Quick Locking Assemblies

Compact, lightweight, and cost-effective quick locking assemblies with central nut provide a fast and reliable solution for precise, backlash-free connections of position-sensitive drive components. They are suitable for both keyed and keyless shafts and ensure excellent concentricity due to their self-centering design.
Their optimized bore-to-outer-diameter ratio makes them especially suitable for use in thin-walled components and in applications with limited installation space. The low weight and low moment of inertia make them ideal for dynamic, high-speed applications.
These quick locking assemblies offer clear advantages over conventional connections such as keyways, set screws, or clamping sleeves—especially in precision applications that demand absolute freedom from backlash. With the central locking nut, the connected components can be axially and radially positioned with precision in just seconds and with minimal effort.
