Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 190mm 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 MAC40X190SCM
Where a pivoting tool needs reach, the MAC40X190SCM pairs a 190 mm stroke with 628 N of push at 0.5 MPa (72.5 psi) and 528 N of return pull, rising to 880 N at 0.7 MPa. Air drives the piston both ways, and needle-screw air cushions at each end absorb the shock of full-speed stops so covers and tooling last longer.
The round barrel is stainless steel, rolled onto aluminium covers over a hard-chrome plated rod - riveted construction that stands up to washdown, rain and coastal air. Expect around 377 N of dependable working push at 0.5 MPa after friction, rather than the 628 N headline. A magnet ships in the piston as standard, so a CMSG, DMSG or EMSG switch signals stroke ends from day one.

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 MAC40X190SCM Is Used
Swing clamp
Clamps a machining-fixture door through a 190 mm swing on the CM pivot pin; 528 N of pull releases it quickly.
Sluice gate
Drives a small water-treatment sluice or damper where wet air and outdoor rain demand the stainless barrel.
Case ejector
Ejects filled cases off a palletiser infeed; about 377 N of usable push copes with a 25 kg case plus friction.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCM the Right Cylinder?
With 402 N from a 32 mm bore and 981 N from a 50 mm at the same 0.5 MPa, this 40 mm barrel is the middle choice at 628 N. A cushion softens the last few millimetres of travel but is not a brake - cut the air and the rod drifts, so use a pilot check valve or rod lock for loads that must stay put. The CM round-end back cover carries a pivot pin in a clean rounded profile; FA flange, LB foot and SDB pivot brackets cover base mounting. Guide the load externally on 190 mm strokes to keep bending off the 16 mm rod.
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 MAC40X190SCM FAQ
40 mm bore with 190 mm stroke, 16 mm rod, 1/8 in air port and M12x1.25 rod thread. Push 628 N and pull 528 N at 0.5 MPa; push 880 N and pull 739 N at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. Proof pressure 1.5 MPa (215 psi).
The CM cover provides the pivot point in a rounded profile, so a clevis or trunnion pin fits without add-on brackets, while FA flange, LB foot or SDB pivot brackets handle fixed bases. Open both cushion needles fully before first run, then close them gradually.
