China 30203 metric tapered roller bearings

Sales China 30203 metric tapered roller bearings

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an axial component will be generated, so when another bearing that can bear the axial force in the opposite direction is needed to be balanced.

Tapered roller bearings 30203 are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an axial component will be generated, so when another bearing that can bear the axial force in the opposite direction is needed to be balanced.

 

Tapered roller bearings refer to radial thrust rolling bearings in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads mainly with radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used alone to support pure axial loads. When configured in pairs (installed with the same name opposite), it can bear pure radial loads.
