Description

The SKF KML series lock nut holds bearings and similar components in place on cylindrical shafts. Its slotted body works with a lock washer to keep the nut from turning, which matters in equipment exposed to vibration. For maintenance and assembly work that calls for precise adjustment, this nut is a practical choice.
The code tells you the size. Take KML 24: the thread is M120×2. The figure after KML is not the diameter itself but a reference tied to the shaft and thread dimensions. Nuts in this series have a slim body and slots around the outside for a lock washer such as the MB type. Use the compatibility tables to match the nut to the bearing it will secure.
You will find these nuts in food processing, cement, mining, oil and power transmission operations. They appear on gearbox shafts, pumps, fans, conveyor belts and other machinery where a bearing must stay in its axial position. If the bearing shifts, the equipment can be damaged, so this locking function is not optional.
Selection starts with the thread and shaft diameter, then the bearing and lock washer. Before mounting, clean the threads, apply the correct torque and fit the lock washer so nothing works loose. A lubricated thread makes adjustment and later disassembly easier. Check alignment as well, since misalignment brings axial loads that should not be there. Doing this carefully helps the bearing last and cuts unexpected downtime.
Other brands make nuts to the same dimensional standard, including the KM series, so a cross-reference is often possible. Even so, confirm the thread and technical data before substituting one part for another. Material and surface treatment can differ between manufacturers. Our team can review compatibility with your equipment.

Frequently asked questions
- What does the number in KML 24 indicate?
- It is a size code, not a direct diameter. KML 24 uses an M120×2 thread, and each number maps to specific shaft and thread dimensions in the SKF tables. Check the compatibility table before ordering.
- How does the nut stay locked?
- A lock washer, typically MB series, fits into the slots on the nut and is bent into a notch on the shaft. That stops the nut from rotating. If you take the assembly apart, fit a new washer.
- Can a nut from another brand replace a KML nut?
- Often yes, provided it follows the same dimensions and standard, as with the KM series. Verify thread and material first. MR can advise you on compatibility.
