Airtac MDD Multi-position Double Rod Cylinder MDD25X30S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD25X30S is a genuine MD multi-mount cylinder (double rod), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDD Multi-position Double Rod Cylinder MDD25X30S
The MDD25X30S is an AirTAC MD-series multi-mount cylinder: a compact square body that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with other cylinders to save space. This version is double acting with a double rod, so the piston rod extends from both ends - useful for driving two stations from one cylinder or gripping a workpiece from either side. At the 25 mm bore the theoretical thrust is 245.4 N at 0.5 MPa on the full-piston side and 206.2 N on the rod side, with cushioning provided by a bumper. Running on air filtered to 40 um, it handles 0.15-1.0 MPa (22-145 psi), speeds of 30-500 mm/s and -20 to 70 C.
This is a genuine AirTAC part from the standard MD family (not the no-rotating MK family). The trailing S in the model code means this SKU carries a built-in magnet for magnetic-switch detection. Dimensions are stroke-specific, so we confirm exact sizing from the AirTAC 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
Pick the 25 mm bore when you need around 245.4 N of theoretical thrust at 0.5 MPa in a compact envelope; the double-rod MD format gives a rod on both ends, unlike a standard MD. The 30 mm stroke is comfortably within the 60 mm maximum for this bore - the short square covers favour modest strokes, so avoid pushing beyond the catalogue range. The trailing S means magnet is included on this SKU; the PT thread is the default for this bore, with G available on request. Route side-load questions to us so we can check the datasheet for your fixture.
Applications
Clamping in a machining fixture
The double rod applies clamping force from both ends of the body, letting a compact fixture hold a workpiece from two sides with one air connection point.
Vertical eject with switch feedback
The built-in magnet lets a switch confirm part ejection, while the double rod pushes the part up on one end and triggers the next station on the other.
Inline press or staking head
Side-by-side mounting stacks two MDD cylinders on a press bench, each delivering around 245 N of thrust for light staking or marking jobs.
FAQ
How do I choose between the MDD25X30 and the MDD25X30S?
Both are 25 mm bore, 30 mm stroke, double-rod multi-mount cylinders. The only difference in the code is the trailing S: MDD25X30S carries a built-in magnet for magnetic-switch position detection, while MDD25X30 is supplied without one. Pick the S version if your control system needs end-of-stroke sensing via switches.
What should I confirm from the datasheet before mounting?
The square body fixes from 6 directions and cylinders can be mounted side by side, but overall dimensions change with stroke and the allowable side load is not a published figure here - confirm both from the AirTAC datasheet. Also keep the 30 mm stroke within the catalogue table for this bore, since the short covers favour modest strokes.
