Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 75mm 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 MAC20X75SCM
With a 20 mm bore and 75 mm stroke, this MAC turns 0.5 MPa into 157 N of extend force and 131.9 N of retract force - respectable output from a barrel you can hold in one hand. Being double acting, air both pushes and pulls the rod, and the variable air cushion at each end throttles the last millimetres so fast 75 mm cycles finish quietly instead of banging.
The round stainless barrel and 20 um hard-chrome rod laugh at splash, condensation and occasional washdown that would flake a painted mini, while the CM round-end tail keeps the profile slim in tight cavities. As a sizing shortcut, the rod theoretically lifts about 16 kg at 0.5 MPa, or near 8 kg with a 2:1 reserve - and you can plan on roughly 94 N of real working push once derated. The magnet ships inside every MAC piston, so CMSG / DMSG / EMSG switches need no special-order cylinder.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X75SCM Is Used
Hopper slide gate actuator
Pushes a slide gate open on a small parts hopper above a packing bench; around 94 N of practical force at 0.5 MPa handles granulate and light castings.
Dowel press assist
Adds a controlled 157 N push to a bench fixture pressing dowels into plastic housings on a short 75 mm travel.
Indexing detent retractor
Pulls a detent pin clear on a rotary indexing table at each station, the cushion easing the pin home on re-entry.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCM the Right Cylinder?
Check the neighbours first: MAC16X75 offers 100.5 N of push at 0.5 MPa and MAC25X75 reaches 245.3 N, so pick this barrel when 157 N matches the task. Bear in mind the piston is free to coast when supply drops or the valve centres - a rod lock or pilot check valve is the answer where a load must stay parked. The 1/8" ports, 8 mm rod and M8x1.25 thread keep tooling simple, and FA flange, LB foot or SDB pivot brackets bolt to the CM tail if the frame needs a base. The 75 mm travel sits well inside the 500 mm standard stroke ceiling for this bore.
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 MAC20X75SCM FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa. Raise the supply to 0.7 MPa and you get 219.8 N push and 184.7 N pull, against a 32.0 kgf theoretical ceiling at 1.0 MPa. The operating window is 0.15-1.0 MPa (22-145 psi) and proof pressure 1.5 MPa (215 psi).
Only the tail shape: the CM cover ends in a rounded boss instead of the CA pivot ear or the flat U face, so the cylinder tucks neatly into tight spaces. FA flange, LB foot or SDB brackets still bolt on as usual, and the stainless barrel, chrome rod and standard piston magnet are identical to the rest of the MAC 20 mm range.
