CROSS & MORSE Moyeu de serrage RCK80 65x84

A shaft clamping element designed to fit into small diameter hubs being particularly suited to light duty, light torque applications. A spacer ring prevents axial movement during clamping and the design ensures good levels of concentricity. For correct operation of these units the hub diameter should not be less than the flange diameter, even though with many materials stress limits would allow selection of smaller hub diameters.
