The NTN AL series lock washer is an axial fixing component used together with slotted nuts to secure bearings and other elements on shafts. Its design with an outer tab and an inner tab that bends over the nut prevents it from loosening due to vibration. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, with more than 80 years of experience in the industrial sector.
The AL series designation consists of the letters AL followed by a number indicating the nominal diameter of the shaft or the thread the washer works with. For example, AL44 corresponds to a 44 mm shaft, AL52 to 52 mm, AL60 to 60 mm, and so on. The numeric suffix allows you to select the right washer according to the shaft size and the lock nut used.
These washers are used in a wide variety of industrial applications in Argentina, such as conveyor belts, mills, pumps, fans, machine tools and power transmission equipment. They are common in bearing mounting on gearbox shafts, electric motors and agricultural machinery, where secure and reliable fixing is required.
To select the correct lock washer, take into account the shaft diameter and the type of lock nut you will use. It is important that the inner tab matches the shaft groove and that the outer tab can be bent over one of the nut's notches. During assembly, make sure the washer seats correctly and that bending is done without damaging the part. Proper lubrication of the assembly also contributes to its durability.
Regarding equivalences, NTN AL series lock washers can be interchanged with products from other brands that follow the same dimensional standard. If the customer brings a code from another brand or an unidentified part, at MR Accesorios Industriales we quote it and tell you the compatible alternative. Do not hesitate to ask us about the exact size you need.
