FAQ

What is the correct tightening procedure for a FAG KM24 lock nut?

The KM24 should be tightened using a suitable hook spanner (e.g., DIN 1810). The correct torque or angle of rotation method must be used as specified in the machine’s maintenance manual to achieve the proper bearing preload and secure locking.

Is a separate locking device required for the KM24?

Yes, KM-series lock nuts are designed to be used with a corresponding locking washer, such as an MB24 tab washer. The washer’s inner tab engages a keyway on the shaft, and one of the outer tabs is bent into a slot on the nut to prevent it from loosening.

What material is the FAG KM24 made from and what is its finish?

The FAG KM24 is manufactured from high-quality steel to ensure strength and durability. It typically has a plain or lightly oiled finish to prevent corrosion during storage and transport.
