Airtac MAC Stainless Steel Mini Air Cylinder MAC40X230SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X230SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 230mm 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 MAC40X230SCA
A 40 mm bore turns 0.5 MPa shop air into 628 N of push and 528 N of pull, and this 230 mm stroke version adds a variable cushion at each end to soften landings. The barrel is stainless steel rolled tight between aluminium covers - a riveted body that shrugs off condensation in damp workshops. Thread the 1/8 in ports, hang it on the CA pivot back cover, done.
Running a heavier or faster move at up to 800 mm/s? Open the cushion needle screws gradually on first start-up. On paper the rod lifts 64 kg against gravity at 0.5 MPa; halving that gives a comfortable 32 kg vertical lift margin for real parts.

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 MAC40X230SCA Is Used
Swing-arm degating press
Pivot mounting on the CA back cover lets the arm follow the part as 628 N shears sprue gates off moulded fittings across a 230 mm stroke.
Tote stopper at a sorter
A 230 mm stroke halts moving totes dead; the cushion needles bleed off the impact so the stop bracket survives millions of cycles.
Cycle counting on a stamper
The factory-fitted magnet trips a CMSG switch at each end, giving the PLC position feedback with no sensor-ready option to buy.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X230SCA the Right Cylinder?
If 628 N of push at 0.5 MPa is more than the job needs, drop to a 25 mm bore (245 N); if the load grows, step up to the 50 mm bore at 981 N. A centred valve or lost air lets this cylinder drift - it has no holding function, so add a check valve or rod lock for suspended loads. The CA pivot back cover suits swing arms and linkages; I and Y rod knuckles complete the pivot chain. Long 230 mm strokes amplify any misalignment, so keep the thrust in line with the rod axis.
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 MAC40X230SCA FAQ
Push at 0.5 MPa is 628 N, pull 528 N. At 0.7 MPa expect 880 N push and 739 N pull, with a theoretical peak near 128 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
No. The magnet comes built in as standard, so CMSG, DMSG or EMSG reed switches snap onto the barrel anywhere along the 230 mm stroke and are ready to wire immediately.
