FAG KM30 Locknut

The FAG KM30 Locknut is an OEM locking nut from FAG (Schaeffler), designed to provide a secure, reusable thread engagement in precision bearing systems, and manufactured to align with FAG’s global quality programs and traceability standards for critical equipment. As a locking nut, its purpose is to prevent loosening during operation by resisting axial movement under vibration, shocks, and cyclic loading, helping maintain correct preload, axial alignment, and load distribution in rotating assemblies. The KM30 designation identifies a specific model within FAG’s catalog of locking nuts, a family designed to complement FAG bearing systems and to offer consistent fit, reliable clamping action, and predictable performance in environments where precision and reliability are essential. Selecting the KM30 locknut from FAG (Schaeffler) supports sourcing with an OEM-grade component that can simplify maintenance planning, ensure compatibility with other FAG components, and provide traceability within engineered bearing solutions. Because KM30 is part of FAG’s family of precision components, it is commonly sourced by engineers seeking consistency with other FAG parts and a documented part number for inventory and maintenance records.
