About the Airtac MDJ Adjustable Cylinder MDJ25X50-10S
The MDJ25X50-10S is an AirTAC adjustable-stroke multi-mount cylinder, a compact square-body pneumatic cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side to save space. This double-acting 25 mm bore model produces a theoretical push force of 245.4 N at 0.5 MPa (206.2 N on the pull side) with a 50 mm stroke plus a 10 mm adjustable stroke range, a bumper cushion, and 30-500 mm/s speed on air filtered to 40 um.
This is a genuine AirTAC part in the standard MD family; choose the MKJ no-rotating family when rod rotation must be prevented. The trailing S in this SKU means the cylinder carries a magnet for magnetic switch sensing. The thread is PT as supplied, with G available. Dimensions vary with stroke, so we confirm exact 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
The 25 mm bore is the choice around 245.4 N of push thrust at 0.5 MPa; compare bores if your force need differs. MDJ suits double-acting duty with a tunable stroke, while MKJ is the no-rotating counterpart. The adjustable range here is 10 mm on a 50 mm base stroke, inside the 60 mm stroke limit for this bore, and ranges of 10, 20 or 30 mm can be specified. The S in the code means magnet included; drop it for an unmagnetized cylinder. Thread is PT standard with G optional. Keep the stroke within the short-cover design of the multi-mount body, and route any side-load questions to us before you order.
Applications
Pick-and-place part grip
A compact 25 mm bore gripper or clamp with magnet-sensor feedback holds and releases small parts in tight pick-and-place stations.
Slide and transfer motion
Side-by-side mounted cylinders drive short horizontal slides, with the 10 mm adjustable range dialing in the end position.
Indexing fixtures
The adjustable stroke sets repeatable index positions on rotary or linear indexing fixtures where the body must fit from any face.
FAQ
What does the S in MDJ25X50-10S indicate?
The trailing S means this cylinder is supplied with a magnet in the piston, so magnetic switches can be seated in the slots around the body. The same code without the S is the unmagnetized version; magnet is an option, not a standard feature.
How does the 10 mm adjustable range work here?
On top of the fixed 50 mm stroke, the MDJ design gives a 10 mm adjustable stroke, so the effective stroke can be set anywhere from 50 mm up to 60 mm. Multi-mount cylinders have short covers, so avoid strokes beyond the bore's rated maximum and confirm dimensions from the datasheet.
