Airtac MKD Multi-position Clamping Cylinder MKD32X20S
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD32X20S is a genuine MK multi-mount cylinder (double rod), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKD Multi-position Clamping Cylinder MKD32X20S
The AirTAC MKD series is a compact multi-mount cylinder with a square body that fixes from six directions - front, back, left, right, top and bottom - and mounts side by side to save panel space. Magnetic-switch slots run around the body, guide precision is high and no added lubricant is needed. This MKD32X20S is the double-rod no-rotating version: a rod projects from both end faces, with a 32 mm bore and 20 mm stroke, so the same piston can drive or carry from either side - ideal for two-sided clamping, stopping and flagging jobs. Speed runs 30-500 mm/s and the cushion is a bumper. The theoretical push figure for this 32 mm double-acting bore is 402.1 N at 0.5 MPa; because the double-rod arrangement puts a rod at both faces, confirm the exact working thrust for your mounting from the datasheet. Operating pressure is 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um, proof pressure is 1.5 MPa (215 psi), and the working range is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material).
This is a genuine AirTAC part. MKD belongs to the MK no-rotating family, where a fixed rod and no-rotating plate with brass bushing stop the piston rod from turning; the standard MD family allows rotation. The trailing S on this SKU means the magnet is fitted, so magnetic switches can be seated in the body slots. The port on this 32 mm bore is 1/8" PT thread. We confirm dimensions, rod details and sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Bore sets the thrust: the facts-sheet push figure for this 32 mm double-acting bore is 402.1 N at 0.5 MPa, and because MKD carries a rod on both faces, confirm the exact working thrust for your mounting from the datasheet. Choose MKD when you need the MK no-rotating action plus a working rod at each end; standard MD allows rotation, while MK and MKD prevent it. Across the range you can pick double acting, single push (MSD/MSK), single pull (MTD/MTK), double rod (MDD/MKD) or adjustable stroke (MDJ/MKJ, adding a 10, 20 or 30 mm adjustment). Keep the stroke inside the bore-32 table, which tops out at 60 mm - the short covers mean an over-long stroke can stress the rod, so route side-load and stroke questions to us. The magnet appears only where the SKU ends in S (as it does here), and you order PT (blank) or G thread.
Applications
Two-lane gate stopper
Bolt the square body to the conveyor frame from any of its six faces: one rod lifts the stopper blade into the part path while the rod on the opposite face drives a mirror blade for the adjacent lane. The built-in magnet feeds position signals from the body slots, and the no-rotating plate keeps both blades square to the flow.
Two-sided jig clamp
In a machining or welding fixture, the compact body bolts between two fixture plates and mounts side by side with neighbouring stations. One rod clamps the bracket while the opposite rod drives a support pad on the far face, and the fixed rod plus no-rotating plate stop both pads spinning out of position.
Pick-and-place part flag
Mounted alongside a pick station, the non-rotating rod carries a flat part-present flag that must stay square to the photoelectric sensor stroke after stroke, with the magnet in the body confirming extend and retract. Side-by-side mounting lets the flag cylinder share the same row as the gripper cylinder.
FAQ
What does the S at the end of MKD32X20S mean?
The trailing S means this cylinder is built with a magnet in the piston, so magnetic switches can be seated in the slots around the body to signal position. Without the S the cylinder has no magnet. The rest of the code decodes as: MK no-rotating family, D for double rod, 32 mm bore, 20 mm stroke, and no trailing G so the port thread is PT.
Does the rod really never rotate, and what stroke can I use?
Correct - a fixed rod and no-rotating plate with brass bushing stop the piston rod turning, which is why MKD suits flags, blades and pads that must stay square. Keep the stroke within the catalogue table for the bore: for 32 mm bore, standard strokes run up to 60 mm. The short covers mean an over-long stroke can stress the rod, so stay inside the table and route side-load and dimension questions to us - we confirm them from the datasheet on request.
