Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 225mm 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 MAC40X225SCA
Pivoting duty is where the MAC40X225SCA earns its keep: the CA back cover pins into a clevis so the body can swing with the linkage while the 40 mm piston puts out 628.3 N forward and 527.8 N back at 0.5 MPa. Air works the rod in both directions, and needle-controlled cushions at each end decelerate the load smoothly across the whole 30-800 mm/s speed range.
Budget the job on roughly 377 N of continuous push, a sensible 60 percent reserve under the rating, and expect about 32 kg of vertical lift capability with a 2:1 margin built in. The magnet is included as standard, so CMSG, DMSG and EMSG switches mount with no special order. The rolling-packed stainless barrel and chrome-plated rod also handle washdown locations better than painted alternatives.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X225SCA Is Used
Lid lift on a mixing vat
Swings a stainless lid open on a food mixer; the CA clevis pin follows the arc while the cushion settles the lid at each stop.
Actuator on a lab test rig
Loads specimens at controlled force in a fatigue fixture, cycling at 30-800 mm/s with switch feedback from the standard magnet.
Presence arm on an AGV tugger
Extends a pivoting presence arm on an automated tugger; the magnet fires a CMSG switch the moment the arm is fully out.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCA the Right Cylinder?
Against its neighbours, the 32 mm bore manages 402.2 N at 0.5 MPa and the 50 mm bore 981.3 N, so this 40 mm fits mid-range linkages. With no air applied the rod slides freely - the cushion is not a brake - so hang a pilot check valve or rod lock on any load that must hold position. For the 225 mm stroke, keep side loads off the 16 mm rod and guide the payload externally; FA flange, LB foot or SDB pivot hardware completes the mount.
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 MAC40X225SCA FAQ
Rated output at 0.5 MPa is 628.3 N push and 527.8 N pull. Raise the supply to 0.7 MPa and you get 879.6 N push and 738.9 N pull, while the ceiling is 128.1 kgf theoretical at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 40 um filtered air.
No. The variable cushion only slows the last part of travel; it cannot hold a load. If the valve centres or pressure drops, the rod drifts. For hanging or lifting duties on the CA pivot, add a pilot check valve or a separate rod lock.
