Airtac MDJ Adjustable Cylinder MDJ10X30-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X30-20 is a genuine MD multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ10X30-20
The AirTAC MDJ10X30-20 is an adjustable-stroke multi-mount cylinder with a 10 mm bore, a 30 mm base stroke and a 20 mm adjustable range on top. The compact square body fixes from six directions - front, back, left, right, top and bottom - so cylinders sit side by side to save space, with magnetic-switch slots around the body and high guide precision. Double acting, it pushes with a theoretical 39.3 N at 0.5 MPa (33.0 N on the pull side) at 30-500 mm/s on air filtered to 40 um, cushioned by a bumper.
This is a genuine AirTAC part from the MD standard family, distinct from the MK family whose no-rotating plate stops the rod turning. This SKU is without magnet, as the code shows. 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
This bore 10 cylinder offers a theoretical 39.3 N push at 0.5 MPa double acting, so match the bore to the load before anything else. Choose MD standard if rod rotation is acceptable, MK if not. Acting choices are double, single push, single pull, double rod and adjustable-stroke; the MDJ's -20 suffix adds a 20 mm adjustable range to the 30 mm base stroke. Bore 10 strokes top out at 35 mm, so keep base strokes within the table and avoid over-long strokes given the short cover; route side-load questions to us. This unit is listed without the magnet (order S for magnet), with PT thread by default or G to order.
Applications
Test Fixture Actuation
Actuate probes or clamps in a small test rig. The 20 mm adjustable range over the 30 mm stroke tunes engagement depth per fixture, and six-way body fixing fits crowded fixture plates.
Vertical Stopper on Feed Tracks
Raise a stopper blade to hold parts on a gravity or belt feed track. The compact body fixes top or bottom in tight track framing, and the bumper cushions the stopper's return.
Fine-Adjust Positioning
Apply controlled fine-adjust moves in assembly equipment where the stroke must be trimmed on setup. The 30 to 50 mm effective stroke range covers varied part sizes, with side-by-side mounting saving panel space.
FAQ
How much force does the MDJ10X30-20 deliver?
As a double-acting 10 mm bore cylinder, its theoretical push force is 39.3 N at 0.5 MPa, with 33.0 N on the pull side, operating at 0.15-1.0 MPa (22-145 psi). These are theoretical figures at the stated pressure; confirm application sizing from the datasheet.
Can I use a longer stroke with this cylinder?
For bore 10 the standard stroke table tops out at 35 mm, and this model's 30 mm base stroke plus 20 mm adjustable range already fills most of that window. The short cover design means over-long strokes are not advisable; for exact dimensions or special requirements, confirm from the datasheet with us.
