SKF AN series lock nuts are precision components used to secure bearings and other elements on threaded shafts. Their design allows firm and controlled adjustment, facilitating mounting and dismounting without damaging the parts. They are ideal for applications requiring reliable and repeatable fixing, such as industrial machinery, transmission equipment and bearing systems. At MR Accesorios Industriales we sell them as part of our mounting components line.
The designation of the AN series is interpreted as follows: the letters AN identify the type of lock nut, and the number that follows indicates the nominal shaft diameter or the thread in millimeters or inches, depending on the standard. For example, AN 15 corresponds to a nut with M75×2 thread, AN 16 to M80×2, and so on according to the code. This nomenclature allows quick selection of the appropriate nut for each application, ensuring compatibility with the bearing and shaft.
These nuts are used in a wide variety of industries in Argentina, such as metallurgy, food, petrochemical and transport. They are common in conveyor belts, pumps, fans, mills and machine tools, where bearings must be secured safely. Their design allows precise mounting and simple dismounting, which reduces maintenance times and prevents damage to components.
To select the correct nut, it is essential to verify the diameter and thread pitch of the shaft, as well as the type of bearing to be fixed. It is recommended to use an appropriate wrench and apply the specified torque to avoid deformation. Lubricating the thread facilitates mounting and protects against corrosion. In addition, it is important to ensure correct alignment to avoid undue axial loads that could affect bearing performance.
Regarding equivalences, SKF AN series lock nuts can be interchanged with products from other brands that follow the same dimensional standards, such as the KM or KML series, although thread and pitch compatibility must always be verified. It is advisable to consult the technical specifications of each manufacturer to ensure a correct fit. At MR Accesorios Industriales we have the experience to advise you on selection.

Frequently Asked Questions
- What does the AN designation mean in SKF nuts?
- The AN designation indicates that it is a standard lock nut. The number that follows is a size code (from 04, multiplied by 5 gives the thread diameter in mm; AN 15 corresponds to M75×2), not the shaft diameter. This facilitates selection according to shaft size.
- How is an SKF AN series lock nut mounted?
- It is threaded onto the shaft and tightened with an appropriate wrench to the recommended torque. It is important to lubricate the thread and verify alignment to avoid damage. It is then secured with a locking device if necessary.
- Are SKF AN series nuts interchangeable with other brands?
- Yes, as long as they comply with the same dimensional and thread standards. Brands such as KM or KML may be equivalent, but the pitch and diameter must be verified. Always consult the technical specifications before replacing.
