Airtac MDJ Adjustable Cylinder MDJ25X30-30S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X30-30S is a genuine MD multi-mount cylinder (adjustable stroke), 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 MDJ Adjustable Cylinder MDJ25X30-30S
The MDJ25X30-30S is an AirTAC MD-series multi-mount cylinder with an adjustable stroke: a 30 mm base stroke plus a 30 mm adjustable range, ideal where the exact end position is set on the machine rather than fixed at order time. The compact square body fixes from six directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space. This double-acting 25 mm bore version produces about 245.4 N of theoretical push force at 0.5 MPa, runs at 30-500 mm/s, operates on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and is cushioned by a bumper.
This is a genuine AirTAC part. MD is the standard multi-mount family, so the rod is free to rotate unless your fixture prevents it; only the MK family adds a no-rotating plate. The trailing S means this SKU includes the magnet for magnetic-switch sensing. We will confirm dimensions, weight and sizing details 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
Start with the bore: the 25 mm bore gives about 245.4 N of push thrust at 0.5 MPa, with less on the pull side. Take MD when rod rotation is acceptable and MK when the rod must not rotate. Acting options are double acting, single push (MSD), single pull (MTD), double rod (MDD) and this adjustable-stroke MDJ, which adds a 10, 20 or 30 mm adjustable range on top of the base stroke; double-acting strokes in this bore run up to 60 mm. Order the S suffix for the magnet, as here, and choose PT (default) or G thread. Keep the stroke within the short body cover's limits; for side-load or long-stroke questions, ask us or check the datasheet.
Applications
Pick-and-place grip station
At a small pick-and-place gripper, the magnet allows switch position feedback while the compact body mounts from the top or side of a tight tooling plate.
Sorting gate actuator
Driving a sorting gate on a conveyor line, the 6-direction fixing lets the cylinder hang from the side frame and the bumper cushions gate travel.
Machine set-up positioning
On machines that are retooled between runs, the 30 mm adjustable range lets technicians set the cylinder's end position for each new part without swapping hardware.
FAQ
How do I choose between MDJ25X30-30S and a plain MD25X30S?
Both are double-acting 25 mm multi-mount cylinders with a 30 mm stroke and magnet. The MDJ adds a 30 mm adjustable range on top of the base stroke, so pick MDJ25X30-30S when the end position must be set or changed on the machine; pick the plain MD for a fixed stroke.
What does the magnet do, and what should I check before installing?
The S suffix means this SKU carries the magnet, so magnetic switches placed in the slots around the body can signal piston position. Before installing, confirm that your stroke fits the short body cover's limits, and get stroke-specific dimensions and any side-load allowance from the datasheet.
