Item name:Tapered roller bearing

Model: 30000 series, 350000 series

Application: Automobile, Rolling mill, Mining, Metallurgy, Plastic machinery , etc.

Description: Tapered roller bearing comprised by inner ring, roller , retainer and outer ring, which can be installed separately. This kind of bearing can support heavy radial load and axial load. Due to tapered roller bearing can only transfer one-way axial load, we need to install a symmetric tapered roller bearing to transfer the opposite direction axial load. This kind of bearing include single row , double-row and four-row tapered roller bearing according to the column number of roller. The clearance of single row tapered roller bearing need a adjustment during installation. And the clearance of double-row and four-row tapered roller bearing has been adjusted according to the users' requirement and need not to adjust.

The outer ring and inner ring components of single-row tapered roller bearings are separate, in accordance with the provisions of ISO size standard for tapered roller bearings, any one of the standard model of inner ring of tapered roller bearing outer ring or components should be able to and within the outer ring of the same model or component of international exchange. The outer rings of the same model except the external dimensions, tolerances, subject to ISO492 (GB307) requirements, the inner diameter of the cone angle of a component and component cone also comply with the relevant provisions of the exchange.

In General, the tapered angle of outer ring raceway is 10 ° ~19 °, single-row tapered roller bearings can endure axial load and radial load at the same time. Then larger angle, the more axial load that can endure. Plus "B" after the code when the bearings with large cone angle. It can withstand larger axial load when the angle is between 25 ° ~29 °. You can adjust the clearance in the installation process.

The outer ring(or inner ring ) of double-row tapered roller bearings are a whole. The small faces of the inner rings (or outer) are similar, and space ring in the middle. Thickness adjusts the clearance.

The function of four-row tapered roller bearings is the same as double-row tapered roller bearings. But it can endure larger radial load. The limit rotation speed is a little lower. Mainly applied in heavy-duty machinery, such as rolling mills.

OKB supply the bearings with long life and much sealed double-row or four-row tapered roller bearings. The life of this kind of bearings are 20%-40% longer but lubrication consumption is 80% lower than open structure bearings.

Suffix definition:

A: change of internal structure

B: increasing contact angles

X: Overall dimensions using international standards

CD: double outer rings with oil hole or groove

TD:double inner rings with tapered bore
