Airtac MAC Stainless Steel Mini Air Cylinder MAC40X220SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X220SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 220mm 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 MAC40X220SU
The flat-end U back cover on the MAC40X220SU lets the cylinder bolt flush against a machine plate with no brackets in the way. Inside it is a 40 mm double-acting mini: 628.3 N of push at 0.5 MPa and 527.8 N pulling back, with an adjustable air cushion at both ends to slow the load before it reaches the covers.
Corrosion resistance is built into the construction - a stainless-steel barrel riveted to aluminium covers, with a 20 um hard-chrome coat on the carbon-steel rod - so the body survives humid food plants and outdoor gates where painted minis flake. Work on the safe side of 377 N at rated pressure, and hung vertically each unit raises roughly 32 kg with a 2:1 margin. A standard magnet accepts CMSG, DMSG or EMSG switches for stroke signalling.

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 MAC40X220SU Is Used
Vertical part lift at a pick station
Raises tote trays of about 32 kg between picking shelves; keep a 2:1 margin under the 628.3 N push and add a check valve so trays do not sink on air loss.
Slide actuator on a transfer unit
Bolted flush through the U cover, it drives a linear slide that indexes parts between two fixtures on a rotary table.
Slide bolt on a machine guard
Pushes a guard bolt home on a milling machine enclosure; the double cushion eases both the lock and the release stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X220SU the Right Cylinder?
For this 220 mm stroke, compare the 32 mm bore (402.2 N push at 0.5 MPa) if you want to trim air consumption, or the 50 mm bore (981.3 N) if the clamp needs more bite. The piston is not held when air is removed, so a pilot check valve or rod lock protects any raised load. The U cover takes through-bolts directly; add FA flange or LB foot for frame mounting, SDB for a pivoting base, and I or Y knuckles where the rod joins a lever.
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 MAC40X220SU FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa it reaches 879.6 N and 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. It runs double-acting on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
The barrel is stainless steel rolled onto aluminium covers, and the 16 mm rod carries a 20 um hard-chrome layer, so splash zones, coolant mist and outdoor humidity do not eat the cylinder the way they ruin painted minis. The cushion screws at each end are backed off on first start-up, then closed gradually to set the deceleration.
