About the AirTAC MK20
The AirTAC MK20 is a double-acting non-rotating multi-mount cylinder with a 20 mm bore. At 0.5 MPa it pushes 157.1 N and pulls 131.9 N; at 0.7 MPa, 219.9 N push and 184.7 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
The rod does not rotate, so tooling stays aligned. The compact square body can be fixed from several faces and several cylinders can be mounted side by side. The rod guide needs no added lubrication. All MK20 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 24 stock order codes with strokes from 5 to 80 mm; the catalog maximum stroke is 60 mm, and the longer codes are non-standard strokes we already supply.

Theoretical output force (Ø20 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 157.1 N | 131.9 N |
| 0.7 MPa | 219.9 N | 184.7 N |
Push = pressure × bore area; pull subtracts the Ø8 mm rod area. Usable force is lower because of friction and back-pressure.

Where the MK20 Is Used
Small pushers and stoppers
About 157.1 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 MK20 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 MK20 FAQ
No. Every MK20 gives about 157.1 N push and 131.9 N pull at 0.5 MPa, whatever the stroke.
M5×0.8 ports.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa), 30 to 500 mm/s and -20 to +70 °C on filtered air.
Usually yes. Request a quote with the stroke and version and we will confirm whether it can be built, plus price and lead time.
No. You can order a single MK20. Orders are processed and handed to the carrier within 3-5 business days.
