Airtac MAC Stainless Steel Mini Air Cylinder MAC40X110SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X110SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 110mm 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 MAC40X110SU
Bolt the U flat-end cover straight to a machine plate and the MAC40X110SU becomes a compact 40 mm pusher with nothing in between. It is double acting with a variable air cushion at both ends, and at 0.5 MPa the bore delivers 628.3 N of push against 527.8 N on the return - practical capacity near 377 N, or enough to hoist roughly 32 kg vertically at a 2:1 margin. A 0.7 MPa supply lifts push to 879.6 N.
Construction is a stainless round tube rolled up with aluminium-alloy end covers and a stainless-steel block, so the body survives coolant splash and outdoor rain that eats painted mini cylinders. The 16 mm piston rod is hard-chrome plated against scoring. A piston magnet comes standard, letting CMSG, DMSG or EMSG reed switches read position anywhere along the 110 mm travel without a custom build.

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 MAC40X110SU Is Used
Small press-fit station
Bench-mounted through the U cover, the cylinder seats bushings into housings with up to about 377 N of controlled push, cushioning the seat so parts are not hammered home.
Injection mold part ejection
Rigidly fixed beside the mold platen, it pushes finished clips off the core each cycle, the 527.8 N pull retracting the knock-out pin ready for the next shot.
Fixture slide-bolt drive
The rod drives a locking pin into a drilled fixture plate; the pin, not the air, holds the fixture, so a loss of supply does not release the workpiece.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X110SU the Right Cylinder?
Compare both directions before you fix on 40 mm: the 32 mm MAC tops out at 402.2 N push at 0.5 MPa, well short once friction eats in, while the 50 mm bore offers 981.3 N for heavier ejection work. If the valve parks mid-stroke and the load must stay there, remember this cylinder drifts when air drops - a rod lock or pilot check valve is the fix. The U flat-end suits direct plate bolting, an LB foot or an FA flange, and the SDB pivot bracket converts it when the axis needs to swing.
Plumbing is a single 1/8" port per end with PT threads; the rod end thread is M12x1.25. Strokes beyond the 500 mm standard range for this bore are made to order, but 110 mm sits comfortably inside it.
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 MAC40X110SU FAQ
Force output spans a useful band: 628.3 N push and 527.8 N pull at 0.5 MPa, climbing to 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum near 128.1 kgf at 1.0 MPa. Plan jobs around roughly 377 N of working push at 0.5 MPa.
Every cylinder leaves the factory with a piston magnet, so AirTAC CMSG, DMSG and EMSG switch types clamp onto the stainless barrel and read extend and retract positions along the full 110 mm stroke - no special-order piston required.
