Airtac MDJ Adjustable Cylinder MDJ16X40-10
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X40-10 is a genuine MD multi-mount cylinder (adjustable stroke), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ16X40-10
The AirTAC MDJ16X40-10 is an adjustable-stroke multi-mount cylinder: a compact square-body, double-acting unit that fixes from six directions and can be mounted side by side to save space on tight machine frames. The 16 mm bore gives about 100.5 N of theoretical push force at 0.5 MPa over a 40 mm stroke, and the adjustable range lets you fine-trim the effective stroke on a 10 mm window for exact part seating. The cushion is a bumper, switch slots run around the body, and the speed range is 30-500 mm/s with high guide precision and no added lubricant. This SKU is supplied without a magnet.
It is a genuine AirTAC part in the MD standard series, where rod rotation is allowed unless externally guided; the MK family carries a built-in no-rotating plate for applications that need it. Medium is air filtered to 40 um, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and temperature -20 to 70 C (0 to 150 C only with the optional high-temperature seal material). Dimensions and detailed sizing come from the datasheet; we confirm them 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 16 delivers about 100.5 N of theoretical push at 0.5 MPa (pull side lower), so move to a 20 or 25 mm bore if the job needs more force. Pick MD when rod rotation is acceptable and MK when it must be prevented. Acting choices cover double, single push (MSD/MSK), single pull (MTD/MTK), double rod (MDD/MKD) and adjustable stroke (MDJ/MKJ, like this unit, which adds a 10 mm adjustable range on top of the 40 mm stroke). Bore 16 strokes run up to 50 mm, and a short stroke relative to the cover is the stable choice, since an over-long stroke costs rigidity; side-load limits are a datasheet matter, so check with us. Magnet is ordered with the S suffix, and thread is PT (default) or G.
Applications
Pick-and-place transfer
Bolted to a lightweight gantry or slide in whichever of the six fixing directions suits the frame, the cylinder gives the short extend-and-retract moves that lift small parts out of a nest and drop them into the next station.
Indexing table push
The bumper cushion softens the end of each stroke as the cylinder advances a pawl or detent to index a small rotary table, and the adjustable range lets the stroke be trimmed to the exact detent pitch.
Conveyor stopper
Mounted under a light conveyor, it raises a stopper blade to hold cartons or trays at a pick point; several cylinders can be banked side by side where two lanes run close together.
FAQ
Does the MDJ16X40-10 include a magnet for position switches?
No. The code has no trailing S, so this cylinder is supplied without a magnet. If you need magnetic detection, order the MDJ16X40-10S version, which is identical apart from the magnet; switch slots are machined around the body either way, so a switch can be seated wherever the application needs it.
Why is the adjustable stroke useful, and what limits the mounting?
The MDJ variant adds a 10 mm adjustable range on top of the 40 mm fixed stroke, so the end position can be set precisely for part seating without redesigning the fixture. The body fixes from all six directions and can be mounted side by side to save space. Exact overall dimensions and allowable side-load come from the datasheet, so confirm both with us during design.
