Airtac MDJ Adjustable Cylinder MDJ32X40-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X40-20 is a genuine MD multi-mount cylinder (adjustable stroke), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ32X40-20
The AirTAC MDJ32X40-20 is an adjustable-stroke, double acting multi-mount cylinder with a 32 mm bore, 40 mm base stroke and an extra 20 mm adjustable range, letting you dial in the effective stroke on the machine. The compact square body fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. Cushioning is a bumper. At 0.5 MPa this bore gives a theoretical push force of 402.1 N on air filtered to 40 um, with an operating range of 0.15-1.0 MPa (22-145 psi) and a working temperature of -20 to 70 C.
This is a genuine AirTAC part. The MD family is the standard multi-mount series, where rod rotation is allowed; the MK family adds a no-rotating plate when rotation must be prevented. This SKU carries no S suffix, so the unit is supplied WITHOUT a magnet; magnet-equipped versions use the S ending. We confirm overall dimensions and sizing for your stroke 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
Pick the 32 mm bore when you need the range's highest thrust: 402.1 N push (345.6 N pull) at 0.5 MPa, running on 0.15-1.0 MPa. This MDJ variant is double acting with a 20 mm adjustable range added to the 40 mm base stroke. If the rod must not rotate, choose the MKJ no-rotating series instead. Keep the base stroke inside the bore 32 table (up to 60 mm); the short body cover warns against over-long strokes, so check with us if in doubt. Ordering choices are magnet (the S suffix, absent here) and thread (PT default or G); side-load limits come from the datasheet.
Applications
Jig positioning
Fix the square body from any of 6 directions on a machining jig and use the 20 mm adjustable range to set an exact positioning stroke for workpiece location.
Conveyor gate control
Mount cylinders side by side along a conveyor line to drive small gates or diverters, with double acting air and bumper cushioning at each end of travel.
Slide push-and-return
Use the 402.1 N push at 0.5 MPa to advance a small slide or tray into position and retract it, tuned to the slide pitch via the adjustable stroke.
FAQ
Does MDJ32X40-20 include a magnet?
No. There is no S suffix in this SKU, so the cylinder is supplied WITHOUT a magnet, even though the body has magnetic-switch slots around it. If you need position detection, order the S version of the same model to get the built-in magnet.
How long a stroke can I set on this cylinder?
The base stroke is 40 mm plus a 20 mm adjustable range, which stays well within the bore 32 table limit of 60 mm for double acting units. The short body cover cautions against over-long strokes; confirm exact dimensions and side-load capability from the datasheet before finalising your layout.
