About the Airtac MDJ Adjustable Cylinder MDJ25X45-10S
The AirTAC MDJ25X45-10S is an adjustable-stroke multi-mount cylinder whose compact square body fixes from 6 directions: front, back, left, right, top and bottom. Mount cylinders side by side to save panel space, with magnetic-switch slots provided around the body. This 25 mm bore double-acting version produces a theoretical push force of about 245.4 N at 0.5 MPa, with a 45 mm stroke plus a 10 mm adjustable range for fine stroke setting, and cushioning by a bumper.
This is a genuine AirTAC part in the MD standard family, where the rod is free to rotate; choose the MK family when rotation must be prevented. As the SKU shows, the trailing S means this cylinder is WITH a magnet, and the thread is PT. We confirm 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
The 25 mm bore gives a push force of about 245.4 N at 0.5 MPa on the double-acting push side. MD allows rod rotation; MK prevents it. This MDJ model pairs a 45 mm base stroke with a 10 mm adjustable range, inside the 60 mm maximum stroke for a 25 mm double-acting bore, and its short cover cautions against specifying an over-long stroke. The S suffix means the magnet is fitted for switch sensing; omit it if not required. PT thread is standard and G is available.
Applications
Indexing fixture actuation
Fix the body from any of 6 faces on an indexing dial fixture and use the 10 mm adjustment to dial in the exact advance, with the magnet confirming position.
Conveyor part push-off
Mount the square body side by side along a conveyor frame and trim the 45 mm stroke by up to 10 mm so parts are pushed off squarely every cycle.
Test-rig hold-down clamps
Bolt the cylinder to the top face of a test bench, adjust the clamp position with the 10 mm range, and sense the clamped state via the fitted magnet.
FAQ
How do I read the stroke figures in MDJ25X45-10S?
MDJ is the adjustable-stroke double-acting version of the MD cylinder. The 45 after the X is the 45 mm base stroke and the -10 is a 10 mm adjustable range on top, so the effective stroke can be trimmed to suit the application. The trailing S means the magnet is included.
Can I use this cylinder where the rod must not rotate?
No. The MD family is the standard type and the rod is free to rotate; for a fixed rod you need the MK no-rotating family. For dimensions at your chosen stroke and guidance on side-load limits, confirm from the datasheet or ask us.
