Tapered roller bearings mainly bear combined radial and axial loads
The load capacity of the bearing depends on the raceway angle of the outer ring, the greater the angle, the greater the load capacity. This type of bearing is a separable 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 clearance of double-row and four-row tapered roller bearings has been given according to user requirements when the product leaves the factory, and no user adjustment is required.
Tapered roller bearings have tapered inner and outer ring raceways with tapered rollers arranged in between
The projection lines of all conical surfaces meet at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for combined (radial and axial) loads. The axial load capacity of a bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the larger the value of e, the larger the contact angle, and the greater the applicability of the bearing to bear the axial load.
Tapered roller bearings are usually separable, that is, the tapered inner ring assembly consisting of an inner ring with a roller and cage assembly can be mounted separately from the tapered outer ring (outer ring).
Tapered roller bearings are produced by Industrial bearing china suppliers manufacturers and are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
