Airtac MDD Multi-position Double Rod Cylinder MDD25X50S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD25X50S 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 MDD25X50S
The MDD25X50S is a genuine AirTAC double-rod multi-mount cylinder with a 25 mm bore and 50 mm stroke. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space, with magnetic-switch slots machined around the body. Running on filtered air at 0.15-1.0 MPa (22-145 psi), this double-acting bore delivers a theoretical 245.4 N on the push side and 206.2 N on the rod side at 0.5 MPa, with a bumper for cushioning. Speed range is 30-500 mm/s.
This is a genuine AirTAC part from the MD family: a standard multi-mount cylinder with a rod on each end, so the same working force is available from either side of the piston. The S suffix means this SKU is built with a magnet for position sensing in the body's switch slots. Media is air filtered to 40 um; operating temperature is -20 to 70 C, extendable to 0-150 C only with the optional high-temperature seal material. We confirm 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
Bore 25 gives you a theoretical 245.4 N push at 0.5 MPa (206.2 N on the rod side) - size the bore from the force your job needs. Choose MDD double rod when you need a working rod on both ends; MD if only one side works, MK if the rod must not rotate. Stroke for this bore runs up to 60 mm in the table; 50 mm suits mid-travel moves, but avoid over-long strokes - the compact covers are not designed for them, and side-load limits should be confirmed with us. This code carries the magnet (S), so end positions can be sensed in the body's switch slots. Ports are M5x0.8, PT thread standard with G available.
Applications
Fixture clamping and sensing
Clamp parts in a machining fixture from either rod end while the built-in magnet signals clamp and unclamp through the body's switch slots - the side-by-side mount keeps multiple clamps tight together on crowded fixtures.
Eject and reject station
Eject off-spec parts from a line at a defined 50 mm stroke. The bumper cushions each cycle, the magnet confirms the rod has returned, and top or bottom fixing drops the unit straight into the frame.
Small-parts press fit
Press pins or bushings into small assemblies with the bore 25 rod-side force at 0.5 MPa, sensing completion with the magnet. The compact body sits between other components thanks to 6-direction fixing.
FAQ
What does the S at the end of MDD25X50S mean?
The trailing S means this cylinder is built with a magnet, so magnetic switches can be clamped into the slots around the body to signal rod position. Without the S the cylinder works identically but carries no magnet. Thread is PT (M5x0.8 on this bore) unless a G suffix is specified.
How do I mount this cylinder in a tight machine?
The square body fixes from 6 directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space. Dimensions vary with stroke and mounting style, so pull the exact figures from the datasheet or ask us to confirm them before cutting the mounting plate.
