Self-aligning ball bearings are characterised by their ability to automatically compensate for misalignment and shaft displacement. They consist of an inner ring with a cylindrical or tapered bore, an outer ring with a spherical raceway and two rows of balls that ensure even load distribution.
This bearing design combines smooth running with high operational reliability and is particularly suitable for applications where assembly tolerances or shaft deflections may occur. Despite their compensating ability, they offer stable running accuracy and can absorb not only radial but also low axial forces.
Thanks to their robust design and availability in open or sealed versions, self-aligning ball bearings are used in numerous industrial sectors – from drive systems and conveyor systems to agricultural machinery.
