Ball bearings consist of two hardened metal rings separated by a
set number of perfectly spherical steel balls spaced equilaterally
with a bearing cage. The balls run along concave grooves set into
the rings placed one inside the other. Ball bearings can be found
in everything from the washing machines to computers. The ball
bearing system requires a thin film of lubricant for high -speed
applicationsto reduce friction and facilitate heat dissipation,
corrosion prevention, and long bearing life. The raceways and the
balls both have a fine surface finish and with proper lubrication
less noise, less torque and long life, all can be achieved. Ball
bearings require one time lubrication that happens during the
manufacture. Ball bearings may fail due to improper lubrication,
excessive temperature or if the bearing or the raceway has been
damaged. Deep groove ball bearing have the features of simple
structure, easyusage, small friction and high rotating speed, etc.
Which is the mostpopular bearing in applications. It can bear
radial loads and axial loads from both directions. And can meet the
requirements of high speed and low noise. Except the basic
structure of ***0 type the deep groove ball bearing with
dust-prevention cover and seal ring and the bearing with slot and
without cage are also available.
