China tapered roller bearing 30203

Sales China tapered roller bearing 30203

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).

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.


The basic dimensions of FQN tapered roller bearings are listed in the dimensional data sheet,

Single-row tapered roller bearings:

Inner diameter size range: 20mm~1270mm

Outer diameter range: 40mm~1465mm

Width size range: 15mm~240mm
