Overview
FAG MB20-A Lock Nut (Bearing Locknut) is a precision threaded fastener that secures a bearing axially on a shaft or sleeve. Typical KM and AN series nuts clamp the inner ring, are used with adapter and withdrawal sleeves, and combine with a tab (lock) washer to prevent loosening.
The steel nut has a precision metric (or inch) thread and axial slots; the tab of a lock washer is bent into a slot to lock rotation. KM types pair with MB washers, while AN types use a self-locking feature or a separate locking part.
Key features
- Positive axial clamping of bearings on shafts and sleeves
- Secured against loosening by an MB tab washer
- Used to mount adapter and withdrawal sleeves
- Precision thread maintains accurate position and preload
Typical applications
- Self-aligning bearings on adapter sleeves
- Bearing retention on shafts and spindles
- Pump, gearbox, and motor assemblies
- Shaft-end clamping in general rotating machinery
Selection guidance
Check nut designation (e.g., KM 0, AN 08), thread pitch, shaft/thread diameter, matching washer (MB) size, and sleeve type.
