Airtac MDD Multi-position Double Rod Cylinder MDD25X10S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD25X10S 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 MDD25X10S
The MDD25X10S is an AirTAC multi-mount cylinder with a compact square body that can be fixed from 6 directions: front, back, left, right, top and bottom. Bodies can be mounted side by side to save space, and magnetic-switch slots run around the body. This is a double rod, double acting unit with a 25 mm bore and a 10 mm stroke, so it has a working rod on each end for short, precise movements in tight fixture layouts. At 0.5 MPa the facts sheet lists a theoretical push thrust of 245.4 N and pull thrust of 206.2 N for this bore, and the cushion is a bumper. Operating pressure is 0.15-1.0 MPa (22-145 psi), the medium is air filtered to 40 um, and the speed range is 30-500 mm/s.
This is a genuine AirTAC part in the MD family, the standard multi-mount series (rod rotation is not prevented here). The trailing S in the SKU means it comes WITH a magnet built in, so magnetic switch detection is ready. We confirm exact dimensions and sizing from the datasheet on request, since overall length changes with stroke.

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 the thrust you need: at 0.5 MPa the 25 mm bore gives 245.4 N push / 206.2 N pull (theoretical). If you need more, step up to the 32 mm bore; if less, the 20 mm bore saves space. The MDD prefix gives you a double rod, double acting cylinder with a rod on each end, useful when you need work done from both sides of the body. MD means rod rotation is allowed; pick the MK family only if the rod must not rotate. Stroke for this 25 mm double-acting bore runs up to 60 mm in the standard table, and a short 10 mm stroke keeps the body compact - very long strokes defeat the space-saving intent, so confirm the fit before oversizing. The trailing S adds the magnet; order the non-S version if you do not need switch detection. Port is M5x0.8 with PT thread as standard, or G on request. Side-load limits are not listed here - contact us and we will confirm from the datasheet.
Applications
Small-parts clamp on a milling fixture
The 25 mm bore delivers 245.4 N of push at 0.5 MPa to hold small workpieces, and the short 10 mm stroke keeps the clamp foot moving just far enough. The square body fixes from 6 directions, so it bolts onto the fixture face or side that the jig layout allows.
Gate stopper on a packaging line conveyor
Side-by-side mounting lets a row of these cylinders sit along a narrow conveyor edge to raise and lower stopper gates. The double rod gives a working rod at each end, and the bumper cushion softens each gate drop at line speed.
Indexing pin on a rotary dial table
A short-stroke double rod cylinder can lock the dial from one end and eject or locate from the other, with the body clamped top or bottom into a tight base plate. The built-in magnet (trailing S) lets a magnetic switch confirm the pin is seated.
FAQ
What does the S at the end of MDD25X10S mean?
The trailing S means this cylinder is supplied WITH a built-in magnet, so it works with magnetic switches seated in the slots around the body. The same model without the S (for example MDD25X10) is the non-magnetic version. Magnet is an option on the MD family, not a default, so order the S variant only if you need switch detection.
How many ways can I mount this cylinder?
The multi-mount square body can be fixed from 6 directions: front, back, left, right, top and bottom, and units can sit side by side to save space. Keep the stroke short for this compact format, since an over-long stroke works against the space-saving design. Exact overall dimensions for a given stroke, and any side-load limits, come from the datasheet - we will confirm them on request.
