The two fundamental types of rolling bearing are distinguished by two basic types of rolling element. The two basic types of rolling bearings are shown below:

With minimal friction, rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles, or wheels – and transfer loads between machine components. Rolling bearings provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption, and wear. They are exchangeable and cost-effective machine elements that typically follow national or international dimension standards.
