Airtac MDJ Adjustable Cylinder MDJ32X40-40S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X40-40S 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.

About the Airtac MDJ Adjustable Cylinder MDJ32X40-40S
The MDJ32X40-40S is an AirTAC multi-mount cylinder with a compact square body you can fix from six directions: front, back, left, right, top and bottom. Bodies can sit side by side, so you save panel space in tight machine layouts. This model is double acting with a 32 mm bore and a 40 mm stroke that is adjustable, letting you fine-tune the effective stroke on the machine. At 0.5 MPa it delivers roughly 402.1 N of theoretical push force, enough for clamping, pushing and positioning jobs, and the cushion is a bumper.
This is a genuine AirTAC part from the MD family, the standard multi-mount series where rod rotation is allowed (the MK family is the no-rotating alternative). The trailing S in the code means this cylinder is built with a magnet for magnetic-switch detection. We can confirm dimensions and sizing from the datasheet on request before you order.

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
Choose the 32 mm bore when you need the higher thrust in the MDJ range: about 402.1 N push at 0.5 MPa. The MDJ adjustable-stroke variant is double acting, so it powers both directions with air. The 40 mm stroke sits well inside the 60 mm maximum listed for bore 32, with a 40 mm adjustable portion per the code. Pick MD for standard use or MK if the rod must not rotate. The S suffix adds the magnet, and the port thread is PT here; G is available on request. Keep the stroke short of the cover limits and check side-load figures with us from the datasheet.
Applications
Small-parts clamping
Bolted top or bottom into a compact fixture, the 32 mm bore holds workpieces with about 402.1 N of push at 0.5 MPa while the adjustable stroke dials in the grip position.
Jig positioning
Side-by-side multi-mount bodies let one jig plate carry several cylinders, each set to a different stop position using the adjustable stroke.
Sliding gate actuation
Mounted from the side of a small conveyor gate, the double-acting cylinder opens and closes the gate while the magnet S version drives a magnetic switch for gate-open feedback.
FAQ
What does the -40 suffix in MDJ32X40-40S mean?
This is an MDJ adjustable-stroke model: the 40 after X is the stroke in mm and the suffix after the hyphen is the adjustable portion. The trailing S shows the magnet is fitted, and with no G at the end the port thread is PT (1/8" on this 32 mm bore).
How many ways can I mount this cylinder?
The square body fixes from six directions: front, back, left, right, top and bottom, and units mount side by side to save space. For the exact envelope dimensions at this 40 mm stroke and any side-load limits, confirm from the datasheet.
