FAQ

Question? What is the correct tightening procedure for a KM15 lock nut?

Answer: The KM15 should be tightened using a suitable hook spanner (e.g., DIN 1810). For precise bearing clearance, it should be tightened to a specific torque or using the angle of rotation method, as specified in the bearing mounting instructions. It is then secured by bending a tab of the corresponding MB15 lock washer into one of the nut's slots.

Question? What locking device is compatible with the KM15?

Answer: The FAG KM15 lock nut is designed to be used with an MB15 lock washer. The washer has an inner tab that locates in a keyway on the shaft and an outer tab that is bent into a slot on the nut to prevent rotation.

Question? Can this nut be reused after disassembly?

Answer: Yes, in most cases the lock nut can be reused, provided the threads are undamaged and it has not been over-torqued or deformed. However, the lock washer (MB15) is a single-use item and should always be replaced upon reassembly.
