Airtac MDJ Adjustable Cylinder MDJ10X30-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X30-20S is a genuine MD multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ10X30-20S
The MDJ10X30-20S is an AirTAC MDJ adjustable-stroke multi-mount cylinder with a compact square body that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with neighbours to save space. Being double acting with a 10 mm bore and 30 mm stroke, it delivers roughly 39.3 N theoretical push and 33.0 N pull at 0.5 MPa - useful for light clamping and positioning - and the adjustable stroke adds a further 20 mm of tunable travel. Cushioning is a bumper, and the media is air filtered to 40 um, with operation from -20 to 70 C (0 to 150 C only with the optional high-temperature seal material).
This is a genuine AirTAC part from the MD family, so the rod is free to rotate - if you need rotation prevented, look at the MK no-rotating family instead. The trailing S means this SKU includes the magnet for switch detection. We are happy to 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
Choose the bore for thrust: at 0.5 MPa this 10 mm bore pushes about 39.3 N (pull about 33.0 N) - step up or down in bore if you need more or less force. MD gives standard double-acting motion; MK would stop rod rotation. The base stroke of 30 mm sits within the bore-10 double-acting table (up to 35 mm), and the J suffix adds a 20 mm adjustable range on top. The S means with magnet; order without if you do not need switch detection. The default port thread is PT - a G thread is available on request. Keep the stroke modest, since the short cover tolerates only limited travel, and route any side-load question to us.
Applications
Small-parts clamping
Bolted through the top or side of a fixture plate, the adjustable stroke lets a technician dial in exactly how far the 10 mm bore rod closes on a small plastic or metal part before clamping it.
Jig positioning
Mounted side by side on a drill or assembly jig, several MDJ10X30-20S cylinders occupy minimal width, with the 20 mm adjustment used to fine-tune each stop position without shimming.
Slide gate actuation
Fixed from the front or bottom of a small chute, the cylinder pushes a gate across the flow path, with the bumper cushioning the gate at the end of its 30 mm travel.
FAQ
What does the code MDJ10X30-20S actually specify?
MDJ is the adjustable-stroke double-acting version of the MD multi-mount family; 10 is the bore in mm; 30 is the base stroke; 20 is the extra adjustable range on top; the trailing S means the unit includes a magnet, and the absent thread letter means PT ports (M5x0.8 on this bore).
How many ways can I mount this cylinder, and how far can the stroke go?
The square body can be fixed from 6 directions: front, back, left, right, top and bottom, and units can sit side by side to save space. For this bore the base stroke tops out around 35 mm, and the MDJ adds the 20 mm adjustable range; confirm exact dimensions from the datasheet before laying out your mounting.
