  • Rolling bearings

    Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
