Bearings Self Aligning Ball Bearings
View our extensive range of metric self aligning ball bearings here at Bearingboys, suitable for applications where shaft misalignments are expected. These bearings have two ball rows with a common concave raceway, making them self-aligning and insensitive to angular issues. With brands like SKF, NSK, FAG and more, we stock all popular sizes from 5mm to 120mm bore diameters. Self aligning bearings offer very low friction, enabling high speed operation. We also stock sealed versions for contaminated environments. Please call or email us if you need help selecting the right bearing.
