About the AirTAC MDD20
The AirTAC MDD20 is a double-acting double-rod multi-mount cylinder with a 20 mm bore. With a rod on both sides it gives the same force each way: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa. Force depends on bore and pressure only, so every stroke on this page gives the same output.
The compact square body can be fixed from several faces and several cylinders can be mounted side by side. The piston rod exits at both ends of the body. The rod guide needs no added lubrication. All MDD20 versions use M5×0.8 air ports and run on filtered air at 0.15 to 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 500 mm/s. This page lists 17 stock order codes with strokes from 5 to 60 mm; the catalog maximum stroke is 60 mm.

Theoretical output force (Ø20 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 131.9 N | 131.9 N |
| 0.7 MPa | 184.7 N | 184.7 N |
Both directions use the bore area minus the rod area. Usable force is lower because of friction and back-pressure.

Where the MDD20 Is Used
Small pushers and stoppers
About 131.9 N at 0.5 MPa in a body that fixes from several faces.
Multi-cylinder banks
Several cylinders mount side by side to save space.
Sensed positioning
Magnet versions report stroke ends through cylinder sensors.
Choosing the Right MDD20 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Finally pick the version: S adds a magnet for position sensors.
AirTAC MDD20 FAQ
No. Every MDD20 gives about 131.9 N each way at 0.5 MPa, whatever the stroke.
