RINGFEDER CENTRAL LOCK NUT RFN 7085

DESCRIPTION: 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.
