Feature:

This bearing can adapt to the combination of radial and axial loads and provide low friction during operation. Its inner ring can be installed separately from the outer ring, so it is convenient for installation, disassembly and maintenance. Rigid bearing applications can be achieved by installing one single row tapered roller bearing on another and applying preload.

Applications of 30220 Single row tapered roller bearing:

It is widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
