Tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load carrying capacity. This type of bearing is a split type bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the double-row and four-row tapered roller bearing clearances are given according to user requirements when the product leaves the factory, and no user adjustment is required.
Tapered roller bearings have a conical inner ring and an outer ring raceway, and tapered rollers are arranged between the two. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the angle α, the higher the axial load capacity. The angle size is expressed by the calculation coefficient e; the larger the e value, the larger the contact angle, and the greater the applicability of the bearing to the axial load.
Tapered roller bearings are usually of a separate type, ie a conical inner ring assembly consisting of an inner ring with a roller and cage assembly can be mounted separately from the outer bevel (outer ring).
Tapered roller tilting pad radial bearing are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
