Airtac MDD Multi-position Double Rod Cylinder MDD16X25S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD16X25S is a genuine MD multi-mount cylinder (double rod), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDD Multi-position Double Rod Cylinder MDD16X25S
The MD family multi-mount cylinder is a compact square-body actuator that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. This MDD16X25S is the double-rod version of the 16 mm bore standard series with a 25 mm stroke: a rod extends from both covers, so both faces can clamp, push or position with a theoretical thrust of 86.4 N per rod side at 0.5 MPa. Cushioning is a bumper, the medium is air filtered to 40 um, and the speed range is 30-500 mm/s.
This is a genuine AirTAC part in the MD (standard) family, where rod rotation is allowed - it is not the no-rotating MK family. The trailing S in the SKU means a magnet is fitted, so position sensing is supported via the switch slots around the body. Operating pressure is 0.15-1.0 MPa (22-145 psi) and temperature range is -20 to 70 C. Exact dimensions, sizing and compatible sensor details are confirmed 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
Choose the 16 mm bore when your job needs up to about 86.4 N of theoretical thrust per rod side at 0.5 MPa; larger bores in the same multi-mount body are available for higher force. MD keeps rod rotation possible, while MK prevents it. Acting choices span double acting (MD), double rod (MDD), single push (MSD), single pull (MTD), and adjustable stroke (MDJ with a 10/20/30 mm adjustable range). This 25 mm stroke sits well within the bore 16 table, which runs to 50 mm - the short covers of a multi-mount body caution against over-long strokes, so route long-stroke or side-load questions to us. The trailing S means this SKU includes the magnet; the PT thread is standard for this series with G available. Port size is M5x0.8.
Applications
Position-Checked Fixture Clamping
The double rod clamps a small part from both sides at a workstation, and the fitted magnet lets the switch slots signal clamp-open and clamp-closed positions to the controller.
Conveyor Gate with Position Signal
Mounted side by side along a light conveyor, the compact body raises a stopper gate, while the magnet feeds extend and retract position signals to the line PLC.
Slide-Plate Part Pushing
With a rod on each cover, one body can push parts onto a slide plate in one direction while the other rod handles reject or kick-off duty in a compact side-by-side layout.
FAQ
What does the S in MDD16X25S mean?
The trailing S means this cylinder is supplied with a magnet in the piston, so the magnetic-switch slots around the body accept position switches for end-of-stroke signaling. The same model without the S (MDD16X25) is the non-magnetic version. Bore 16 port size is M5x0.8 with PT thread, and G thread is available.
Can I use a long stroke on this compact body?
Bore 16 multi-mount cylinders run up to 50 mm stroke, and the short covers caution against pushing stroke lengths much beyond the table. This model is 25 mm. For side-load ratings and exact per-stroke dimensions, confirm from the datasheet or ask us.
