Airtac MDJ Adjustable Cylinder MDJ16X25-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X25-20S 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 MDJ16X25-20S
The AirTAC MDJ multi-mount cylinder is a compact square-body pneumatic cylinder that can be fixed from 6 directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MDJ16X25-20S is a double-acting adjustable-stroke model with a 16 mm bore and 25 mm stroke, plus an extra 20 mm of stroke adjustment at the end of travel. At 0.5 MPa the 16 mm bore delivers a theoretical push force of 100.5 N, and cushioning is provided by a bumper.
This is a genuine AirTAC part in the standard MD family, so the piston rod is free to turn - the no-rotating function belongs to the separate MK family. Magnetic-switch slots are arranged around the body, and this SKU includes the magnet (shown by the trailing S). We confirm dimensions, weights and sizing details 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 bore for thrust: this 16 mm bore gives 100.5 N theoretical push at 0.5 MPa double acting, with the pull side lower. MD is the standard family where rod rotation is allowed; pick MK if rotation must be prevented. Acting options include double, single push, single pull, double rod and adjustable-stroke - this model is double acting with a 25 mm stroke, inside the bore 16 double-acting limit of 50 mm, and a 20 mm adjustable range on top. Short covers keep the body compact, so avoid specifying an over-long stroke; confirm side-load limits with us. Select the magnet with the S suffix and the port thread PT (default) or G.
Applications
Test-station part clamp
The magnet enables position-detecting switches on a compact 16 mm clamp, so lab and test stations can confirm grip before the cycle continues.
Workbench jig clamping
Fixed from the top, side or face on a bench jig, the adjustable 20 mm range sets exact clamp travel for repeatable small-part holding.
Guided tote stopper in tight cells
Side-by-side mounting lets several stopper cylinders sit in one row, with bumper cushioning easing the stop of moving totes or carriers.
FAQ
How do I read the code MDJ16X25-20S?
MDJ is the AirTAC adjustable-stroke version of the standard MD multi-mount family (double acting). The 16 is the bore in mm, X25 is the 25 mm base stroke, -20 adds a 20 mm adjustable range, and the trailing S shows the magnet is included. The port thread is PT by default; add G when ordering for G threading.
Can the cylinder be mounted from any face?
Yes. As a multi-mount cylinder it can be fixed from 6 directions - front, back, left, right, top and bottom - and units can be mounted side by side to save space. Exact mounting dimensions and allowable side load depend on the application, so confirm them from the datasheet before designing the fixture.
