Product Description

The FAG MB12 is a precision-engineered tab washer designed for securing locknuts on shafts. It is used together with FAG locknuts of the KM/KML series to ensure a firm and vibration-resistant assembly.

Its bent locking tabs engage directly with the nut and shaft keyway, preventing loosening under dynamic loads, making it ideal for:

• Bearing mounting
• Gearbox assemblies
• Motor and spindle retention
• High-vibration environments

Manufactured according to DIN 5406, the MB12 ensures compatibility with standard locknuts and provides reliable long-term holding performance.
