Airtac MAC Stainless Steel Mini Air Cylinder MAC20X205SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X205SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 205mm 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 MAC20X205SU
MAC20X205SU pairs a 205 mm stroke with the 20 mm MAC bore: a double-acting round-body cylinder that pushes 157 N and pulls 132 N at 0.5 MPa, rising to 220 N at 0.7 MPa. Air pressure drives the rod both ways, and a variable air cushion at each end soaks up the stop so the covers survive fast cycling between 30-800 mm/s.
The stainless barrel and hard-chrome plated 8 mm rod shake off the damp and the washdown that kill painted minis, and the 1/8" ports keep plumbing simple. Because the magnet is built in as standard, a CMSG, DMSG or EMSG switch clips on for end-of-stroke signalling. In practice you can hang real work off it: around 94 N of usable force at 0.5 MPa, enough to lift about 8 kg vertically.

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 MAC20X205SU Is Used
Tray gate lift
Raising a diversion gate on a bakery tray line - the 205 mm stroke clears the product lane and about 8 kg of vertical lift covers a light aluminium gate.
Long push-off arm
Kicking cartons off a 300 mm wide conveyor with 157 N of push at 0.5 MPa; the dual air cushion stops the arm slamming at full extension.
Test rig actuator
Advancing a probe across a lab test fixture where the stainless barrel resists spillage and the built-in magnet drives a DMSG switch every cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X205SU the Right Cylinder?
For a 205 mm throw, 157 N at 0.5 MPa sits between the 16 mm bore (100.5 N) and the 25 mm bore (245.3 N); step up if the job grows. Long strokes bend rods: guide the load externally and keep side force off the 8 mm rod. Note that a plain MAC drifts the moment air is removed - add a rod lock or pilot check valve if the load must stay put. FA flange, LB foot or SDB pivot brackets bolt straight on, and the U flat-end back cover takes a fixed pivot pin.
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 MAC20X205SU FAQ
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, with 32 kgf theoretical maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C. Ports are 1/8", rod thread M8x1.25, rod diameter 8 mm.
Back the cushion needle screws fully off before the first strokes, then close them gradually until end-of-stroke shock disappears. The cushion is variable air on both ends, not a fixed bumper, and it is not a brake - the piston will not hold a load if air is lost.
