FAG Axial angular contact ball bearings
Features
Axial angular contact ball bearings 2344
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°, 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.
Axial bearings BAX
The bearing arrangement of main spindles in machine tools are subjected to high demands. They must have high load carrying capacity and must at the same time also be suitable for high spindle speeds. Increased load carrying capacity normally brings with it a reduction in the maximum speed. Through the use of the new axial bearings BAX, it is now possible to unify both requirements.
The axial bearings:
Can support high axial loads
Have the speed capacity of main spindle bearings
Have high rigidity
Can support axial loads only.
The axial bearings BAX conform to the accuracy class P4S and are in principle supplied as ready-to-fit sets in the arrangement DB. Axial bearings BAX correspond in their dimensions to bearings of size 70. They are thus matched to the diameters of cylindrical roller bearings N10 and NN30. The outside diameter tolerance is designed to give a loose fit when the seats of the axial angular contact ball bearing and the cylindrical roller bearing are machined together. Axial bearings BAX are available with a contact angle of 30° and, for even higher rigidities, also with a contact angle of 40°.
Lubrication
The bearings can be lubricated with oil or grease.
