Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 700mm 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 MAC40X700SCAH
Long reach meets mid-force here: this 40 mm bore MAC yields 628.3 N forward and 527.8 N back at 0.5 MPa, with 879.6 N on tap at 0.7 MPa in a double-acting, twin-cushion package. Its 700 mm stroke exceeds the 500 mm standard limit, so the unit ships as a made-to-order build. The trailing H suffix is a non-catalogue option - confirm its exact meaning from the datasheet before ordering.
Hard-chrome plating on the carbon-steel rod paired with the stainless barrel resists rust in humid or rinsed-down corners of a plant. Sizing note: treat roughly 377 N as the dependable working push at 0.5 MPa, which equates to about a 64 kg vertical lift, or 32 kg with a 2:1 safety factor. Because the magnet ships standard, CMSG, DMSG and EMSG switches mount straight onto the barrel.

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 MAC40X700SCAH Is Used
Drum-filler lid clamp
Clamping lids onto 200 L drums before filling; about 377 N of working force holds the seal while the cushion stops the lid from bouncing at stroke end.
Bottle cross-transfer arm
Pushing bottle rows across a conveyor at a bottling plant, with a clip-on CMSG switch confirming each stroke end without touching the piston.
Press shop part ejector
Ejecting stamped brackets from a die on the upstroke; 879.6 N at 0.7 MPa clears the part and the chrome-plated rod shrugs off cutting-oil mist.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCAH the Right Cylinder?
Compared sideways, the 32 mm bore gives 402.2 N at 0.5 MPa and the 50 mm bore gives 981.3 N, so this 40 mm frame covers the middle ground where 879.6 N at 0.7 MPa is needed. With no air applied the piston is free to creep under load, so spec a rod lock or pilot check valve where position must be held. The CA pivot back cover suits SDB pivot mounting or I/Y knuckles, and FA flange or LB foot brackets handle fixed frames. On a 700 mm stroke, external guiding is essential to protect the 16 mm rod from bending under side load.
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 MAC40X700SCAH FAQ
Use 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa; the theoretical maximum is 128.1 kgf at 1.0 MPa. Port size is 1/8", rod thread M12x1.25, operating range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
The riveted stainless barrel with a 20 um hard-chrome rod handles humidity, splash and mild washdown without flaking paint or rust sealing the bore - a practical advantage in food, outdoor and coolant-heavy cells.
