The NTN AW series lock washer is a fastening component used to secure bearings and prevent adjusting nuts from loosening due to vibration. It is placed between the nut and the bearing, and its tab is bent over a slot on the shaft or the nut to lock the assembly. It is a key part in assemblies requiring high reliability, such as transmissions, pumps and industrial equipment. MR Accesorios Industriales sells this series with the backing of NTN.

The designation of the AW series is interpreted as follows: the letters AW identify the lock washer family, and the number that follows indicates the nominal shaft diameter or the size of the nut it is combined with. For example, AW/22X corresponds to a washer for a 22 mm shaft, while AW00X, AW01X, AW02X, AW03X and AW04X are standardized sizes for larger diameter shafts. The X suffix indicates a design variant within the series. Learn more about this nomenclature by consulting MR.

These washers are used in a wide variety of industrial applications in Argentina. They are found in gearboxes, centrifugal pumps, fans, mills, conveyors and mining equipment, among others. Their function is critical in assemblies where the bearing must remain firmly secured to the shaft, since they prevent the adjusting nut from turning and maintain the proper preload. They are also used in machine tools and in the automotive sector.

To select the correct lock washer, it is essential to verify the shaft diameter and the type of nut to be used. The tab must match the slot on the shaft or the nut to ensure effective locking. During assembly, it is recommended to place the washer with the tab oriented toward the slot and bend it firmly with a suitable tool, avoiding damage to the material. Proper lubrication and precise alignment of the assembly extend the service life of the bearing and the washer.

Regarding equivalences and interchangeability, NTN AW series lock washers can be replaced by products from other brands that follow the same dimensional standard. It is important to compare critical dimensions, such as inner diameter, outer diameter and thickness, as well as the type of tab. To ensure full compatibility, we recommend sending us the original part number or the shaft and nut measurements. At MR Accesorios Industriales we tell you the compatible alternative.
