This document provides technical specifications for the Ringfeder RfN 7012 Locking Assembly. It includes a comprehensive table of dimensions corresponding to various shaft diameters (d) and hub bores (D), listing maximum transmissible torques and axial forces along with required locking screw sizes.
The assembly is designed as an industry standard for applications requiring high load transmission, such as chain wheels, pulleys, and gear mechanisms. Key characteristics include a compact design suitable for tight spaces, tolerance compensation, resistance to contamination due to surface pressure during tightening, and wear-free operation without moving parts on the shaft or hub.

Yes, up to four can be arranged in series where transmissible torques and axial forces add up.
Yes, surface pressure generated during tightening prevents contaminants from reaching functional surfaces.
No, it works without moving parts on the shaft and hub to avoid wear.
