The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X20-20S 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.
The MDJ10X20-20S is a genuine AirTAC adjustable-stroke multi-mount cylinder in a compact square body that can be fixed from six directions - front, back, left, right, top and bottom - allowing units to be mounted side by side to save space. This double-acting 10 mm bore model has a 20 mm base stroke with a 20 mm adjustable range and about 39.3 N of theoretical push force at 0.5 MPa, cushioned by a bumper, with magnetic-switch slots around the body.
A genuine AirTAC part from the standard MD family (not the no-rotating MK family), this SKU carries the trailing S, so it includes the magnet. Typical construction uses 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.
Select the bore for thrust - this 10 mm double-acting bore provides about 39.3 N theoretical push at 0.5 MPa. MDJ gives an adjustable stroke within the MD family; pick MK if rod rotation must be prevented. Stroke is 20 mm within the bore 10 double-acting table (up to 35 mm), plus a 20 mm adjustable range - avoid over-long strokes given the short covers. The S in this code means the magnet is included. Thread is PT standard with G available; route side-load and dimensional questions to us.
About 39.3 N of push at 0.5 MPa from the 10 mm bore secures small components, and side-by-side mounting of the compact body packs multiple clamps into one fixture.
The 20 mm base stroke with 20 mm adjustment sets precise locator positions on machining and assembly jigs, fixed from whichever of the six body faces suits the fixture.
Double-acting 20 mm travel drives short index or transfer motions, with the magnet supporting position switch detection in automated cells.
MDJ is the adjustable-stroke MD variant: it delivers the same 10 mm bore double-acting performance (about 39.3 N push at 0.5 MPa) but adds a 20 mm adjustable range on top of the 20 mm base stroke. Choose a fixed-stroke MD when the travel never needs trimming, and MK when the rod must not rotate.
Confirm the 20 mm stroke plus adjustable range suits your fixture - the short covers caution against over-long strokes on this compact body - and verify envelope dimensions and allowable side load from the datasheet before finalising the layout.
