Airtac MDD Multi-position Double Rod Cylinder MDD32X40S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD32X40S is a genuine MD multi-mount cylinder (double rod), 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 MDD Multi-position Double Rod Cylinder MDD32X40S
The MDD32X40S is an AirTAC multi-mount cylinder with a compact square body that can be fixed from six directions - front, back, left, right, top and bottom - and placed side by side with other units to save space on dense fixtures. As a double-rod, double-acting unit with a 32 mm bore and 40 mm stroke, it applies a theoretical push force of 402.1 N per side at 0.5 MPa (345.6 N pull), while the bumper at each end cushions the piston and magnetic-switch slots around the body accept position switches. It runs on 40 um filtered air at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
This is a genuine AirTAC part in the MD standard family, where the rod rotates freely; for rotation-free duty, select the MK no-rotating family. The trailing S confirms the magnet is fitted on this SKU, and the ports are 1/8" PT thread with a G-thread option. We confirm exact dimensions and sizing 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
Select the MDD32X40S when you need the double-rod layout's dual work faces with position feedback: the 32 mm bore gives a theoretical 402.1 N push at 0.5 MPa on each side, and the included magnet (trailing S) lets switches in the body slots confirm stroke ends in automated sequences. If rods must stay rotation-locked, choose the MKD family instead; if feedback is not needed, the non-magnetic MDD32X40 drops the S. The 40 mm stroke sits inside the bore-32 double-acting maximum of 60 mm - keep strokes conservative on compact covers. Thread is PT as listed, with G available for other piping standards. For allowable side load and exact dimensions per stroke, come to us and the datasheet.
Applications
Tote-present pick station
Twin rods lift a tote or tote stop to present goods to a picker, with the magnet and body slots confirming the raised and lowered positions for the controller, and six-direction fixing letting the cylinder bolt up under the conveyor frame.
Indexed dial-table detent
On a rotary indexing table, the double-rod body extends locking pins from both faces of a compact bracket in one motion, delivering the bore's 402.1 N push at 0.5 MPa while switch feedback verifies the detent is fully engaged each cycle.
Jig clamp with verification
Side-by-side MDD units clamp a welded assembly from two points on a checking jig, each cylinder's magnet reporting clamp-complete to the PLC so the operator cannot advance with an unclamped part, all on a narrow fixture rail.
FAQ
What does the magnet in the MDD32X40S do, and can I get thrust figures for both rod sides?
The trailing S means a magnet is built into the piston, so reed or solid-state switches seated in the slots around the body can signal end-of-stroke to your controller - the non-S MDD32X40 lacks this. On force, the 32 mm double-acting bore delivers a theoretical 402.1 N push at 0.5 MPa and 345.6 N on the pull side; with rods on both covers, each face can do useful work in the double-rod layout.
How many ways can I fix this cylinder, and are stroke and dimensions unrestricted?
The square body accepts fixing from six directions - front, back, left, right, top and bottom - and units mount side by side to save space. Stroke for the bore-32 double-acting series runs up to 60 mm, but the compact covers reward short strokes; an over-long stroke raises side load on the rods, and the allowable side-load figure is not published here. Confirm exact dimensions for the 40 mm stroke and any side-load question from the datasheet or ask us.
