The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X25-30 is a genuine MD multi-mount cylinder (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.
The MDJ25X25-30 is an adjustable-stroke multi-mount cylinder whose square body fixes from six directions: front, back, left, right, top and bottom. Units mount side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubricant. The double-acting 25 mm bore gives about 245.4 N theoretical push thrust at 0.5 MPa, with a bumper providing cushioning - a good fit for positioning jobs where the end of stroke must be trimmed to the application.
This is a genuine AirTAC part from the standard MD family; the MK family is the no-rotating equivalent. This SKU has no magnet, so it is best where switch detection is not needed. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s. 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.
The 25 mm bore provides about 245.4 N theoretical push thrust at 0.5 MPa; drop to a smaller bore for lighter loads. MDJ gives a 25 mm base stroke plus a 30 mm adjustable range - the widest trim window in this series - so the effective stroke is set between 25 and 55 mm. Double acting powers both directions. This code carries no magnet; choose the S version if you need switch detection. Thread is PT, with G available. Respect the bore's stroke table and short covers - avoid over-long strokes - and route side-load questions to us.
Fix the body from the top or side of a conveyor line to drive a swing gate or stopper, with the 30 mm adjustable range dialling in the throw.
Mount under a small fixture to raise and lower parts between stations, using the double-acting 25 mm bore for controlled motion in both directions.
Set the adjustable stroke to apply around 245.4 N of push at 0.5 MPa for light pressing or seating tasks on compact assemblies.
No. With no trailing S in the code, this SKU is supplied without a magnet, and magnet fitment is optional on this series rather than standard. If you need pneumatic switch detection on the body slots, order the MDJ25X25-30S variant instead.
This model has a 25 mm base stroke with a 30 mm adjustable range on top, so the effective stroke is set anywhere between them. Keep the total within the bore's stroke table - the short covers caution against over-long strokes - and confirm any side-load requirement with us before finalising the design.
