Airtac MDJ Adjustable Cylinder MDJ16X70-30
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X70-30 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 MDJ16X70-30
AirTAC's MDJ series is an adjustable-stroke multi-mount cylinder: a compact square-body air cylinder that fixes from six directions - front, back, left, right, top and bottom - and can be mounted side by side to save space on dense machine layouts. This MDJ16X70-30 is double acting, with a 16 mm bore, a 70 mm main stroke and a 30 mm adjustable range on top of it, producing about 100.5 N of theoretical push thrust at 0.5 MPa. Cushioning is a bumper, and the magnetic-switch slots around the body support sensing with high guide precision.
This is a genuine AirTAC part. The MD family is the standard multi-mount design where rod rotation is allowed; the MK family is the separate no-rotating version with a fixed rod and plate. This SKU has no trailing S, so it is built WITHOUT a magnet - the magnet is an optional extra on the series. Overall dimensions vary with stroke, so we confirm them and any sizing questions from the AirTAC 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
Match the bore to the load: a 16 mm double-acting bore delivers about 100.5 N theoretical push at 0.5 MPa (86.4 N on the pull side). Take MD if rod rotation is fine, MK if the rod must stay fixed. Acting types: double (MD/MK), single push (MSD/MSK), single pull (MTD/MTK), double rod (MDD/MKD) and adjustable-stroke (MDJ/MKJ), where the hyphen figure sets a 10, 20 or 30 mm adjustable range on top of the main stroke. A magnet is ordered with the trailing S and omitted without it; thread is PT by default or G on request. The standard stroke table for a 16 mm bore tops out at 50 mm, so confirm this longer stroke from the datasheet before ordering; avoid over-long strokes where the covers limit travel, and route side-load limits to us.
Applications
Small-parts clamping
Clamp brackets and small housings on multi-station fixtures, using the 30 mm adjustable range to accommodate different part heights in one cylinder.
Horizontal part push-off
Push finished small parts off a nest or chute, where the compact square body fixes from the side or rear of the machine to keep the footprint small.
Height-adjustment stops
Set and re-set the height of an adjustable stop or support platen in test rigs, with the adjustable range covering several product variants.
FAQ
What is the difference between MDJ16X70-30 and a plain MD16X70 cylinder?
The MDJ adds an adjustable-stroke feature: after the 70 mm main stroke, the last 30 mm can be adjusted, letting you shorten the effective stroke to suit the fixture. A plain MD cylinder has a fixed stroke. The trailing letters matter too - no S means no magnet, and no G means the PT thread. Confirm details from the datasheet.
Are there limits I should check before ordering this 70 mm stroke?
Yes - the standard stroke table for a 16 mm multi-mount bore tops out at 50 mm, so confirm the availability and dimensions of this longer stroke from the datasheet before designing it in. Also keep in mind the covers limit over-long strokes, and allowable side-load figures come from the datasheet rather than this listing - we can confirm them for your application.
