Airtac MD Multi-Position Clamping Cylinder MD20X30H
The AirTAC MD Multi-Position Clamping Cylinder MD20X30H is a genuine MD multi-mount cylinder (double acting), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MD Multi-Position Clamping Cylinder MD20X30H
The MD20X30H is an AirTAC multi-mount cylinder, a compact square-bodied pneumatic cylinder that can be fixed from six directions - front, back, left, right, top and bottom - so units mount side by side to save space on crowded machines. This double acting 20 mm bore, 30 mm stroke version pushes with a theoretical force of about 157.1 N at 0.5 MPa and cushions end of travel with an elastic bumper, suiting light clamping, locating and gating work.
It is a genuine AirTAC part from the standard MD family; the MK family looks similar but adds a no-rotating plate, fixed rod and brass bushing where rod rotation must be prevented. Magnetic-switch slots run around the body, and this SKU is listed without the built-in magnet (the S suffix adds one). Ask us to confirm exact dimensions and sizing from the datasheet.

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
Select the bore by the thrust it gives: 20 mm provides a theoretical push force of 157.1 N at 0.5 MPa, with slightly less on the pull side. MD allows rod rotation; pick MK if the load must not rotate. This model is double acting, working in both directions. The 30 mm stroke sits inside the bore 20 range (up to 60 mm), but avoid an over-long stroke on the short-cover design. Add S for a magnet, choose PT or G ports, and ask us about side-load limits.
Applications
Light part clamping
Fix the cylinder through the top or side face of a small fixture to clamp light parts during drilling, gluing or marking; the bumper-cushioned 20 mm bore is sized for these small forces.
Conveyor stopper gate
Bolt the body under or beside a conveyor line and extend a stopper blade into the product path to hold parts at a workstation, retracting between cycles.
Rotary indexing tables
Mount cylinders side by side around a compact indexing dial to drive locating pins that lock the table at each station without enlarging the footprint.
FAQ
What does the model code MD20X30H decode to?
MD is AirTAC's standard double acting multi-mount family, 20 is the bore in mm, 30 is the stroke in mm, and there is no S suffix, so this SKU is without a magnet. A trailing G would switch the ports from PT to G thread.
How many ways can I mount this cylinder?
The square body fixes from six directions - front, back, left, right, top and bottom - so cylinders mount side by side to save space. Magnetic-switch slots run around the body, and dimensions and side-load limits should be confirmed from the datasheet.
