CROSS & MORSE Moyeu de serrage RCK70 60x90

A shaft clamping element designed to give optimum concentricity, both radically and axially. Similar in design to the RCK13 but with increased length to provide improved support and reduced pressures on both shaft and hub. These units must always be installed inside the hub to ensure optimum concentricity. Axial movement of hub will occur during clamping operation.
