Airtac MDJ Adjustable Cylinder MDJ20X70-10
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X70-10 is a genuine MD multi-mount cylinder (adjustable stroke), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ20X70-10
The MDJ20X70-10 is an AirTAC multi-mount cylinder with an adjustable stroke: a compact square body you can fix from 6 directions (front, back, left, right, top or bottom) and mount side by side to save space. This unit is double acting with a 20 mm bore, a 70 mm base stroke and a 10 mm adjustable range, giving about 157.1 N of theoretical push at 0.5 MPa. Cushioning is a bumper, and magnetic-switch slots run around the body. Speed range for double acting is 30-500 mm/s.
This is a genuine AirTAC part in the standard MD family; the MK family adds a no-rotating plate for jobs where the rod must not turn. As coded, this SKU is without a magnet (the S suffix marks a magnet-equipped version). It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), from -20 to 70 C (up to 150 C only with the optional high-temperature seal material). 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
Pick the 20 mm bore when you need about 157.1 N of push at 0.5 MPa (the pull side gives less). Choose MD when rod rotation is allowed, or MK when it must be prevented. Acting types are double acting, single push (MSD), single pull (MTD), double rod (MDD) and adjustable stroke (MDJ, this model). Strokes stay short on this compact body, so check an over-long stroke against the datasheet before committing; the MDJ adds a 10, 20 or 30 mm adjustable range on top of the base stroke. Select the magnet with the S suffix and the thread as PT or G.
Applications
Small-parts clamping
Bolt the square body under a jig table and use the adjustable range to set exact clamp travel on small brackets or housings.
Gate and stopper actuation
Fix the body from the top or side of a line to raise a stopper plate; the bumper cushions each part stop.
Jig positioning
Mount several units side by side in a fixture to advance pins or locators in sequence without extra bracket space.
FAQ
What does the -10 in MDJ20X70-10 mean?
It is the adjustable stroke: the piston stroke is 70 mm and you can set the effective stroke within an extra 10 mm range on top. MDJ cylinders are also offered with 20 or 30 mm adjustable ranges, and the S suffix adds a magnet.
How can I mount this cylinder?
The square body fixes from 6 directions (front, back, left, right, top or bottom), and units sit side by side to save space, with magnetic-switch slots around the body. Because overall dimensions change with stroke, confirm them from the datasheet.
