The drawings:
EE640192/640260-BB bearings are single row tapered roller bearings with a flanged outer ring to facilitate axial location.
As different row configurations for rollers are required, tapered roller bearings can also be divided into double row tapered roller bearings and four-row tapered roller bearings. These bearings have the advantage of combined load capacity in both radial and axial environments. Compared to other bearings of the same size, these tapered roller bearings have a relatively longer working life.
Tapered roller bearings are widely used in automotive, machine tool spindles, mining, gear reduction units, plastics machinery and a host of other industries.
