FAG bearings

Whether it’s for cars, light or heavy industrial vehicles or tractors – thanks to the wide range of FAG solutions it is possible to meet every need in no time. All components are designed to work together perfectly and allow you to replace parts quickly and professionally.

FAG super precision bearings

FAG super precision bearings for main spindles stand for very high precision and absolute operational security. Innovative FAG spindle bearing solutions are continually raising standards in relation to speeds, accuracy and rating life. For the main spindle system and the overall machine tool system to be successful, however, bearing components alone are no longer sufficient as a guarantee.

Significant increases in performance and the creation of unique selling propositions for the customer are now achieved when the bearing manufacturer offers advice and carries out development work on the basis of wide-ranging system knowledge as well as being able to provide support through a range of service functions.

FAG cylindrical roller bearings

FAG super precision cylindrical roller bearings comprise solid outer rings, solid inner rings with a tapered bore (taper 1:12) and cylindrical roller and cage assemblies with cages made from brass or PEEK (polyether ether ketone). The outer ring is removable and can thus be mounted separately from the normal bearing package. The inner ring is only removable in the case of series NNU49.

The single and double row bearings are used when very high precision under very high radial load is required. Typical areas of application include machine tools and printing machinery. In these cases, they facilitate bearing arrangements with high accuracy, high radial rigidity and very high load carrying capacity. In machine tool building, they provide radial support for the main spindle.

FAG spindle bearings

FAG spindle bearings are super precision single row angular contact ball bearings with solid outer and inner rings, ball and cage assemblies and solid window cages. The dimensions are standardised. Due to their very narrow tolerances, the spindle bearings are particularly suitable for applications involving the highest requirements for guidance accuracy, such as bearing arrangements for main spindles in machine tools.

The bearings are available in all the designs that are relevant to bearing arrangements for main spindles in machine tools. This extensive product range gives the designer all possible scope for developing technically innovative, operationally secure and economical bearing arrangements.

FAG axial ball bearings

Double direction axial angular contact ball bearings 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 fitted 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 from one side. 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.
