About the Airtac MDJ Adjustable Cylinder MDJ32X35-20S
A compact multi-mount cylinder with a square body that fixes from six directions - front, back, left, right, top and bottom - and mounts side by side to save space where conventional cylinders will not fit. This MDJ variant is the adjustable-stroke, double acting member of the MD family, with a 32 mm bore, a 35 mm base stroke and a 20 mm adjustable range for setting the working stroke on the machine. At 0.5 MPa the bore produces a theoretical push thrust of 402.1 N, and the cushion is a bumper.
It is a genuine AirTAC part: MD is the standard family, while MK is the no-rotating counterpart. The SKU carries the magnet option, so the magnetic-switch slots around the body are ready for switches. Overall dimensions depend on the stroke and come from the datasheet - we confirm sizing 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 by thrust: 32 mm gives a theoretical 402.1 N push and 345.6 N pull at 0.5 MPa, double acting. MD lets the rod rotate; choose MK when rotation must be prevented. This model is double acting with adjustable stroke - alternatives include single acting push (MSD), single acting pull (MTD) and double rod (MDD). The 35 mm stroke is within the bore 32 table (up to 60 mm), and the 20 mm adjustable range is one of the offered 10/20/30 options. The trailing S specifies the magnet; PT is the port thread, with G as an option. Watch the short-cover limit against over-long strokes, and send side-load questions to us.
Applications
Fixture clamping with stroke trim
Fix the cylinder to the bottom or side of a machining fixture and clamp parts between operations. The 20 mm adjustable range absorbs fixture tolerance so the clamp lands correctly on every part.
Gate control on a parts diverter
Mount the cylinder to the side of a diverter gate to swing or push parts down the required lane. The square body fixes from six directions, so it bolts on wherever frame space allows.
Indexing a rotary dial table
Use the cylinder to advance parts into position at each index station. Side-by-side mounting keeps multiple units on a dense dial, and the 20 mm adjustable range sets the index depth per product.
FAQ
Why pick MDJ32X35-20S over a fixed-stroke MD32?
The MDJ adds a 20 mm adjustable range on top of the 35 mm base stroke, so you can set the effective stroke at installation instead of re-ordering cylinders for each stroke length. Otherwise it is the same 32 mm bore, double acting MD platform, with the magnet included as shown by the S suffix.
Can I mount this cylinder in any orientation?
Yes - the multi-mount square body fixes from six directions: front, back, left, right, top and bottom. Overall dimensions vary with the stroke, so confirm them from the datasheet, and check any side-load on the rod with us before mounting the load off-axis.
