Product features:
The modified contact line at the contact between roller and raceway can reduce the stress concentration. SKF tapered roller bearing can bear large radial load and axial load. Because tapered roller bearing can only transmit one-way axial load, another tapered roller bearing installed symmetrically with it is needed to transmit axial load in the opposite direction.
Tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity depends on the raceway angle of the outer ring. The greater the angle, the greater the bearing capacity. This kind of bearing is a separate 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 bearing 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 products leave the factory and does not need to be adjusted by the user.
Tapered roller bearings have conical inner ring and outer ring raceways, and tapered rollers are arranged between them. The projection lines of all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α Determined; α The greater the angle, the higher the axial load capacity. The angle is expressed by the calculation coefficient E; The larger the angle of E, the more applicable the bearing will be.
Tapered roller bearings are usually separate type, that is, the tapered inner ring assembly composed of the inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring).
Scope of use:
Single row tapered roller bearings are the most used tapered roller bearings. In recent years, double row tapered roller bearings have been used in the wheel hubs of cars. Four row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
