Tapered roller bearings

Tapered Roller Bearings

          Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing that can withstand the axial force in the opposite direction is needed to balance. The ability of a single row tapered roller bearing to withstand an axial load depends on the contact angle, ie the outer ring raceway angle, the greater the angle, the greater the axial load capacity. A large number of tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.

composition

          A single row tapered roller bearing has an outer ring with an inner ring and a set of tapered rollers surrounded by a basket-shaped cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimensions, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve internationality with the same type of outer ring or inner ring assembly. exchange.

use

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