About the Airtac MDJ Adjustable Cylinder MDJ10X25-30
The MDJ10X25-30 is an AirTAC MD-series adjustable-stroke multi-mount cylinder, a compact square-body air cylinder that fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space on densely packed machines. Magnetic-switch slots run around the body, guide precision is high and no added lubricant is required. This double-acting model has a 10 mm bore, a 25 mm stroke and a 30 mm adjustable range, delivering a theoretical 39.3 N push at 0.5 MPa (33.0 N on the pull side) for light-duty clamping and positioning, with a bumper for cushioning.
This is a genuine AirTAC part. The MD family is the standard version where rod rotation is allowed; if the rod must not turn, choose the MK no-rotating family instead. This SKU carries no magnet (no trailing S in the code) and uses a PT thread. Dimensions vary with stroke, so we confirm overall 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
Pick the bore by thrust: at 10 mm bore this cylinder gives 39.3 N push and 33.0 N pull at 0.5 MPa in double acting; move up a bore for more force. Choose MD if rotation is acceptable, MK if it must be prevented. Acting types span double acting, single-acting push, single-acting pull, double rod and adjustable-stroke; this MDJ is double acting. The 25 mm stroke sits inside the 35 mm maximum for bore 10, and the 30 mm adjustable range extends the usable travel. This code has no trailing S, so no magnet is fitted; add S to include one. Thread is PT as standard, G optional. Avoid over-long strokes on the short cover, and check side-load limits with us.
Applications
Compact ejector or gate action
In tight machine frames, 6-way fixing lets the cylinder eject or gate small parts from the orientation that fits, with the 30 mm adjustable range setting the exact throw.
Height stopper in test rigs
Mounted top or bottom, the cylinder acts as an adjustable-height stop for small workpieces, with the bumper absorbing contact at the end of travel.
Fine positioning on assembly stations
Side-by-side mounting packs several cylinders into one station block for fine push and retract motions, with the 30 mm adjustable range dialled in per station.
FAQ
Why does this MDJ10X25-30 have no magnet?
The trailing S in the code indicates the magnet, and this SKU has no S, so it is supplied without a magnet. Magnet is optional on MD and MK multi-mount cylinders; choose the equivalent MDJ10X25-30S if you need position sensing via the switch slots in the body.
How much adjustment does the adjustable-stroke version add, and how much force does it make?
This model adds a 30 mm adjustable range on top of the 25 mm stroke. In double acting at 0.5 MPa the 10 mm bore gives a theoretical 39.3 N push and 33.0 N pull. Keep strokes short to avoid side-loading on the compact body; confirm limits from the datasheet.
