Airtac MDJ Adjustable Cylinder MDJ32X20-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X20-20S 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 MDJ32X20-20S
The MDJ32X20-20S is a genuine AirTAC adjustable-stroke multi-mount cylinder, a compact square-body actuator that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. This 32 mm bore double-acting version delivers a theoretical push thrust of 402.1 N at 0.5 MPa, with a fixed 20 mm stroke plus a 20 mm adjustable range, and cushioning by a bumper. Magnetic-switch slots run around the body and this SKU includes the magnet (trailing S), so switch detection is ready to use.
As a member of the MD family this is the standard version where rod rotation is not prevented - for a fixed, non-turning rod choose the MK family (MKJ) instead. The magnet is present only because this SKU shows the S suffix. We list genuine AirTAC parts and can confirm dimensions, overall lengths and sizing details 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
Bore sets the thrust: at 32 mm this cylinder gives 402.1 N theoretical push at 0.5 MPa, the top of the multi-mount range. MDJ is the adjustable-stroke, double-acting variant of the MD standard family; if the rod must stay rotationally fixed, pick the MKJ no-rotating equivalent instead. The fixed stroke is 20 mm with a 20 mm adjustable range on this SKU; bore 32 double-acting strokes run to 60 mm, but the short covers caution against over-long strokes, so keep applications compact and route side-load questions to us. The trailing S means the magnet is fitted for switch detection, and the port thread is PT by default or G with a trailing G - bore 32 uses a 1/8" port either way.
Applications
Small-parts clamping on fixtures
Fixed through its front or side faces on a machining fixture, the 32 mm bore clamps parts with 402.1 N push at 0.5 MPa, and the magnet lets end-of-stroke switches confirm the clamp is fully home before cutting starts.
Gate and stopper control
Side-mounted along a conveyor, the cylinder raises and lowers a stopper gate for part singulation, with switch feedback from the magnet reporting gate position and the 20 mm adjustable range absorbing setup variation.
Tray and tote eject positions
Bolted from the top face beside a storage lane, the cylinder pushes trays or totes onto a takeaway conveyor, and side-by-side mounting keeps the eject stations within a compact machine envelope.
FAQ
How do I choose between the MDJ and the no-rotating MKJ for a 32 mm application?
Both are adjustable-stroke multi-mount cylinders with the same 32 mm bore and 402.1 N theoretical push at 0.5 MPa. The MDJ allows the rod to rotate; the MKJ adds a no-rotating plate, brass bushing and fixed rod to prevent rotation. If the load would be spoiled by a turning rod, order the MKJ; otherwise the MDJ is the standard choice.
What do the ports and mounting faces of this cylinder look like in practice?
The body can be fixed from 6 directions (front, back, left, right, top and bottom) and cylinders can sit side by side to save space. Bore 32 takes a 1/8" port, PT thread by default or G thread with the trailing G option. Overall dimensions depend on stroke, so confirm them from the datasheet, and ask us before applying any side load.
