FAG XC series super precision bearings are components designed for applications where rotational accuracy and rigidity are critical. They are used in machine tool spindles, measuring equipment and high-speed systems. MR Accesorios Industriales supplies this line as a brand, with technical advice to select the right configuration for the application.

The designation of the XC series is interpreted in blocks. The initial letters identify the super precision family; the number that follows indicates the size. The suffix E indicates an optimized design, T a phenolic material cage, and P4S the super precision tolerance class. For example, XC7000-E-T-P4S and XC7004-E-T-P4S share the same structure and differ in size. Knowing these codes allows you to order the exact replacement.

In Argentine industry, these bearings are used in the spindles of milling machines, grinding machines and machining centers, as well as in metrology equipment and test benches. They also appear in high-speed applications where heat dissipation and dimensional precision are decisive. Die-making, automotive and aerospace workshops turn to this series when clearance and rigidity must remain stable.

To select correctly, you must consider the arrangement (individual, paired or tandem), the cage type, the axial and radial clearance, and the lubrication system. Mounting requires extreme cleanliness, precise alignment and preload control. Lubrication can be grease or oil, depending on the speed and working temperature. Proper sealing prevents contamination, which is the main cause of premature failure.

There are equivalences between manufacturers for super precision bearings, but they are not automatic: tolerances, cages and load capacities change. Therefore, when replacing a bearing, it is advisable to verify the complete designation and the operating conditions. MR Accesorios Industriales can advise on alternatives within the same brand or other lines, always respecting the specifications of the original equipment.
