Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 700mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM
A 700 mm stroke on a 20 mm bore is a made-to-order build, and MAC20X700SCM delivers it in AirTAC's MA family: a stainless-steel barrel with aluminium-alloy covers rolled onto the tube for a sealed, riveted body. The cylinder is double acting - air extends and retracts the rod - with a variable air cushion at both ends, pushing 157 N at 0.5 MPa over a 0.15-1.0 MPa (22-145 psi) supply.
Run speed spans 30-800 mm/s. For sizing, plan on about 94 N of real working push at 0.5 MPa, which lifts roughly 8 kg vertically once a 2:1 margin is applied. The hard-chrome plated rod and stainless tube tolerate washdown splash that would rust painted minis, and because a magnet is standard, CMSG, DMSG or EMSG switches clip straight on without a special-order piston. The CM round-end back cover accepts pivot or fixed hardware directly.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM Is Used
Long-travel guard door
Opens a sliding acrylic guard on a packaging machine across the full 700 mm; 157 N at 0.5 MPa easily overcomes latch friction and the cushion softens the slam.
Light parts elevator
Hoists about 8 kg of aluminium fixtures between two conveyor levels, with the standard magnet feeding CMSG switches for top and bottom position signals.
Tray pusher on a bakery line
Pushes dough trays along a guide rail over a long span; the stainless barrel copes with daily hose-down washdown where painted tubes would blister.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM the Right Cylinder?
For lighter duties the bore 16 MAC manages 100.5 N at 0.5 MPa; when the load grows, bore 25 offers 245.3 N. Note that this cylinder does not lock position: with no air pressure the piston drifts freely, so a hanging load needs a rod lock or pilot check valve. At 700 mm of travel, keep thrust in line with the rod - side loading bends the 8 mm rod and wears the seals early. FA flange, LB foot or SDB pivot brackets can be added, and I or Y rod knuckles complete the setup.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC20X700SCM FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa the figures rise to 219.8 N push and 184.7 N pull. The theoretical maximum is 32.0 kgf at 1.0 MPa. The 700 mm stroke is non-standard and built to order.
Yes. The barrel is stainless steel instead of painted tube and the rod is hard-chrome plated carbon steel, so humidity and splash cause far less corrosion than on painted mini cylinders. On first run, back the cushion needle screws fully off and open them gradually to suit the load.
