The AN series lock nut is a fastening component used to secure bearings and other elements to the shaft. It is used together with a lock washer to prevent the nut from loosening due to vibration. It is a key part in bearing mounting in industrial machinery, where secure and precise fastening is required. MR Accesorios Industriales sells this NSK lock nut series in Buenos Aires, Argentina.

The AN series designation consists of the letters AN followed by a two-digit number that indicates the size. For example, AN 02, AN 03, AN 04 and AN 05 correspond to nuts of different dimensions. The number is not a direct diameter, but a code related to the shaft diameter and the bearing to be secured. To select the correct nut, you must identify the bearing and consult the equivalence table. If you have doubts, send us the bearing part number and we will advise you.

These nuts are used in a wide variety of industrial applications in Argentina: from machine tools and transmission equipment to pumps, fans and conveyors. They are common in the maintenance of manufacturing plants, metalworking workshops and agro-industrial facilities. They are also used in the mining sector and in the food industry, where equipment requires reliable assemblies. MR Accesorios Industriales sells them throughout the country.

For correct mounting, it is important to use the appropriate lock washer, which locks the nut in a groove on the shaft. The nut is tightened with a hook wrench or a socket wrench. It is recommended to clean the threads and apply a suitable lubricant to facilitate adjustment and prevent seizing. The alignment of the assembly is essential so that the bearing works without additional stresses. If you need assistance, contact us.
