The NTN AN series lock nut is an axial fastening component used to secure bearings and other elements to the shaft. It is used together with a lock washer to prevent loosening from vibration. It is a key part in the mounting and dismounting of bearings in industrial equipment, and MR Accesorios Industriales sells it in Buenos Aires, Argentina.
The AN series designation is read with the prefix AN followed by a number that indicates the shaft diameter or the nut size. For example, AN00, AN01, AN02 and AN03 correspond to increasing sizes, while AN/22, AN/28 and AN/32 cover larger-diameter applications. The numeric suffix makes it possible to quickly identify compatibility with the shaft and the associated bearing.
These nuts are used in industries such as food, cement, mining, oil and power transmission. In Argentina, they are common in pumps, gearboxes, fans, conveyor belts and machine tools. Their function is to secure the axial position of the bearing, making mounting and preventive maintenance easier.
To select the correct nut, take into account the shaft diameter, the thread pitch and compatibility with the lock washer. Mounting must be done with the appropriate washer and the recommended lubrication to prevent seizing. Alignment and tightening torque are critical to ensure bearing service life and prevent premature failures.
NTN AN nuts can be interchanged with those of other brands that follow the same designation standard, such as SKF, FAG or NSK, as long as the dimensions and pitch match. If you have the part number from another brand, we can tell you the compatible equivalent. MR Accesorios Industriales advises you so that the part is the right one.
