Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SU 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 MAC40X180SU
A 180 mm stroke backed by 628 N of push at 0.5 MPa (72.5 psi) makes the MAC40X180SU a fit for slide and gate jobs where shorter minis stall. Air drives the rod both ways - double acting - and needle screws at each end give a variable air cushion you open gradually until end-of-stroke knock disappears; at 0.7 MPa the same bore pushes 880 N.
Around the piston, the barrel is stainless steel rolled onto aluminium covers, a riveted round-body build that copes with condensation, splash and outdoor rain far better than painted minis. Treat 628 N as the ceiling and expect about 377 N of usable push at 0.5 MPa once seals and line losses take their share. A magnet comes standard, so CMSG, DMSG or EMSG switches drop straight on.

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 MAC40X180SU Is Used
Carton gate
Kicks cartons between lanes on a case-packing line; 528 N of pull resets the gate at full conveyor speed.
Glue-head press
Presses a hot-glue shoe onto tray flaps through a 180 mm stroke in the damp air of a food plant.
Bin lifter
Raises a 25 kg bin off a tote conveyor - about 32 kg of vertical lift with a 2:1 margin on the 64 kgf rating.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X180SU the Right Cylinder?
If 402 N from a 32 mm bore is short and 981 N from a 50 mm is more than the job needs, this 40 mm barrel sits in the middle at 628 N push and 528 N pull at 0.5 MPa. Nothing in the cylinder holds position once air is removed - the piston will sag or drift - so add a pilot check valve or step up to a rod-lock version where parking matters. The U flat-end back cover bolts flush to brackets without clevis hardware; FA flange, LB foot and SDB pivot options cover fixed or pivoted bases. Keep the 16 mm rod free of side load across the 180 mm travel, or fit external guide rails.
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 MAC40X180SU FAQ
Bore 40 mm, rod 16 mm, 1/8 in air port, rod thread M12x1.25. Push is 628 N and pull 528 N at 0.5 MPa; at 0.7 MPa push is 880 N and pull 739 N; theoretical maximum force is 128.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The rolled stainless barrel and hard-chrome 16 mm rod shrug off condensation and washdown splash that pit painted mini cylinders. Cushion needles at both ends are backed fully off for start-up, then closed gradually to tune the stop.
