SMC's MK-Z has an allowable moment of inertia 3 times higher than the conventional MK and MK2 styles.  The overall length is the same as the conventional styles, and mounting dimensions are interchangeable with the MK series.  Auto switches can be mounted on any of the 4 surfaces with no projection of the switch.Rotary clamp cylinder w/auto switch mounting grooves, Bore sizes (mm): 12, 16
