Airtac MAC Stainless Steel Mini Air Cylinder MAC40X5SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X5SCA 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 MAC40X5SCA
Five millimetres of travel is often all a clamp, latch or kick-off really needs, and the MAC40X5SCA does it with 628.3 N of push and 527.8 N of pull behind the piston at 0.5 MPa. Work to roughly 377 N of that rating, or treat it as a 32 kg vertical lift with a 2:1 margin. A variable air cushion at each end lets you soften the last fraction of travel so pins and levers seat gently.
Its CA pivot back cover is the standout: the body swings on a pin and follows lever or linkage motion with no extra bracket. Air acts both ways - there is no spring return - so extend and retract behave identically, and the standard built-in magnet lets CMSG or DMSG switches flag end positions. Supply runs 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, proof 1.5 MPa (215 psi).

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 MAC40X5SCA Is Used
Swing clamp arm
A 5 mm stroke driving a pivot lever on an assembly jig - the CA pivot back cover pins straight into the linkage, and the cushion stops the arm snapping into the part.
Part kick-off
Ejecting a machined bushing off its locating pin: with a 2:1 margin the bore still handles about 32 kg of vertical lift at 0.5 MPa, ample for small steel parts.
Fixture latch pin
Retracting a locating pin on a drill jig: 527.8 N of pull at 0.5 MPa seats and frees the pin briskly, with the both-end cushion damping the final seating.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X5SCA the Right Cylinder?
Weigh the load first: MAC25 gives 245.3 N of push at 0.5 MPa for light levers, MAC50 gives 981.3 N for heavy clamps. The CA pivot eye suits swing arms and linkage-driven clamps, while U and CM back covers or FA, LB and SDB brackets handle fixed mounting. Position feedback comes with no special order - the magnet is standard, ready for CMSG, DMSG or EMSG switches. One caution: centre the valve with air off and the rod can be pushed along by the load, so fit a rod lock or pilot check valve if the clamp must hold under weight.
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 MAC40X5SCA FAQ
Push is 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa; pull is 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. Maximum theoretical force is 128.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure and 30-800 mm/s speed.
The CA pivot back cover carries a pin so the cylinder can articulate with a clamp lever or linkage; U flat-end and CM round-end covers, FA flanges, LB feet and SDB pivot brackets cover fixed installations. The built-in magnet is standard, so CMSG, DMSG or EMSG switches mount on the barrel without a special piston.
