About the Airtac MDJ Adjustable Cylinder MDJ20X15-20
The MDJ20X15-20 is an AirTAC multi-mount cylinder: a compact square-body pneumatic cylinder that fixes from 6 directions (front, back, left, right, top and bottom), so you can place cylinders side by side and save space on the machine. This is the adjustable-stroke, double-acting version in a 20 mm bore with 15 mm base stroke and a 20 mm adjustable range for on-machine stroke tuning. At 0.5 MPa it delivers about 157.1 N of theoretical push thrust, with a bumper as the cushion.
It is a genuine AirTAC part. MD is the standard multi-mount family where rod rotation is allowed; the MK family is the no-rotating version if your application needs the rod held from turning. This SKU has no magnet (no S suffix). Dimensions and sizing are confirmed 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
Size the bore by thrust: this 20 mm bore gives about 157.1 N theoretical push at 0.5 MPa in double-acting service. Choose MD when rod rotation is acceptable and MK when it is not. Acting options are double, single push, single pull, double rod and adjustable stroke; this SKU is the adjustable-stroke double-acting type with a 20 mm adjustable range added to the 15 mm base stroke. Bore 20 covers strokes up to 60 mm, but avoid an over-long stroke on the short compact cover. This SKU has no magnet; add the S suffix if you need switch detection. Port thread is PT standard or G to order. Side-load figures come from the datasheet, so route those questions to us.
Applications
Indexing stopper
Acts as an extend-and-retract stopper that indexes parts along a small conveyor lane, with the 20 mm adjustable range setting the exact stop position.
Press-fit assist
Applies light press or seating force to small assemblies in a fixture bank where cylinders are mounted side by side in a narrow frame.
Lift-and-lower gate pin
Raises and lowers a locating pin or gate between two positions on compact automation, fixed from the top or side of the bracket as space allows.
FAQ
Does MDJ20X15-20 include a magnet?
No. This SKU has no trailing S, so it is supplied without the magnet. If you need magnetic-switch sensing, select the S version instead; the magnet is an option, not a standard feature on every model.
How is this cylinder mounted, and what should I watch on stroke?
The body fixes from 6 directions, letting cylinders sit side by side to save space. Keep the stroke modest for the compact cover, and confirm dimensions for this stroke and any allowable side-load from the datasheet or ask us.
