Airtac MAC Stainless Steel Mini Air Cylinder MAC40X80SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X80SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MAC40X80SCA
Pivot-mounted linkages are where the MAC40X80SCA earns its keep - the CA back cover swings on an integral pin eye, so the rod stays aligned through its arc with no separate clevis. With 80 mm of stroke it pushes 628 N and pulls 528 N at 0.5 MPa, rising to 880 N at 0.7 MPa, all double acting with a variable cushion at each end.
Vertical duty works out to roughly 64 kg of theoretical lift at 0.5 MPa, so hoisting about 32 kg keeps a 2:1 margin for a real gate, lid or lever. AirTAC rivets the aluminium covers and stainless block onto a stainless tube, and 20 um of hard chrome on the 16 mm rod shrugs off abrasive dust and damp air alike. The magnet is already in the piston - CMSG, DMSG and EMSG switches simply clip onto the barrel.

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 MAC40X80SCA Is Used
Pivoting chute on a parcel sorter
Tilts a gravity chute between two outbound lanes; the CA pivot eye follows the chute arc, sparing the 16 mm rod from side bending.
Vessel lid clamp in a dairy CIP area
Clamps an inspection lid on a milk line vessel; the stainless round body survives daily caustic washdown better than coated mini cylinders.
Toggle linkage on a robotic weld fixture
Actuates a toggle clamp on a weld cell fixture; about 377 N of usable push at 0.5 MPa closes the clamps with margin, and an EMSG switch reports clamp state.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X80SCA the Right Cylinder?
If 628 N at 0.5 MPa is more than you need, the 32 mm bore manages 402 N; if you are near the limit, the 50 mm bore delivers 981 N. Ports are 1/8" and the male rod thread is M12x1.25. A centred valve or lost air supply leaves the piston free to drift - the cushion only softens the stop, it never locks - so fit a rod lock or pilot check valve where the load must stay put. Add an FA flange or LB foot if the job calls for a fixed mount instead, and pair the standard magnet with CMSG / DMSG / EMSG switches for stroke-end feedback.
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 MAC40X80SCA FAQ
At 0.5 MPa: 628 N extending and 528 N retracting. At 0.7 MPa: 880 N and 739 N. The theoretical ceiling is 128 kgf at 1.0 MPa. The double-acting piston runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), with speeds of 30-800 mm/s.
Its integral pivot eye lets the cylinder swing with a lever, linkage or hinged gate, removing misalignment stress from the rod. Fixed installations can use FA flange or LB foot mounts instead, or switch to U or CM back covers. The piston magnet comes as standard, so adding a CMSG, DMSG or EMSG sensor for stroke-end signalling needs no modification.
