Single Row Metric Size Tapered Roller Bearing

Time：2020.04.07  Source：Roller Bearings Suppliers

Tapered roller bearings are separate bearings, and the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single row, double row and four row tapered roller bearings according to the number of roller rows installed. Single-row tapered roller bearings can withstand 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 withstand the axial force in the opposite direction is needed to balance it.

The tapered roller bearing refers to a radial thrust rolling bearing whose 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 dominated by radial loads. It is often used in dual, reverse installation. 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 combined axial and radial loads that are mainly axial loads. It is generally not used alone to withstand pure axial loads. It can be used to withstand pure radial loads when configured in pairs (relatively installed at the same end).

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

Today’s model explanation:

Single row metric size tapered roller bearings 32303

Inner diameter size range: 20mm ～ 1270mm

Outer diameter size range: 40mm ～ 1465mm

Width size range: 15mm ～ 240mm

Generally, the tapered angle of the outer ring raceway of a single row tapered roller bearing is between 10 ° and 19 °, which can simultaneously bear the combined action of axial load and radial load. The larger the cone angle, the greater the ability to withstand axial loads. Bearings with a large cone angle, the rear code is added with B, and the cone angle is between 25 ° ~ 29 °, which can bear a large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
