About the Airtac MDJ Adjustable Cylinder MDJ25X50-10
The MDJ25X50-10 is an AirTAC adjustable-stroke multi-mount cylinder, a compact square-body pneumatic cylinder that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side to save space. This double-acting 25 mm bore model delivers 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, cushioned by a bumper and running at 30-500 mm/s on air filtered to 40 um. Its magnetic-switch slots sit around the body for easy switch placement.
This is a genuine AirTAC part in the standard MD family; the MK family is the no-rotating alternative if your application must prevent rod rotation. This SKU shows no magnet, and the thread is PT as supplied (a G thread option exists). Overall dimensions vary with stroke, so 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 the 25 mm bore when you need roughly 245.4 N of push force at 0.5 MPa; smaller bores give less, larger bores more. Stay with MDJ if standard double-acting action with an adjustable stroke is what you need, and step to the MKJ no-rotating family if the rod must not turn. The MDJ adds a 10/20/30 mm adjustable range on top of the base stroke; here that range is 10 mm on a 50 mm stroke, within the 60 mm maximum for this bore. This SKU has no magnet; pick an S-suffixed code if you need magnetic switch sensing. Thread is PT by default with G available. Note the short covers on multi-mount cylinders mean the stroke should not be over-long; share side-load details with us so we can check suitability.
Applications
Small-parts clamping
A 6-way-mountable 25 mm bore clamps small parts in fixtures, with the 10 mm adjustable range set to the exact clamp position.
Jig positioning
Side-by-side mounting of square-body cylinders positions workpieces in welding or assembly jigs where panel space is tight.
Gate and stopper actuation
The bumper cushion and adjustable stroke give a controlled stop for gates and product stoppers on compact machinery.
FAQ
What does the adjustable stroke on the MDJ25X50-10 mean?
The cylinder has a 50 mm base stroke plus a 10 mm adjustable range, so the stroke can be trimmed between 50 mm and 60 mm. MDJ/MKJ cylinders accept a 10, 20 or 30 mm adjustable range; MD/MK standard cylinders do not offer this.
How is this cylinder mounted?
The square body can be fixed from six directions: front, back, left, right, top and bottom. Units also mount side by side to save space. Overall dimensions depend on the stroke, so confirm them from the datasheet, and check any side-load with us.
