapered rollers between them. All projection lines of the conical surfaces converge at one point on the bearing axis. This design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads. The axial load carrying capacity of a bearing is mainly determined by the contact angle α; the larger α, the higher the axial load capacity. The magnitude of the angle is expressed by the calculated coefficient e; The larger the e value, the larger the contact angle and the higher the bearing's suitability for supporting axial loads.

Tapered roller bearings are typically split, meaning the inner inner ring assembly with rollers and cage can be mounted separately on a tapered outer ring (outer ring).

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