About the Airtac MDJ Adjustable Cylinder MDJ25X50-20
The MDJ25X50-20 is an AirTAC adjustable-stroke multi-mount cylinder: a compact square-body cylinder you can fix from six directions (front, back, left, right, top and bottom) and install side by side to save space. This double-acting 25 mm bore unit gives 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 20 mm adjustable stroke range, a bumper cushion, and 30-500 mm/s speed on air filtered to 40 um. Magnetic-switch slots are machined around the body.
This is a genuine AirTAC part in the standard MD family; the MK family is the no-rotating option when the rod must not turn. This SKU shows no magnet, and the thread is PT with a G option available. Because overall dimensions change with stroke, 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
Select the 25 mm bore for tasks needing about 245.4 N of push thrust at 0.5 MPa; step up or down a bore if your force requirement differs. MDJ covers double-acting operation with an adjustable stroke, while MKJ prevents rod rotation if that is required. This variant carries a 20 mm adjustable range on a 50 mm base stroke, letting you set anything from 50 mm to 70 mm, with the bore's stroke table topping out at 60 mm. There is no magnet in this code; choose an S suffix if you need switch sensing. PT thread is standard, G is optional. Keep the stroke proportionate to the short multi-mount covers and check side-load cases with us.
Applications
Height stop and locating
A top- or bottom-mounted 25 mm bore cylinder sets workpiece height at a locating stop, with the 20 mm adjustable range covering several product sizes.
Test and assembly fixture actuation
Six-direction fixing lets engineers mount the cylinder exactly where a fixture needs a push, without redesigning the mounting plate.
Machine setup adjustment
The 20 mm adjustable stroke lets technicians fine-tune actuator travel during machine setup and changeovers, with the bumper cushioning each stop.
FAQ
How do I choose between a 10, 20 or 30 mm adjustable range on an MDJ cylinder?
Match the range to how much stroke variation your application needs. The MDJ25X50-20 gives 50 mm base stroke plus 20 mm of adjustment, so it can run anywhere from 50 mm to 70 mm. If you need finer or smaller trimming, the 10 mm range version is a close sibling.
What pressure and temperature can this cylinder handle?
Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), on air filtered to 40 um. The standard temperature range is -20 to 70 C; 0 to 150 C is possible only with the optional high-temperature seal material. Stroke length is limited by the short covers, so confirm details from the datasheet.
