About the Airtac MDJ Adjustable Cylinder MDJ32X30-20
The AirTAC MDJ is an adjustable-stroke multi-mount cylinder: a compact square-body pneumatic cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space on the machine frame. This 32 mm bore, double-acting model has a 30 mm base stroke plus a 20 mm adjustable range, giving an effective working window of 30 to 50 mm, with about 402.1 N of theoretical push force at 0.5 MPa (345.6 N on the pull side). A bumper cushions travel, magnetic-switch slots surround the body, and the guides hold high precision without added lubrication.
This is a genuine AirTAC part. In the multi-mount range the MD family is the standard version while the MK family is the no-rotating type with a plate that prevents rod rotation; MDJ is the adjustable-stroke variant of the MD family. This SKU is without the magnet (no trailing S in the code). It operates on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) across -20 to 70 C (150 C only with the optional high-temperature seal material). Overall dimensions are stroke-dependent, so we confirm them 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
The 32 mm bore is the strongest in the multi-mount series, delivering 402.1 N of theoretical push force at 0.5 MPa on this double-acting model, so it suits heavier clamping and pushing jobs. This SKU gives a 30 mm stroke with a 20 mm adjustable range - choose it when the working point may shift by up to 20 mm after installation (MDJ ranges are 10, 20 or 30 mm). Stay within the bore 32 stroke table, up to 60 mm double acting; the short covers caution against specifying an over-long stroke. This SKU has no magnet (add the trailing S for the magnetic version) and PT-threaded 1/8" ports, with a G thread available. Side-load capacity is a datasheet figure - contact us before applying lateral loads.
Applications
Conveyor diverter gate
Fix the cylinder to the conveyor side rail to kick or divert product onto a spur; the 20 mm adjustable range lets maintenance re-tune the gate throw as belt conditions change.
Lift-and-locate on assembly fixtures
Bolt the body under a weld or assembly fixture to raise a part into its locating pins; six-direction fixing means it drops into the tight space under the table and the adjustable range sets the lift height.
Pallet stopper at a conveyor station
Mount the cylinder beside the roller conveyor to stop pallets at a pick face, with the bumper absorbing the impact; the extended range covers pallets of slightly different widths.
FAQ
How does the -20 adjustable range in MDJ32X30-20 work?
MDJ cylinders combine a fixed stroke with an adjustable range of 10, 20 or 30 mm. This SKU has a 30 mm stroke plus 20 mm of adjustment, so the working stroke can be set anywhere from 30 to 50 mm. Keep the total within the bore 32 table (up to 60 mm double acting), since the short covers caution against over-long strokes.
How is the MD family different from the MK family in the multi-mount range?
Both are compact square-body cylinders that fix from six directions and mount side by side. The MD family, including this MDJ adjustable-stroke variant, is the standard type where rod rotation is not prevented. The MK family adds a no-rotating plate, brass bushing and fixed rod so the rod or plate cannot turn - choose MK when the load must not rotate.
