FAG spindle bearings features are units comprising solid inner and outer rings and ball and cage assemblies with solid window cages made from hard fabric.

They are particularly suitable for bearing arrangements with very high guidance accuracy and high speeds.
They are principally for machine tool spindles;have restricted tolerances tolerance class P4S.They cannot be dismantled.They can support axial loads in one direction as well as radial loads ,due to the contact angle of 15 are generally fitted in pairs in an O o r X arrangement,can therefore support axial forces from both directions and moments.
