SMC's MK-Z is a rotary clamp cylilnder that has a high allowable moment of inertia. The typical application for the MK-Z is to hold parts during a welding application. A short overall length means that the MK-Z series is versatile in mounting. Auto switches can be mounted on any of the 4 surfaces with no projection of the switch.
The MK-Z series part number equivalent to the old type is “MKB20-10RZ-M9NL.” When only the cylinder is to be replaced, and the current switch will continue to be used, use part numbers “MKB20-10RZ” and “BQ4-012” (auto switch mounting bracket).
Therefore, it is important to secure as a danger zone a cylindrical area with the length of the clamp arm as its radius, and the stroke plus 20 mm as its height. 123 135 155 203 363 518 65 56 Head flange (including mounting bolt) 130 150 175 209 371 578 69 58 Calculation: (Example) MKG20-10RNZ Standard calculation: MKB20-10RZ Extra weight calculation: Head flange With arm ...222 g .130
