Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MAC40X200SCM
Where a 200 mm reach has to end in a bolted, fixed nose rather than a swinging joint, the MAC40X200SCM pairs the 40 mm AirTAC mini bore with a CM round-end back cover. It is double acting with a variable air cushion at both ends, driving 628 N of push and 528 N of pull at 0.5 MPa (72.5 psi), and up to 880 N of push at 0.7 MPa (101.5 psi).
The stainless round barrel and hard-chrome 16 mm rod shrug off washdown and mild corrosion, a genuine edge over painted minis in damp food plants or outdoor rigs. For vertical work, the 628 N push converts to a 64 kg lift on paper, so size the load at roughly 32 kg to keep a 2:1 margin. A magnet is already in the piston, so CMSG, DMSG and EMSG switches clip on with no special-order piston.

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 MAC40X200SCM Is Used
Washdown conveyor stopper
A stop-and-release blade on a meat-plant conveyor line, where the stainless barrel survives daily hose-down that would rust a painted mini.
Battery hoist assist
Assisting a 30 kg battery lift on a warehouse charging station: 628 N covers about 32 kg vertically at a 2:1 safety factor.
Vibration-table drive stroke
Driving a test-bench shaker plate through 200 mm while the twin cushions tame the bounce at each reversal.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SCM the Right Cylinder?
Compare before you commit: the 32 mm bore gives 402 N push at 0.5 MPa while the 50 mm bore jumps to 981 N, so 40 mm fits mid-range jobs around 300 N of real duty at 60% of rating. Air ports are 1/8 inch (PT blank, G or NPT optional). The piston is free to drift the moment air is removed, so a pilot check valve or rod lock is the answer wherever the 200 mm stroke must stop and stay. The CM cover takes straight bolted fixings; add an FA flange, LB foot or SDB bracket if the machine needs one.
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 MAC40X200SCM FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa those become 879.6 N and 738.9 N. Maximum theoretical force is 128.1 kgf at 1.0 MPa, and proof pressure is 1.5 MPa (215 psi).
No - the piston ships with its magnet installed as standard across the MAC series. Pick CMSG, DMSG or EMSG switches and they detect the end positions straight away.
