​​Bearings-General bearings-Self-aligning ball bearings

Picture
Self-aligning ball bearings have two rows of balls with a common sphered raceway in the out ring. This feature give the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. They are therefore particularly suitable for applications where misalignment can arise form errors in mounting or from shaft deflection.

These bearings of the basic design are available with a cylindrical bore as well as with tapered bore. For self-aligning ball bearings with tapered bore, we supply appropriate adapter sleeves with which the bearings can be secured to shafts.
