FAQ
What is the correct locking device for the SKF KM 23 nut?
The KM 23 lock nut is designed to be used with an MB 23 locking washer. Alternatively, for higher precision applications, MS 30/115-31/115 series locking clips can be used.
What is the proper tightening method for a KM 23 lock nut?
The KM 23 should be tightened using a hook spanner (e.g., SKF HN 21-22) that fits the four slots on its circumference. The required torque depends on the specific bearing mounting procedure, often involving measuring the reduction of radial internal clearance.
Is the M115x2 thread a standard metric coarse or fine thread?
The M115x2 designation indicates a metric fine thread. ‘M115’ is the nominal diameter in millimeters, and ‘2’ is the thread pitch in millimeters, which is finer than the standard coarse pitch for this diameter.
