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.
