The FAG KM series lock nut is an axial fastening component used to secure bearings and other elements on threaded shafts. Its design with slots around the contour allows locking by means of a lock washer, which guarantees reliable fastening even in applications with vibrations. It is a key part in bearing assemblies, where it ensures the correct position and facilitates mounting and dismounting. MR Accesorios Industriales supplies this series as part of its fastening and retention line.

The designation of the KM series consists of the letters KM followed by a number indicating the size. For example, KM0, KM1, KM2, KM3, KM4, KM5, KM6 and KM7 correspond to different thread sizes and diameters. The higher the number, the larger the nut size. This nomenclature allows quick identification of the right part for each application, always verifying the dimensions of the shaft and the bearing to be secured.

These nuts are used in a wide variety of industries in Argentina, such as metalworking, food, mining and petrochemical. They are found in gearboxes, pumps, fans, conveyors and agricultural machinery, among other equipment. Their function is to keep the bearing in its axial position, preventing displacements that could damage the assembly. They are common in applications requiring precise adjustment and secure fastening.

To select the correct nut, it is essential to know the diameter and pitch of the shaft thread, as well as the type of bearing to be secured. The KM series is used with suitable lock washers, which are inserted into the slots of the nut to prevent it from loosening. During mounting, it is recommended to clean the threads, apply the specified torque and verify alignment. Proper lubrication of the thread facilitates adjustment and prevents premature wear.

As for equivalences, KM series lock nuts are interchangeable among different manufacturers that follow international standards, as long as the thread dimensions and slot design match. It is important to verify compatibility with the corresponding lock washer. When requesting a quote, it is enough to indicate the complete part number, for example KM6, to receive the correct part.

Frequently Asked Questions

What does the KM designation mean on these nuts?
The letters KM identify the lock nut series. The number that follows indicates the size: the higher the number, the larger the thread diameter. For example, KM5 is larger than KM4. This nomenclature is standard and facilitates selection according to shaft dimensions.
How is the nut locked so it does not loosen?
The KM nut has slots around its contour where a lock washer (such as the MB series) is inserted. This washer is bent over one of the slots, preventing the nut from turning. It is a simple and effective mechanical system for applications with vibrations.
Can I replace a KM nut from another brand with an FAG one?
Yes, as long as the thread dimensions and slot design match. KM nuts follow international standards, so they are interchangeable among manufacturers. Check the part number and shaft dimensions to ensure compatibility.
