Airtac MDJ Adjustable Cylinder MDJ10X30-30S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X30-30S 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 MDJ10X30-30S
The MDJ10X30-30S is an AirTAC MDJ adjustable-stroke multi-mount cylinder with a compact square body that can be fixed from 6 directions and installed side by side to save space. Double acting, with a 10 mm bore and 30 mm stroke, it produces about 39.3 N theoretical push and 33.0 N pull at 0.5 MPa - enough for light clamping, lifting and indexing - while the adjustable stroke contributes a further 30 mm of tunable travel. Cushioning is a bumper; the medium is air filtered to 40 um; the range is -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 standard family, so the rod rotates freely; pick the MK no-rotating family when it must not. The trailing S confirms this SKU includes the magnet. Dimensions and sizing can be 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
Match the bore to the force you need: at 0.5 MPa the 10 mm bore gives about 39.3 N push (33.0 N pull), so go larger if your load demands more. MD allows rod rotation; MK prevents it. The 30 mm stroke fits the bore-10 double-acting table (up to 35 mm) and the MDJ adds the maximum 30 mm adjustable range. The S suffix means the magnet is included, which pairs with the switch slots machined around the body. Ports are M5x0.8 with PT thread standard and G optional. Keep strokes conservative given the short cover, and direct any side-load query to us.
Applications
Indexing on a rotary table
Fixed to the base of an indexing fixture, the cylinder advances a pawl or pin to index the table, and the magnet lets a nearby switch confirm each completed stroke before the cycle continues.
Press-fit light components
Top-mounted over a small assembly nest, the unit presses bearings or clips into plastic housings, with the 30 mm adjustment tuned so the press depth is repeatable.
Sorting gate on tote lines
Side-mounted along a tote sorting lane, the cylinder kicks totes into a divert lane, the magnet feeding a position signal back to the PLC at each stroke end.
FAQ
Does the S in MDJ10X30-30S matter, and how does it work?
Yes: the trailing S means this SKU is supplied with a built-in magnet, so magnetic switches seated in the slots around the square body can detect piston position. Without the S the cylinder is supplied magnet-free, and switch sensing would not work. The magnet is an option, never a standard fitting on every unit.
Where can the MDJ10X30-30S be mounted and what are its limits?
Fix it from any of 6 directions - front, back, left, right, top or bottom - and place units side by side on close centres to save space. Keep the stroke within the bore table rather than relying on the short cover for long travel, and confirm the allowable side load and exact dimensions from the datasheet before finalising the design.
