About the Airtac MDJ Adjustable Cylinder MDJ16X40-30S
The MDJ16X40-30S is an AirTAC multi-mount cylinder, a compact square-body actuator that fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space. This double-acting unit has a 40 mm stroke with an added 30 mm adjustable range, letting you dial in effective travel beyond the base stroke. At 0.5 MPa the 16 mm bore delivers about 100.5 N of theoretical push, and the cushion is a bumper.
This is a genuine AirTAC part in the MD family, the standard version that allows rod rotation; the MK family is the no-rotating alternative. The magnet is present on this SKU as the trailing S shows, so switch slots around the body can be used with a compatible sensor. 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
Choose the 16 mm bore where its roughly 100.5 N theoretical push at 0.5 MPa covers your load. MD means standard rotation allowed, while MK would prevent rod rotation. Acting type here is double acting with adjustable stroke: the 40 mm base stroke plus a 30 mm adjustable range, within the bore's table. The S suffix means this cylinder carries a magnet, and the thread is PT (G is the alternative). The short covers on compact bodies caution against stretching a long stroke beyond what the design intends; ask us to check side-load against the datasheet.
Applications
Small-parts clamping
Fix the body from the top or side of a fixture and use the adjustable stroke to set exact clamp travel on small parts in a tight cell.
Jig positioning
Mount several cylinders side by side on a machining jig, adjusting each stroke to seat workpieces consistently.
Indexing fixtures
Use the 6-direction mounting to tuck the cylinder into a rotary indexing station where conventional bodies would not fit.
FAQ
What does MDJ16X40-30S decode to?
MDJ is the adjustable-stroke double-acting variant of the MD standard multi-mount family, 16 mm bore, 40 mm base stroke plus a 30 mm adjustable range, with magnet (the trailing S) and PT thread (no G suffix). Porting is M5x0.8 at this bore.
How is this cylinder mounted?
The square body fixes from 6 directions (front, back, left, right, top and bottom) and cylinders can be mounted side by side to save space. For exact overall dimensions, which vary with stroke, and allowable side-load, confirm from the datasheet or ask us.
