Airtac MDD Multi-position Double Rod Cylinder MDD32X40
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD32X40 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 MDD32X40
The MDD32X40 is an AirTAC multi-mount cylinder whose compact square body fixes from six directions - front, back, left, right, top and bottom - and lets identical units be mounted side by side to save space. This double-rod, double-acting unit has a 32 mm bore and 40 mm stroke, giving a theoretical push force of 402.1 N per side at 0.5 MPa (345.6 N on the pull side), with magnetic-switch slots around the body and a bumper cushioning the piston at each end. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and speeds of 30-500 mm/s.
This is a genuine AirTAC part from the MD standard family, where the rod is free to rotate; where rotation must be prevented, the MK no-rotating family is the counterpart. This SKU carries no magnet - the trailing S is absent - so order the magnet-equipped version if you need position sensing. Ports are 1/8" PT thread (G thread available). 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
Pick the MDD32X40 when a job needs force from both ends of the cylinder: the 32 mm bore produces a theoretical 402.1 N push at 0.5 MPa on each face, and the double-rod layout drives two work points in sync from one body - useful for mirrored clamps or push-pull stations. If the rods must not turn under load, move to the MKD no-rotating equivalent; if one rod suffices, the plain MD series is lighter on the fixture. The 40 mm stroke is well within the 60 mm maximum for a bore-32 double-acting cylinder, though the compact covers still favour the shorter end of the range. Note this SKU has no magnet (no trailing S); add the S version if switches are planned. PT thread is standard here, with G available. Route allowable side-load questions to us and the datasheet.
Applications
Mirrored press-fit station
The two rods of the double-rod body press from opposite faces at once, so a single MDD32X40 can seat a bushing into a housing from one side while an anvil reacts on the other, delivering the bore's 402.1 N push at 0.5 MPa to each work point.
Pallet-gate sequencing
Fixed through the top or bottom face beside a conveyor, the cylinder lifts and lowers a gate arm with its 40 mm stroke, the bumper softening each stop, while side-by-side mounting keeps several gates on one compact rail.
Fixture positioning pins
In a machining fixture, twin rods advance locating pins into two bushings simultaneously from a single cylinder body, with the six-direction fix letting the unit bolt flat against the base plate where space is tight.
FAQ
Why choose the MDD32X40 double-rod model over a standard MD of the same bore?
The MDD double-rod layout extends rods from both covers, so one cylinder serves two work points - pushing or carrying from either face in sync - at a theoretical 402.1 N push per side at 0.5 MPa for the 32 mm bore. A standard MD has a single rod, which is simpler if you only work on one side. Both allow rod rotation; if rotation must be prevented, use the MKD no-rotating family instead.
Does this model sense position, and what stroke should I stay within?
No - MDD32X40 has no trailing S, so it is supplied WITHOUT a magnet; choose the MDD32X40S if you want switch slots to report piston position. On stroke, the bore-32 double-acting table goes up to 60 mm, but the compact covers favour short strokes: an over-long stroke increases side loading on the rod, and the allowable side load is not a figure we publish here, so confirm it from the datasheet or ask us.
