FAQ
What is the correct tightening procedure for a KM15 lock nut?
The KM15 should be tightened to remove clearance and then secured using a corresponding MB15 locking washer. The washer tab is bent into one of the four slots on the nut’s circumference to prevent it from loosening.
Is this nut compatible with adapter sleeves?
Yes, the KM15 lock nut is specifically designed for use with adapter sleeves (e.g., H series) and withdrawal sleeves (e.g., AH series) to mount bearings with a tapered bore.
Can I reuse a locking washer with this nut?
It is strongly recommended to use a new MB15 locking washer each time the nut is installed to ensure a secure and reliable lock. Reusing a washer can lead to metal fatigue and failure of the locking tab.
