The NTN ALL series lock washer is a fixing component used together with a slotted nut to axially lock bearings and other elements on a shaft. Its design with an inner and outer tab prevents the nut from loosening due to vibration. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and quotes it for you on WhatsApp with the complete code.

The ALL series designation is read with the prefix ALL followed by two or three digits indicating the shaft diameter or the size of the nut it works with. For example, ALL44, ALL48, ALL56 and ALL60 correspond to increasing sizes. It is not a bearing: it is a lock washer mounted between the nut and the part to be fixed. To select it, send us the exact code shown on the drawing or on the old part.

It is used in applications where the position of a bearing or a threaded component must be secured: gearboxes, pumps, reducers, transmission equipment and machinery in general. In Argentina you will find it in industrial plant maintenance, repair shops and equipment manufacturing. It is a small but critical part: if it fails, the nut loosens and the bearing loses its fit.

To choose it well, take into account the diameter and pitch of the nut it will work with, because the inner tab must fit into the shaft groove and the outer tab must bend over one face of the nut. Check that the material and treatment are suitable for the tightening torque and vibration conditions. During assembly, bend the tab without forcing it and check that the nut is properly seated.

Lock washers are available with different nomenclatures depending on the manufacturer, but they are not always interchangeable between brands. If you have a code from another brand or an unidentified part, send us a photo or the main measurements and we will tell you the compatible equivalent. At MR Accesorios Industriales we quote the exact code or size you need.

To request a quote for your NTN ALL series lock washer, send us the complete code via WhatsApp (for example ALL44, ALL48, ALL56) or the nut and shaft measurements. We reply shortly with the quote. If you are looking for a variant you do not see, write to us with the model and we will quote it.
