CENTRAL LOCK NUT RINGFEDER RFN 7075

Quick Locking Assemblies with Central Nut
Ultra-compact, lightweight, cost-efficient: High-quality locking assemblies with central nut from RINGFEDER® are the quick and easy to handle solution for frictional, absolutely backlash-free connections of position-sensitive drive components. They are suitable for use with grooved as well as grooveless shafts and have excellent concentricity properties thanks to their self-centering.

Due to the optimal ratio of bore to outside diameter, they are particularly suited for mounting on thin-walled components and in confined spaces. In addition, the low mass moment of inertia and the minimal weight ensure optimum dynamic behaviour. RINGFEDER® Quick Locking Assemblies are thus the superior alternative to conventional shaft-hub connections with keyways, setscrews, or simple tapered bushings, which do not guarantee the required freedom from backlash in precision applications. The single central locknut enables the exact axial and radial positioning of the components to be locked – in only seconds and with just a few easy steps.
