Airtac MAC Stainless Steel Mini Air Cylinder MAC40X5SU
The AirTAC MAC Stainless Steel Mini Air Cylinder MAC40X5SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 5mm 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 MAC40X5SU
Damp washdown cells and outdoor machinery are where painted mini cylinders fail first; the MAC40X5SU avoids that with a stainless round barrel, aluminium covers rolled on into a sealed riveted body, and a 16 mm rod hard-chrome plated to 20 um.
This is a double-acting cylinder with a variable air cushion at both ends, so even the short 5 mm stroke can be tuned to stop without shock. The magnet is fitted as standard, meaning CMSG, DMSG and EMSG switches simply snap onto the barrel. Ratings: 0.15-1.0 MPa (22-145 psi) supply, 1.5 MPa (215 psi) proof, 30-800 mm/s speed.

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 MAC40X5SU Is Used
Capper top press
Topping screw caps onto bottles on a filling line: the 628.3 N push at 0.5 MPa seats caps in a 5 mm press without crushing, cushioned so the platen lands soft.
Leak-test clamp
Clamping a test port on a leak-test station in a washdown-prone cell: the stainless barrel and hard-chrome rod shrug off splashes that quickly rust painted minis.
Lid hold-down
Holding lids during adhesive cure on an electronics assembly bench: about 377 N of working force at 0.5 MPa, with a DMSG switch confirming full clamp.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X5SU the Right Cylinder?
Sizing is simple: MAC32 develops 402.2 N push at 0.5 MPa and MAC50 develops 981.3 N, so this 40 mm bore sits between them for mid-weight presses and clamps. The U flat-end cover presents a clean fixed mounting face, and FA, LB or SDB brackets plus I and Y knuckles extend the options; the standard magnet pairs with CMSG, DMSG or EMSG switches for position signals. Remember the MAC holds nothing once air is lost - the rod follows whatever force acts on it - so add a check valve or rod lock for maintained positions.
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 MAC40X5SU FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those figures become 879.6 N and 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Pressure spans 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), and speed covers 30-800 mm/s.
The barrel is stainless steel and the 16 mm carbon-steel rod is hard-chrome plated to 20 um, while the aluminium covers are rolled onto the tube in a riveted, sealed body. That mix survives damp production halls, splashes and outdoor duty that rust painted mini cylinders quickly.
