Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 220mm 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 MAC25X220SCA
For a 220 mm reach from a compact body, this 25 mm-bore MAC double-acting cylinder pushes 245.3 N and pulls 206.1 N at 0.5 MPa, with air fed to both sides so the rod extends and retracts under power. A variable air cushion at each end soaks up end-of-stroke shock as cycle speeds climb toward 800 mm/s.
Derate before you size: plan on roughly 147 N of continuous working force at 0.5 MPa, about 60 percent of the rating, which is enough to lift around 12 kg vertically with a 2:1 margin. The riveted stainless barrel and hard-chromed 10 mm rod shrug off washdown and damp air, and because the magnet is built in as standard, CMSG, DMSG or EMSG switches bolt straight on - no special-order piston needed.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MAC25X220SCA Is Used
Packaging line pusher
Sweeps cartons 220 mm sideways on a snack-food infeed conveyor at up to 800 mm/s, with the cushion damping the hit at the stop.
Lab carousel indexing
Rotates a small sample carousel on a clevis linkage, the CA pivot cover taking the pin without adapter brackets.
Proofing-chamber door lift
Raises a 12 kg bakery proofing-chamber door through 220 mm, right at the cylinder's 2:1 vertical-lift margin.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCA the Right Cylinder?
At 245.3 N push, bore 25 sits between the 20 mm frame (157.0 N at 0.5 MPa) and the 32 mm frame (402.2 N at 0.5 MPa) - step down for light slides, up once friction pushes your duty past about 147 N. Note the MAC has no positional lock: centring the valve lets the piston drift, so add a rod lock or pilot check valve if the load must stay put. The CA pivot back cover takes a clevis-style linkage directly, while FA flange, LB foot or SDB pivot brackets cover fixed frames, and the standard magnet drives CMSG/DMSG/EMSG switches. With 220 mm of stroke on a 10 mm rod, keep side loads off the rod and guide the payload externally.
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 MAC25X220SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures are 343.4 N push and 288.5 N pull. The theoretical maximum at 1.0 MPa is 50.0 kgf. Run it on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um, with proof pressure of 1.5 MPa (215 psi). The air connection is a 1/8 inch port.
The CA cover provides a pivot eye, so a clevis linkage can follow the long 220 mm travel without binding the rod. Needle-screw cushions at both ends should be backed off on first run and closed gradually until end-of-stroke impact disappears at your working speed.
