The Ringfeder RFN 7012 locking assembly, in the 75RFN-7012 size, is a compact shaft-to-hub torque connector designed for a 75 mm shaft and a 114.7 mm locking-body diameter. It is engineered to compensate small tolerance deviations and mounting errors, helping maintain concentric torque transfer under load. For this size, the rated torque transmission is about 70 Nm (TA = 70 Nm), and the locking screws are M10 x 25 on this variant, with installation data documented in Ringfeder's technical papers. Available in standard carbon steel and stainless steel variants, RFN 7012 locking assemblies offer corrosion-resistant options when needed.
