Airtac MDJ Adjustable Cylinder MDJ20X35-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X35-10S is a genuine MD multi-mount cylinder (adjustable stroke), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ20X35-10S
The MDJ20X35-10S is a multi-mount cylinder that fixes from 6 directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space on densely packed machines. This adjustable-stroke MDJ variant is double acting with a 20 mm bore, a 35 mm base stroke and a 10 mm adjustable range on top, giving about 157.1 N theoretical push at 0.5 MPa. Cushioning is by bumper, and magnetic-switch slots run around the body for sensing.
This is a genuine AirTAC part from the MD family - the standard multi-mount line, where rod rotation is not prevented (select the MK family when the rod must not turn). The trailing S in the SKU shows this unit ships with a magnet. Air filtered to 40 um is the medium, operating pressure is 0.15-1.0 MPa, and exact dimensions and sizing are 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
Size the bore for thrust: the 20 mm bore delivers about 157.1 N theoretical push at 0.5 MPa in this double-acting MDJ. Choose MD when rod rotation is acceptable and MK when it must be stopped. Acting choices across the family include double acting, single-acting push (MSD), single-acting pull (MTD), double rod (MDD) and adjustable-stroke (MDJ).
This model pairs a 35 mm base stroke with a 10 mm adjustable range for fine positioning; bore 20 double-acting strokes reach up to 60 mm in the standard table. Because the cover is short, avoid over-long strokes on this compact body, and send side-load questions to us for datasheet confirmation. Trailing S means magnet included; thread is PT by default with G available as a suffix.
Applications
Jig positioning
Bolted from above a machining jig, the 10 mm adjustable range trams each stop point exactly while the 6-way fixing suits crowded fixture plates.
Pick-and-place lifting
The compact square body mounts directly under a pick head, with the magnet and body switch slots confirming grip height on each cycle.
Part hold-down on fixtures
Units mounted side by side hold down several small parts along a fixture, each with about 157.1 N of push at 0.5 MPa from the 20 mm bore.
FAQ
Why choose the MDJ over a plain MD with the same bore?
The MDJ adds an adjustable range on top of the base stroke - here 10 mm on top of 35 mm - so you can fine-tune the effective stroke to the part or fixture without swapping cylinders. Like all MD variants it is double acting, and the S suffix confirms a magnet is fitted.
Can I load the rod sideways, and where do I get mounting dimensions?
The multi-mount body fixes from 6 directions and mounts side by side to save space, but a specific allowable side-load figure is not published here - confirm it from the datasheet. Overall dimensions vary with stroke, so request the datasheet for exact mounting data.
