Where are ball bearings used? And what types are there?
Ball bearings have become indispensable in mechanical engineering. There are various ball bearing designs for which mass and technical composition of the components depend on the specifications of the industrial application. The following list shows the most commonly used ball bearings
and where they are used.
Deep groove ball bearing according to DIN 625:This type of ball bearing
absorbs radial forces and is used wherever components rotate. In the automotive industry, for example, deep groove ball bearings can be found in the chassis, where they
support and guide the axes. There is always radial force when the axis rotates.
Angular ball bearing based on DIN 628:This bearing is designed to support both
radial and
axial forces in one direction. Angular ball bearings
make higher speeds possible and
reduce friction for a wide range of loads. Angular ball bearings are used in the bicycle industry, the automotive sector or, for example, in the spindles of machine tools.
Self-aligning ball bearing based on DIN 630:This type of ball bearing is generally used in
applications with long shafts. This is associated with the assembly problems arising from holes in the housing. Axial forces are important in self-aligning ball bearings. These forces need to be kept low, since the running grooves in the outer race have limited contact surfaces for the rolling elements. This type is used for general-purpose mechanical engineering.
Thrust bearing according to DIN 711:As the name of the bearing suggests, this ball bearing is designed to support
axial loads. They are available in a
single-row or
double-row version and are already in use in numerous applications in the medical technology and packaging industries.
