FAG super precision bearings are components designed for applications where running accuracy, rigidity and repeatability are critical. They are used in machine tool spindles, measuring equipment, instrumentation and high-demand positioning systems. MR Accesorios Industriales supplies this FAG line in Buenos Aires, Argentina, and helps you identify the correct designation for your equipment.

The designation of these bearings is read in blocks. The initial letter M identifies the super precision series. The number that follows indicates the size: for example, M7005 corresponds to a 25 mm bore, M7006 to 30 mm, M7007 to 35 mm, and so on. The suffix E indicates a 25° contact angle. The combination T and P4S defines the execution: T indicates a single row bearing with a synthetic material cage, and P4S is the super precision accuracy class according to the standard. The suffix XL identifies the current generation of the product, with improvements in design and lubrication.

These bearings are used in milling machine, grinding machine and machining center spindles, where speed and precision are decisive. They are also found in measuring heads, rotary tables, optical equipment and high-resolution positioning systems. In Argentina, you will find them in the metalworking, automotive, aeronautical and machine tool industries, as well as in laboratories and grinding shops that require very tight tolerances.

To select the correct bearing, take the arrangement into account: these bearings are usually mounted in pairs, in back-to-back or face-to-face configuration, depending on the rigidity and tilting moment required by the spindle. Lubrication is critical: high-speed, clean oil or grease is recommended, and the specified quantity must be respected to avoid overheating. Shaft alignment and housing fit must be very precise; any deviation affects service life. Sealing, where applicable, protects against contaminants without increasing running torque.

As for equivalences, super precision bearings are identified by their complete designation, which includes series, dimensions, contact angle, precision class and execution. When looking for a replacement, bore and width are not enough: the contact angle, precision class and cage type must also match. Different manufacturers use their own nomenclatures, so interchangeability requires comparing technical characteristics and not just the part number. If you have doubts, send us the complete part number and we will advise you.

If you need an FAG super precision bearing for your machine, write to us via WhatsApp with the part number or model shown on the drawing or on the old bearing. At MR Accesorios Industriales we reply promptly and help you confirm the exact designation. We can also quote equivalent alternatives if the original part number is not available.
