Airtac MDJ Adjustable Cylinder MDJ16X30-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X30-20 is a genuine MD multi-mount cylinder (adjustable stroke), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ16X30-20
The MDJ16X30-20 is a compact square-body multi-mount cylinder with a 16 mm bore, a 30 mm stroke and a further 20 mm adjustable-stroke range. Its body fixes from six directions - front, back, left, right, top and bottom - so units can be bolted side by side to save space, with magnetic-switch slots machined around the body and high guide precision that needs no added lubrication. Double acting with a bumper cushion, it gives about 100.5 N of push force at 0.5 MPa and runs at 30-500 mm/s on air filtered to 40 um.
This is a genuine AirTAC part from the MD standard family, not the no-rotating MK family, and because the code carries no S suffix it is supplied without a magnet - order the S version if you need switch detection. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and the temperature range is -20 to 70 C, extendable to 0-150 C with the optional high-temperature seal material. Overall dimensions vary with stroke, so confirm sizing from the datasheet - we can supply it 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
Bore 16 in this double acting MD family delivers 100.5 N of push force at 0.5 MPa (86.4 N on the pull side), so size the bore to your load and step up to 20, 25 or 32 mm if you need more. Choose MD if rod rotation is acceptable and MK if rotation must be prevented; acting options are double, single push, single pull, double rod or adjustable stroke. Bore 16 strokes run to 50 mm, and this MDJ version adds a 10/20/30 mm adjustable range on top of the fixed stroke - keep the stroke short, because the covers are compact and an over-long stroke is best avoided. Add the S suffix for a magnet, and choose PT (default) or G thread; ask us about side loads and datasheet sizing.
Applications
Gate and stopper on conveyors
Raising and lowering a stopper blade or gate on a light conveyor line: the 16 mm bore gives about 100.5 N at 0.5 MPa, the 20 mm adjustable range sets the gate travel, and 6-direction fixing lets the cylinder bolt straight onto the conveyor frame.
Indexing part pushers
Pushing parts into position at each index station: the square bodies mount side by side along the line to save space, and the 30 mm stroke with a 20 mm adjustable range lets each pusher be tuned to its pocket.
Ejector on small tooling
Ejecting finished pieces from a compact die or nest: the bumper cushions the eject stroke, and with no magnet fitted this version suits purely mechanical end-of-stroke detection.
FAQ
Does the MDJ16X30-20 include a magnet?
No. The code has no trailing S, so this SKU is supplied without a magnet - it is an option on MD/MK cylinders, not a standard feature. If you need magnetic-switch detection, order the MDJ16X30-20S; the body has switch slots either way.
How long can the stroke be on this bore?
For a 16 mm double acting bore, strokes run up to 50 mm, and this MDJ version adds a 10/20/30 mm adjustable range on top of the fixed stroke. Keep the stroke short for the compact covers, and confirm per-stroke dimensions and permissible side load from the datasheet, which we can provide on request.
