FAG AMS series super precision bearings are components designed for applications where rotational accuracy, rigidity, and repeatability are critical. They are used in machine tool spindles, grinding heads, metrology equipment, and high-end positioning systems. Their tight tolerance construction allows high speeds with minimal friction and vibration. MR Accesorios Industriales markets this FAG line in Buenos Aires, Argentina, and advises you on choosing the right model for your application.

The AMS series designation is read as a code combining letters and numbers. The letters AMS identify the family of super precision bearings for spindles, and the number that follows—as in AMS20, AMS30, or AMS40—indicates the size or load capacity within the series. The higher the number, the larger the dimension and rigidity. Suffixes that may appear after the number provide information about internal design, preload, or cage type, and should be interpreted according to the manufacturer's catalog. To request a quote, send us the complete code as it appears on your equipment or drawing.

In Argentine industry, these bearings are found in spindles of milling machines, grinding machines, machining centers, and precision lathes. They are also used in measuring heads, rotary tables, optical equipment, and CNC systems where rotational error must be minimal. Tool and die shops, metrology laboratories, and automated production plants are some of the areas where the AMS series makes a difference in surface finish and spindle service life.

To select the correct bearing, consider the maximum operating speed, axial and radial load, and the type of lubrication available. The AMS series is usually mounted with interference fit on the shaft and in the housing, and requires extreme cleanliness during assembly. Alignment between supports is essential: small deviations generate parasitic loads and shorten bearing life. Sealing or shields should be chosen according to the environment: clean and controlled for maximum speed, or with protection for environments with particles.

FAG super precision bearings are interchangeable with those of other manufacturers that follow the same dimensional and precision standards. However, manufacturing tolerances, preload, and internal design may vary between brands. Therefore, when replacing a bearing, it is not enough that the external dimensions match: you must verify the precision class, internal clearance, and mounting conditions. If in doubt, contact us with the original code and application type.

If you need a FAG AMS series super precision bearing, write to us via WhatsApp with the code or model shown on your machine. At MR Accesorios Industriales we respond promptly and help you identify the correct variant for your equipment. We can also advise you on proper mounting and lubrication to maximize bearing service life.
