MK-Z Swing Clamp Cylinder, Standard w/Auto Switch Mounting Grooves
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.
- Rotary clamp cylinder w/auto switch mounting grooves
- Bore sizes (mm): 12, 16, 20, 25, 32, 40, 50, 63
- Standard stroke (mm): 10, 20, 30, 50 (depending on bore size)
- Clockwise or counterclockwise rotary direction
- Auto switch capable

Operating pressure (MPa)
Unit: N
Note 1) Refer to Rotary Angle figure.
Note 2) Direction of rotation viewed from the rod end when the piston rod is retracting
Note 3) Clamp force at 0.5 MPa
Note 4) When using the cylinder within a pressure range from 0.61 to 1 MPa, please use –X2071.
Note 5) Be sure to install a speed controller to the cylinder, and adjust the cylinder speed to make it within the
range from 50 to 200 mm/s. To adjust the speed, start with the needle in the completely closed position,
and then adjust it by opening gradually.
