About the Airtac MDJ Adjustable Cylinder MDJ25X50-30
The AirTAC MDJ25X50-30 is an adjustable-stroke multi-mount cylinder, a compact square-body pneumatic cylinder that fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space. This double-acting 25 mm bore model has a 50 mm base stroke plus a 30 mm adjustable range for tuning the effective stroke in the fixture. At 0.5 MPa it delivers a theoretical push force of about 245.4 N, with a lower pull-side figure, and the cushion is a bumper.
This is a genuine AirTAC part. The MD family is the standard multi-mount design; the MK family is the separate no-rotating version that stops the rod turning. This SKU carries no magnet (no trailing S), so it is supplied without magnetic switch detection. We confirm exact dimensions and sizing help 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 sets the thrust: this 25 mm bore gives about 245.4 N theoretical push at 0.5 MPa double acting. Choose MD for standard mounting where rod rotation is acceptable, or MK if the rod must not rotate. Acting types include double acting, single push (MSD), single pull (MTD), double rod (MDD) and adjustable stroke (MDJ). Keep the base stroke within the bore 25 table, up to 60 mm; the short covers mean an over-long stroke works against the compact layout. This SKU has no magnet; add the trailing S if you need magnetic switch detection. Thread is PT by default or G on request.
Applications
Jig positioning in welding and assembly fixtures
Position and hold workpieces in a jig. The 30 mm adjustable range lets you dial in the stop position, and 6-direction fixing suits densely packed fixture plates.
Compact press or staking station
Apply light pressing or staking force to small parts. The 245.4 N push at 0.5 MPa and bumper cushion suit short, controlled compress moves.
Indexing and part ejection on automation lines
Eject or index parts between stations where cylinders must sit side by side in a tight machine envelope.
FAQ
Does MDJ25X50-30 include a magnet for switch detection?
No. The absence of the trailing S means this SKU is supplied without a magnet. If you need magnetic switch detection, order the MDJ25X50-30S variant, which is the same cylinder with the magnet fitted.
Which directions can I mount this cylinder from?
The multi-mount body fixes from 6 directions: front, back, left, right, top and bottom. That, plus the magnetic-switch slots around the body and the ability to place cylinders side by side, is what makes it space-saving. For side-load limits and exact mounting dimensions, confirm from the datasheet with us.
