Airtac MDJ Adjustable Cylinder MDJ16X20-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X20-20 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 MDJ16X20-20
The MDJ16X20-20 is an AirTAC adjustable-stroke multi-mount cylinder with a 16 mm bore and 20 mm base stroke. Because the square body fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side, it saves panel space in tight fixtures. As a double-acting unit it delivers about 100.5 N of theoretical push force at 0.5 MPa, and the cushion is a bumper. The -20 suffix adds a 20 mm adjustable stroke range on top of the base stroke, so the end position can be tuned without changing cylinders.
This is a genuine AirTAC part in the standard MD family, so rod rotation is not prevented; if you need a fixed-rod plate that stops the rod turning, see the MK family instead. The SKU has no S suffix, so this unit is built without a magnet; choose the -20S version if you need magnetic-switch sensing. We confirm exact dimensions and sizing help 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
Choose the 16 mm bore when your job needs roughly 100.5 N of push at 0.5 MPa in double-acting use; larger bores give more thrust but take more space. The MDJ variant is the adjustable-stroke choice: 20 mm base stroke plus a 20 mm adjustment range, with 10/20/30 mm ranges available. Keep the stroke modest - the short square cover means an over-long stroke can make the cylinder unwieldy. Decide MD (rotation allowed) versus MK (no-rotating), double versus single acting, whether you need the magnet (order the S suffix), and PT or G port threads. Side-load limits depend on the mounting case, so send us your application and we will check it against the datasheet.
Applications
Small-parts clamping
Clamp small housings or brackets in a machining fixture. The 16 mm bore's 100.5 N push and the adjustable end position let you dial in clamping travel without shimming the mount.
Jig positioning
Push workpieces against a jig stop before welding or assembly. The 6-direction body fixing lets the cylinder mount from whichever face the jig allows, and side-by-side mounting fits multiple stations.
Slide indexing
Advance a small slide one increment on a compact assembly table. The bumper cushion softens the stop, and the adjustable stroke trims the increment to match the fixture pitch.
FAQ
What does the -20 at the end of MDJ16X20-20 mean?
MDJ is the adjustable-stroke variant of the MD multi-mount cylinder. The code reads as a 16 mm bore, 20 mm base stroke and a 20 mm adjustable range added on top, so you can set the retracted or extended end position anywhere within that extra travel. Available adjustment ranges are 10, 20 or 30 mm.
How is this cylinder cushioned at the end of stroke?
The MDJ16X20-20 uses a bumper cushion rather than an air cushion. Combined with the short square cover, that means very long strokes are best avoided - if you need extended travel, confirm the stroke table and overall dimensions from the datasheet, or contact us with your layout and we will help size it.
