Airtac MK Series Multi-position Locking Cylinder MK32X20
The AirTAC Airtac MK Series Multi-position Locking Cylinder MK32X20 is a genuine MK multi-mount cylinder (double acting), 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 MK Series Multi-position Locking Cylinder MK32X20
The AirTAC MK32X20 is a compact square-body multi-mount cylinder that can be fixed from 6 directions - front, back, left, right, top and bottom - so several units can sit side by side to save space. Magnetic-switch slots run around the body and the guide precision is high without added lubrication. This is the double acting MK no-rotating version: a fixed rod and no-rotating plate stop the piston rod from turning, which suits jobs where the rod must stay square. The 32mm bore delivers a theoretical push force of about 402.1 N at 0.5 MPa, and the 20mm stroke covers short-reach press, clamp and stopper motions. Cushioning is a bumper.
This is a genuine AirTAC part. MK is the no-rotating multi-mount family, unlike the standard MD family. This SKU is supplied without a magnet, as shown by the code - no trailing S. Operating pressure is 0.15-1.0 MPa (22-145 psi) with air filtered to 40 um, and the medium temperature range is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material). Ports are 1/8" PT thread. We confirm exact dimensions 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
Choose the bore for your force: at 0.5 MPa this 32mm bore pushes with about 402.1 N and pulls with about 345.6 N - pick a smaller bore only if your load is well below that. MK keeps the rod from rotating; if rotation is acceptable, the MD family is the standard alternative. Acting type options across the range are double acting (MK), single push (MSK), single pull (MTK), double rod (MKD) and adjustable stroke (MKJ); this SKU is plain double acting. The 20mm stroke sits well inside the 60mm maximum for bore 32, and the short covers are why very long strokes are not practical on this compact body - ask us before specifying an over-long stroke. Side-load ratings come from the datasheet, so route that question to us. This SKU has no magnet and PT thread (G thread is the option).
Applications
Rotating-part stopper on a conveyor
A gate that drops in front of a spinning part or an off-center workpiece needs the rod to stay put. The MK32X20's no-rotating rod keeps the stop face square while the compact body fixes from 6 directions right onto the conveyor frame.
Small-parts clamp in a tight fixture
Clamping a 20mm-reach joint between fixture walls is where the square MK body shines: it bolts on from any of 6 faces and sits side by side with neighbours, pushing with about 402.1 N at 0.5 MPa on the 32mm bore.
Pick-and-place press-fit on assembly jigs
Short press or seat motions on small assemblies benefit from a rod that cannot turn as it descends. The MK32X20 mounts top-down or sideways on the jig, keeping parts square through the 20mm stroke.
FAQ
Why choose the MK32X20 over an MD-series cylinder of the same bore?
MK is the no-rotating multi-mount family: a fixed rod and no-rotating plate stop the piston rod from turning, which matters for stoppers, press fits and any job where the rod must stay square. MD is the standard family where rotation is allowed. Both share the compact square body that fixes from 6 directions and mounts side by side, so the choice comes down to whether rod rotation must be prevented.
What do I need to know before designing this cylinder into my fixture?
The 32mm bore gives a theoretical push force of about 402.1 N at 0.5 MPa and operating pressure is 0.15-1.0 MPa (22-145 psi). Overall dimensions change with the stroke, and allowable side-load values are not quoted here, so confirm both from the datasheet - we will send it on request. Also note the compact short covers mean very long strokes are not practical on this body.
