About the Airtac MDJ Adjustable Cylinder MDJ10X20-20
The MDJ10X20-20 is a genuine AirTAC adjustable-stroke multi-mount cylinder with a compact square body that fixes from six directions - front, back, left, right, top and bottom - so cylinders mount side by side to save space. This 10 mm bore, double-acting model offers a 20 mm base stroke with a 20 mm adjustable range and about 39.3 N of theoretical push force at 0.5 MPa, suited to light clamping and indexing tasks. Cushioning is a bumper, with magnetic-switch slots around the body.
This is a genuine AirTAC part from the standard MD family, not the no-rotating MK family, and the SKU carries no magnet code, so it is supplied without a magnet. Typical materials include an aluminium-alloy body, stainless or S45C rod and NBR seals; we confirm exact 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
Size the bore by thrust: 10 mm gives about 39.3 N theoretical push at 0.5 MPa in double-acting use. MDJ is the adjustable-stroke double-acting member of the MD family; choose MK instead if the rod must not rotate. The 20 mm stroke sits inside the bore 10 double-acting table (up to 35 mm) and this J version adds a 20 mm adjustable range - keep strokes modest, since the short covers limit travel. This SKU has no S, so no magnet; add S if switch detection is needed. Thread is PT standard, G optional - send side-load questions to us.
Applications
Ejector on small assembly stations
A 10 mm double-acting bore with about 39.3 N push at 0.5 MPa ejects light parts from nests, and the compact body fixes from six directions in crowded station plates.
Gate and stopper on miniature conveyors
The 20 mm stroke plus 20 mm adjustable range raises and lowers a stopper blade precisely, with side-by-side mounting where conveyor framing space is tight.
Indexing pins in rotary dial fixtures
Adjustable stroke sets the exact index-pin engagement, and the six-way fix lets the same compact cylinder serve dial, platen and side positions.
FAQ
Does MDJ10X20-20 include a magnet?
No. The trailing S on an MDJ code indicates the magnet option, and this SKU has no S, so it is supplied without a magnet. Order the MDJ10X20-20S version if magnetic switch detection is required.
How does the 20 mm adjustable range work on this model?
The MDJ variant provides a 20 mm base stroke with an additional 20 mm adjustable range on top of it, letting you set the effective stroke within that window. Note the short covers caution against over-long strokes; confirm the exact adjustment detail from the datasheet.
