The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X50-40S 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.
The AirTAC MDJ32X50-40S is a double-acting adjustable-stroke multi-mount cylinder with a 32 mm bore and a 50 mm base stroke plus a 40 mm adjustable range shown in the code. The compact square body fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. At 0.5 MPa the bore delivers about 402.1 N theoretical push on the pressure side (about 345.6 N on the pull side), enough for clamping, stopping and positioning jobs, and the bumper cushion absorbs the end of stroke.
This is a genuine AirTAC part in the standard MD family (the MK family is the no-rotating equivalent). The trailing S in the SKU means this model comes WITH a magnet for position sensing; models without S are supplied without. We confirm exact dimensions and sizing help 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.
Choose the 32 mm bore when you need roughly 402.1 N of push at 0.5 MPa; smaller bores give proportionally less. Stay in the MD family if piston-rod rotation is acceptable and move to MK only when the rod must not turn. Acting choices are double acting (MD), single-acting push (MSD), single-acting pull (MTD), double rod (MDD) or adjustable-stroke (MDJ, this SKU). The 50 mm stroke sits within the 60 mm table limit for bore 32, and MDJ adds the adjustable range coded after the hyphen, but keep the stroke short - the covers are not designed for over-long strokes. Pick the trailing S for a built-in magnet and PT (blank) or G (trailing G) thread; bore 32 uses 1/8" ports. Side-load capacity is not listed here - confirm it with us from the datasheet.
A compact clamp under a machining or assembly jig that grips small components each cycle. The 40 mm adjustable range lets the clamp contact point be tuned without re-machining the fixture, and the bumper cushions the clamp stroke.
A vertical lift in a pick-and-place station moving small housings between chutes. Fixing the body from both top and bottom of the tight envelope, plus the built-in magnet for end-of-stroke sensing, suits short, repeatable lifts.
A stopper that rises to halt small parts or cartons on a conveyor line. The square body fixes from 6 directions so it can be bolted under the frame or between guides, and cylinders sit side by side where space is tight.
MDJ is the AirTAC multi-mount family with adjustable stroke and double acting, 32 is the bore in mm, 50 is the base stroke in mm, 40 is the adjustable range, and the trailing S means the cylinder is supplied WITH a magnet. No trailing G means PT thread; a trailing G would mean G thread. Bore 32 ports are 1/8".
The square body fixes from 6 directions (front, back, left, right, top and bottom) so it can be mounted side by side to save space. Overall dimensions vary with stroke and the adjustable range, so take them from the datasheet, and confirm allowable side-load with us before applying any lateral force.
