FAQ

What is the correct lock washer to use with an SKF KM2 lock nut?

The SKF KM2 lock nut is designed to be used with an SKF MB2 lock washer. The washer’s inner tab engages with a keyway on the shaft, and one of its outer tabs is bent into one of the four slots on the nut to prevent it from loosening.

What is the recommended tightening method for a KM2 lock nut?

For a small lock nut like the KM2, tightening is typically done using a hook spanner (e.g., SKF HN 2). There is no specific torque value; the procedure is to tighten the nut until the bearing has the correct internal clearance or preload, and then secure it by bending the lock washer tab.

Can this KM2 lock nut be reused?

Yes, SKF KM series lock nuts can generally be reused, provided the threads are in good condition and not damaged. Always inspect the nut for signs of wear or thread damage before reinstalling it. The corresponding lock washer (MB2), however, should be replaced each time.
