The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X80-20 is a genuine MD multi-mount cylinder (adjustable stroke), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact.
The MDJ32X80-20 is an adjustable-stroke multi-mount cylinder: a compact square-body air cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space. Double acting on a 32 mm bore, it delivers a theoretical 402.1 N push at 0.5 MPa (345.6 N on the pull side), with an 80 mm stroke plus a 20 mm adjustable range for setting the exact end position. Cushioning is a bumper, magnetic-switch slots are machined around the body, and operating speed is 30-500 mm/s.
This is a genuine AirTAC part. The MD family is the standard multi-mount series where the rod is free to rotate; the MK family adds a no-rotating plate if your job needs the rod held against turning. This SKU carries no position-sensing magnet (no S suffix); the magnet version is ordered with the S suffix. The thread is PT and the port on bore 32 is 1/8 inch. 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.
Choose the 32 mm bore when you need roughly 402 N of theoretical push at 0.5 MPa; smaller bores in this series deliver proportionally less. MD is the standard variant where rod rotation is allowed - pick MK if rotation must be prevented. Acting options in the family are double (MD), single push (MSD), single pull (MTD), double rod (MDD) and adjustable stroke (MDJ, this model). The 80 mm stroke is long for a compact bore-32 body, and the short-cover design cautions against pushing strokes much further - confirm side-load and buckling with us before finalising. The hyphen figure after the stroke sets the adjustable range, with standard options of 10, 20 and 30 mm. This code has no magnet; add S for the magnet version, and specify PT (default) or G thread.
Clamps small parts on machining fixtures: the 20 mm adjustable range trims the jaw travel to the part, while the square body bolts to whichever of the six faces faces the jig.
Extends a stopper or diverting gate across a conveyor lane; side-by-side mounting keeps several stopper cylinders on tight centres along the line.
Gives a compact pick-and-place head an 80 mm extend stroke with the 20 mm adjustable range used to set the exact grip or release height.
It is the adjustable stroke. MDJ is the adjustable-stroke member of the MD multi-mount family, so the cylinder covers its full 80 mm stroke plus a 20 mm adjustable range, letting you set the exact end position without spacers or shims.
The square body can be fixed from six directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space. Overall dimensions and allowable side load for this bore and stroke come from the datasheet; ask us and we will confirm them.
