NKE Locking Nuts are high-precision, threaded fasteners designed to securely lock bearings on shafts, preventing unwanted movement and maintaining proper bearing pre-load within machinery. Their critical role ensures reliable operation and extends bearing life in various demanding industrial applications, including agricultural machinery, mining equipment, steel mills, and hydroelectric power plants.

A locking nut is a specialized nut featuring an internal contoured surface that interfaces with a corresponding notch machined on the shaft. Tightening the nut creates a wedging action, forcing the nut and bearing inner ring firmly against the shaft shoulder, effectively preventing axial (along-the-shaft) movement of the bearing assembly. NKE Locking Nuts are manufactured to precise dimensional tolerances for optimal performance and secure locking.
