Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MAC40X100SUH
Punching well above its 40 mm size, the MAC40X100SUH develops 628 N of push and 528 N of pull at 0.5 MPa, and 880 N against 739 N on the return at 0.7 MPa, topping out at a theoretical 128.1 kgf. It is double acting with a variable air cushion at both ends, so end-of-stroke shock can be tuned out instead of hammering the covers.
The body is a stainless round tube rolled tight onto aluminium covers - a riveted mini cylinder that tolerates washdown better than painted-steel minis. Ports are 1/8", the rod is 16 mm hard-chrome steel, and the magnet is standard, ready for CMSG, DMSG or EMSG switches. Worked into real numbers, that is about 377 N of dependable push at 0.5 MPa, or roughly 32 kg lifted vertically with margin.

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 MAC40X100SUH Is Used
Autoclave feed elevator
Lifting instrument trays of about 32 kg vertically into a steriliser feed, where the stainless body tolerates humid heat cycles that rust plain steel tubes.
Sortation-lane pallet stop
Stopping a rolling pallet takes the full 880 N push at 0.7 MPa, with EMSG switches reporting the stop position back to the sorter controller.
Filler-head lid eject
Ejecting caps above a filling head uses the 528 N return pull, kept shock-free by the cushion at the retract end of the 100 mm stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SUH the Right Cylinder?
For context, a 32 mm bore pushes 402 N at 0.5 MPa and a 50 mm bore 981 N, so this 40 mm barrel covers the middle ground with 628 N. Keep side loads off the 16 mm rod - guide the load externally if the tooling overhangs. Note that the trailing H in the model code is not a listed option in the standard MA ordering system, so confirm its exact meaning from the datasheet before ordering. Holding position with air off requires a rod lock or pilot check valve; the cushion never acts as a brake.
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 MAC40X100SUH FAQ
Push at 0.5 MPa is 628 N and pull 528 N; at 0.7 MPa it is 880 N and 739 N. The theoretical maximum reaches 128.1 kgf. Air supply spans 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
Yes - the stainless round barrel, rolled and riveted covers, and hard-chrome plated 16 mm rod resist the splash and humidity found in food and outdoor plants far better than painted-steel minis. Air should be filtered to 40 um, and the operating window is -20 to +70 C.
