Tapered roller bearing

Conical roller bearings can be separated, and the components consisting of the inner ring, rollers, and cage can be installed separately from the outer ring.

Product Features:

The corrected contact line between the roller and the raceway can reduce stress concentration. Conical roller bearings can withstand large radial and axial loads. Due to the fact that tapered roller bearings can only transmit unidirectional axial loads, another symmetrically installed tapered roller bearing is required to transmit axial loads in the opposite direction.

Conical roller bearings mainly bear radial and axial combined loads. 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 belongs to the separated type bearing, which is divided into single row, double row, and four row tapered roller bearings according to the number 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 is given according to user requirements at the time of product delivery and does not require user adjustment.

Conical roller bearings have conical inner and outer raceway, with tapered rollers arranged between the two. All projection lines of conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for withstanding composite (radial and axial) loads. The axial load capacity of bearings is largely determined by the contact angle α; The larger the alpha angle, the higher the axial load capacity. The angle size is represented by the calculation coefficient e; The larger the value of e, the greater the contact angle, and the greater the applicability of the bearing to withstand axial loads.

Conical roller bearings are usually of the separated type, which means that the conical inner ring assembly consisting of rollers and cage components can be installed separately from the conical outer ring (outer ring).

Scope of use:

The most commonly used tapered roller bearing is the single row tapered roller bearing. In recent years, small-sized double row tapered roller bearings have also been used in the front wheel hubs of sedans. Four row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.

Conical roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
