About the AirTAC MAR20
The AirTAC MAR20 is a double-acting stainless-steel mini cylinder with a 20 mm bore and an 8 mm piston rod. At 0.5 MPa it pushes 157 N and pulls 132 N; at 0.7 MPa that rises to 220 N push and 185 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All MAR20 versions share 1/8 air ports and an M8×1.25 rod thread. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 87 stock order codes with strokes from 5 to 600 mm; catalog standard strokes run up to 500 mm, and the longer codes are non-standard strokes that we confirm with the quote.
The MAR20 has a square front block for mounting: MARF codes are the front-fixed type and MARU codes the top-fixed type, so the block is bolted to the machine from the front or from above. Every MAR code includes the magnet (S) for position sensors, and there is no back-cover or bracket code.

Theoretical output force (Ø20 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
Push = pressure × bore area; pull subtracts the Ø8 mm rod area. Usable force is lower because of friction and back-pressure.
How the MAR20 Order Code Is Built

Where the MAR20 Is Used
Pick-and-place and transfer
About 157 N at 0.5 MPa suits pushers, stoppers and transfer slides.
Packaging machines
Carton pushers, gates and diverters on packaging lines.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right MAR20 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose how the front block is fixed: F from the front, U from above.
Every MAR code includes the magnet (S).
AirTAC MAR20 FAQ
No. Every MAR20 gives about 157 N push and 132 N pull at 0.5 MPa, whatever the stroke.
1/8 ports, PT thread as standard.
By its front block: MARF is fixed from the front, MARU from above. There is no bracket code.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single MAR20. Orders are processed and handed to the carrier within 3-5 business days.
