Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 210mm 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 MAC20X210SCA
A 20 mm bore pushing a 210 mm stroke, the MAC20X210SCA is double acting with a variable air cushion at both ends, so end-of-stroke shock stays under control even at the top of the 30-800 mm/s speed range. At 0.5 MPa it delivers 157 N on extension and 131.9 N on retraction; at 0.7 MPa that climbs to 219.8 N. The CA pivot back cover swings on a pin, so linkage and lever jobs need no extra bracket.
The round stainless barrel and hard-chrome plated rod (20 um) shrug off mild corrosion, a real edge over painted-steel minis in damp or washdown corners. Plan on about 94 N of dependable working force at 0.5 MPa once you keep a margin, and treat this bore as lifting about 16 kg in theory - derate it to an 8 kg vertical payload for a 2:1 margin. The magnet comes built in, so CMSG, DMSG or EMSG switches drop straight on.

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 MAC20X210SCA Is Used
Swing-arm clamp on a machining fixture
The CA pivot cover pins straight into a swing clamp arm; 157 N at 0.5 MPa clamps aluminium brackets through the full 210 mm approach.
Push-off from a packaging conveyor
The rounded stainless barrel copes with washdown between shifts while the 210 mm stroke clears cartons off the belt edge.
Gate actuation on a small assembly line
Variable cushions let the gate run near 800 mm/s and still land softly, and the built-in magnet drives CMSG switches for open/closed confirmation.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SCA the Right Cylinder?
Size against neighbours: bore 16 gives 100.5 N push at 0.5 MPa and bore 25 gives 245.3 N, so pick 20 mm when 100 N is thin and 245 N is overkill. A 210 mm stroke on an 8 mm rod wants external guiding if the load can tilt; side loads bend the rod and eat the seals. The CA pivot back cover suits pin-mounted linkages, with FA flange, LB foot or SDB pivot brackets for fixed frames. Note that the piston drifts to wherever the trapped air leaves it, so a rod lock or pilot check valve is the answer for held loads.
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 MAC20X210SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N push and 184.7 N pull. Theoretical maximum at 1.0 MPa is 32 kgf. The pressure window is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The magnet is fitted as standard, so CMSG, DMSG or EMSG switches clamp onto the barrel for position signals. Air connects through 1/8" ports, with an M8x1.25 male rod thread for tooling.
