SKF tapered roller bearing

SKF tapered roller bearings can be separated, and the components composed of the inner ring, the rollers and the cage and the outer ring can be installed separately.

Product Features:
Corrected contact lines at roller and raceway contact reduce stress concentrations. SKF tapered roller bearings can withstand large radial and axial loads. Since tapered roller bearings can only transmit axial loads in one direction, another symmetrically mounted tapered roller bearing is required to transmit axial loads in the opposite direction.

Tapered roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing 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 the user's requirements when the product leaves the factory, and does not need to be adjusted by the user.

Tapered roller bearings have tapered inner and outer raceways with tapered rollers arranged in between. The projected 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 the 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 represented 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 the inner ring with the roller and cage assembly can be installed separately from the tapered outer ring (outer ring).

Scope of use:
The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hubs of cars, small-sized double-row tapered roller bearings have also been used in recent years. Four-row tapered roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.

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