Airtac MDJ Adjustable Cylinder MDJ25X35-30
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X35-30 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.

About the Airtac MDJ Adjustable Cylinder MDJ25X35-30
The MDJ25X35-30 is an adjustable-stroke multi-mount cylinder with a compact square body that fixes from 6 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. With a 25 mm bore, a 35 mm stroke and a 30 mm adjustable range on top, this double-acting unit offers a theoretical push thrust of 245.4 N at 0.5 MPa (operating pressure 0.15-1.0 MPa / 22-145 psi) and cushions with a bumper, giving you a wide tuning window for clamping and ejecting tasks.
This is a genuine AirTAC part from the MD standard family, not the MK no-rotating family, and this SKU is without a magnet (no S suffix), though magnet versions exist in the series. Porting is M5x0.8 with a PT thread as coded. Because overall dimensions change with stroke and adjustment, 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 provides a theoretical push thrust of 245.4 N at 0.5 MPa; step up or down a bore size if your load needs more or less. The MD family permits rod rotation, whereas MK prevents it, and MDJ is the adjustable-stroke option within MD. Acting is double acting at 30-500 mm/s. The 35 mm stroke is within the 60 mm maximum listed for a 25 mm bore double-acting unit, and the 30 mm adjustable range is added on top, so effective stroke is set on site rather than fixed at order time. Respect the short cover of the compact body and avoid over-long strokes; for side-load limits, consult the datasheet through us. This SKU has no magnet (no S suffix); select an S version if you need switch sensing. Thread is PT as coded, with G selectable.
Applications
Press-fit and ejection
Apply the 25 mm bore's 245.4 N push at 0.5 MPa to eject or lightly press small components, with the 30 mm adjustable range covering part-to-part variation.
Indexing fixtures
Mount units side by side along an indexing fixture, fixing each square body from whichever of the 6 directions suits the frame, and tune each stroke independently.
Machine gate actuation
Drive small interlock gates or diverters where the 35 mm stroke plus 30 mm adjustment lets you match travel to the gate opening during commissioning.
FAQ
How much stroke adjustment does the MDJ25X35-30 give me?
The base stroke is 35 mm, and the MDJ adjustable-stroke design adds a 30 mm adjustable range on top, so you can set the effective stroke anywhere across that window after installation. For a 25 mm bore double-acting unit the stroke table goes up to 60 mm, so this configuration stays comfortably within range.
Where do I find the exact dimensions of this cylinder?
Overall dimensions of a multi-mount cylinder depend on the stroke and adjustment, so they are not quoted as a single spec here. We confirm the full dimensional drawing and sizing data from the AirTAC datasheet on request.
