About the Airtac MDJ Adjustable Cylinder MDJ32X30-20S
The MDJ32X30-20S is an AirTAC MDJ adjustable-stroke multi-mount cylinder: a compact square-body double-acting cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space in tight machine frames. With a 32mm bore and a 30mm stroke plus a 20mm adjustable range, it offers about 402.1 N of theoretical push thrust at 0.5 MPa (the pull side is lower), cushioned by a bumper, running 30-500 mm/s on air filtered to 40 um. Magnetic-switch slots surround the body for position detection.
This is a genuine AirTAC part in the standard MD family, where the rod is free to turn unless your tooling prevents it; the MK family is the no-rotating alternative. The SKU's trailing S means the magnet is included. Operating range is 0.15-1.0 MPa (22-145 psi) at -20 to 70 C. 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.
How to choose
Pick the 32mm bore when you need up to 402.1 N theoretical push at 0.5 MPa. MD allows rod rotation, while MK prevents it - choose MD if your tooling holds orientation. This MDJ is double acting with an adjustable stroke: 30mm base stroke plus a 20mm adjustable range on top; bore 32 double-acting strokes run up to 60mm. Trailing S means the magnet is fitted; thread is PT (G available). Because the cover is short, avoid over-long strokes, and route side-load questions to us.
Applications
Compact pick-and-place
Extend and retract a gripper to transfer small parts between stations on a compact gantry, with the cylinder fixed from the direction that fits the tight frame.
Small-parts clamping
Clamp a workpiece against a fixture during screwdriving or press-fitting, using the bumper cushion to settle the part without a hard stop.
Conveyor stopper gate
Extend a stopper blade to hold parts at a conveyor checkpoint, with cylinders mounted side by side for multi-lane lines.
Fixture indexing
Advance an indexing pin to locate a pallet at each assembly station, with the adjustable stroke fine-tuning the pin's travel.
FAQ
What does the -20 in MDJ32X30-20S mean?
It is the adjustable-stroke range in millimetres. The cylinder has a 30mm base stroke, and the MDJ design adds a 20mm adjustable range on top, so the effective stroke can be set within that extra travel. The trailing S also tells you the magnet is included; thread is PT by default (G is available).
Can I mount this cylinder from any direction?
Yes. The square multi-mount body can be fixed from six directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space. For exact dimensions, side-load limits and bore-specific details, confirm from the datasheet or ask us.
