Airtac MDJ Adjustable Cylinder MDJ25X60-40S
The AirTAC MDJ Adjustable Cylinder MDJ25X60-40S is a genuine MD multi-mount cylinder (double rod, 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 MDJ25X60-40S
The MDJ25X60-40S is an AirTAC MDJ adjustable-stroke multi-mount cylinder, a compact square-body pneumatic cylinder that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. With a 25 mm bore and 60 mm base stroke plus an adjustable stroke range, it suits jobs where the effective stroke must be tuned on the machine. Double acting at 0.5 MPa it delivers a theoretical push thrust of 245.4 N, and the bumper cushion absorbs end-of-stroke impact.
This is a genuine AirTAC part from the MD family, the standard multi-mount series where the rod is free to rotate; if you need rotation prevented, the MK no-rotating family is the alternative. The trailing S in the code means this SKU carries a magnet for magnetic-switch detection. We confirm exact 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
Choose MD if rod rotation is acceptable; choose MK if it must be prevented. Acting type options are double acting, single push (MSD), single pull (MTD), double rod (MDD) or adjustable-stroke (MDJ, as here, which adds an adjustable range on top of the base stroke). The trailing S means a magnet is fitted; omit it if no sensing is needed. Ports are M5x0.8 on this bore, threaded PT by default or G on request. Note the short body: keep stroke within the datasheet table and avoid over-long strokes; for side-load limits, ask us.
Applications
Adjustable stopper on a conveyor line
Mounted top or side on a conveyor frame, the cylinder acts as a stroke-adjustable stopper, letting the line set stop positions precisely and package in tight side-by-side pitches.
Indexing in a rotary dial assembly machine
The adjustable stroke range lets the indexer dial in exact advance distances per station, with magnetic-switch slots around the body giving repeatable position feedback.
FAQ
What does the MDJ25X60-40S code mean?
MDJ is the adjustable-stroke version of AirTAC's MD multi-mount family, 25 is the bore in mm, 60 is the base stroke in mm and 40 is the adjustable stroke range, so the effective stroke can be tuned on the machine. The trailing S means the cylinder carries a magnet for magnetic-switch detection, and with no trailing G the ports are PT threaded (M5x0.8 on this bore).
How does the 6-direction mounting work in a tight machine layout?
The square body fixes from front, back, left, right, top and bottom, so the cylinder can be bolted on whichever face the machine frame offers, and several units can sit side by side to save space. Because the body is short, keep the stroke within the datasheet table rather than over-long; exact dimensions and side-load limits should be confirmed from the datasheet.
