FAQ

What is the correct tightening torque for the KML34-AKN lock nut?

The correct tightening torque is not a fixed value and depends heavily on the specific application, including the bearing type, required preload, and shaft material. It is crucial to consult the machine’s technical manual or engineering specifications to determine the precise torque value needed to achieve the correct axial clamping force without damaging the bearing or shaft.

Can this KML series lock nut be reused after disassembly?

While precision lock nuts like the KML34-AKN are made from durable steel, their reuse depends on the condition of the threads and locking elements. For critical high-precision or high-speed applications, it is best practice to use a new lock nut for each assembly to guarantee performance and reliability.

What is the main difference between a KML series lock nut and a standard KM lock nut?

The KML series is a precision lock nut with a more precise thread, better perpendicularity, and an integrated locking mechanism for superior, vibration-resistant fastening. A standard KM lock nut is a more basic component requiring a separate locking washer and is used in less demanding applications.
