FAG Double direction axial angular contact ball bearings of series 2344 are highly rigid, axially preloaded super precision bearings with restricted tolerances to class SP for the bearing arrangements of precision spindles in machine tools. These bearings without self-retention comprise solid shaft locating washers, a spacer ring, a housing locating washer and ball and cage assemblies with solid cages. The bearing parts are matched to each other and can be mounted separately, but must not be interchanged with parts from bearings of the same size. Due to the contact angle of 60 degree, they can support high axial forces. In bearing arrangements of main spindles, the axial angular contact ball bearing is combined with a double row cylindrical roller bearing with a tapered bore, which supports the radial forces.
