The AW lock washer from BGL is a locking accessory placed between the KM lock nut and the adapter sleeve to prevent the nut from loosening due to vibration. Its inclined tooth design works together with the sleeve slots and the nut notches, blocking rotation. It is manufactured in carbon steel, with a stainless steel option for corrosive environments. It is a key part in bearings mounted with adapter sleeves, where secure tightening is critical.
The AW designation is read as a series of inclined-tooth lock washers, designed to be combined with KM lock nuts. Examples AW1, AW2, AW3, AW4, AW5, AW6, AW7 and AW8 cover a range of sizes that correspond to the most common adapter sleeves. The number following the letters indicates the size, not a direct measurement: each AW code fits a specific sleeve diameter and KM nut. To choose the correct washer, you must identify the sleeve and nut being used.
These washers are used in equipment where bearings are mounted on adapter sleeves: gearboxes, conveyors, mills, pumps, fans and process machinery. In Argentina, the food, cement, mining, petrochemical and material handling industries are common settings. They also appear in applications with long or hard-to-reach shafts, where the sleeve allows mounting the bearing without machining the seat. The AW washer ensures that the assembly does not lose its fit over time.
To select the AW washer, take into account the sleeve diameter and the type of KM nut. The washer is placed with its inner tooth in the sleeve slot and a tab is bent toward a notch in the nut. It is important that the tooth seats correctly and that the tab bends without cracking. In corrosive environments, the stainless steel version is recommended. Lubrication of the assembly and bearing alignment also influence the service life of the mounting. Check the fit after the first hours of operation.
The AW lock washers from BGL are interchangeable with those from other manufacturers that follow the same standard for sleeves and KM nuts. If the customer brings a code from another brand, the equivalent can be identified by the sleeve and nut size. At MR Accesorios Industriales we sell the BGL line as exclusive representative in Argentina, and we can quote the AW washer you need. Send us the code via WhatsApp and we will quote it shortly.
