Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 180mm 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 MAC40X180SCA
Two air ports drive the MAC40X180SCA in and out - it is double acting end to end, with a variable air cushion at each end tuned by needle screw. At the common 0.5 MPa (72.5 psi) supply the 40 mm bore pushes 628 N (about 64 kgf) and pulls 528 N, enough for trays, gates and small press heads; step up to 0.7 MPa and push reaches 880 N.
The riveted round barrel is stainless steel with a hard-chrome plated 16 mm rod, so it shrugs off washdown mist and outdoor damp that corrode painted mini cylinders. Plan on roughly 377 N of real working force at 0.5 MPa rather than the full 628 N rating, leaving margin for friction and line loss. The magnet is built in as standard, so a CMSG, DMSG or EMSG switch clips on for end-of-stroke signal.

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 MAC40X180SCA Is Used
Bottle-line pusher
Diverts filled 6-packs off a bottling conveyor; 628 N at 0.5 MPa moves a full stack with margin to spare.
Small press head
Drives a marking or snap-fit head through a 180 mm approach on electronics and appliance assembly stands.
Gated indexing
Swings a gate arm on the CA clevis pin between stations while a DMSG switch confirms each index position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SCA the Right Cylinder?
Compare across bores by 0.5 MPa push: a 32 mm barrel gives about 402 N, this 40 mm gives 628 N, and the 50 mm reaches 981 N - pick the 40 when 30 to 45 kg of push is the job. If your valve centres or the air drops, the rod drifts freely; fit a pilot check valve or a rod-lock cylinder when a load must stay parked. The CA pivot back cover takes a clevis or trunnion pin directly, and FA flange, LB foot or SDB pivot brackets bolt on for fixed bases. Over a 180 mm stroke, keep side load off the 16 mm rod or add external guides, and back the cushion screws fully off before first run.
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 MAC40X180SCA FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa push rises to 880 N and pull to 739 N; the theoretical ceiling is 128.1 kgf at 1.0 MPa. The bore is 40 mm, rod 16 mm, air port 1/8 in, rod thread M12x1.25, running 30-800 mm/s.
The magnet is included as standard, so CMSG, DMSG or EMSG switches mount with no special-order piston. Before first run, back the cushion needle screws fully off, then close them gradually to soften end-of-stroke impact.
