CROSS & MORSE Moyeu de serrage RCK16 55x85

A clamping element basically to the same design as RCK13 but with increased diameter flange to locate hub and prevent axial movements and therefore combining good concentricity with positive axial location. The increase in friction between the cones due to axial restriction results in torque reduction of approx 20% but this also means reduced surface pressures to both hub and shaft.
