Ball bearings and roller bearings are manufactured today in a variety of designs. They all share the characteristic advantages of rolling bearings, primarily low friction and high load capacity. Rolling bearings also require minimal effort for lubrication. Furthermore, they have standardized installation dimensions and tolerances that facilitate replacement. Due to these distinctive advantages, rolling bearings have gained significant importance in technology. Initially, differences in the design of the bearings were not crucial. However, to keep up with the constantly increasing demands on the performance of rolling bearings, the differences in design must be given more attention than before; as each design has its typical force transmission and movement relationships between rolling elements and raceways. This leads to differences.
