Angular contact ball bearing comprises an outer race, an inner
race, a row of steel balls and a holder. This type of bearing can
simultaneously subject to radial load and axial load. It can also
be subject to pure axial load and operate in high-speed. Single-row
angular contact ball bearing can only be subject to axial load from
one direction. When being subject to radial, additional axial force
will be caused, and only the axial displacement of shaft and
housing in one direction will be limited.
