Airtac MAC Stainless Steel Mini Air Cylinder MAC40X125SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X125SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 125mm 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 MAC40X125SCAH
AirTAC builds the MAC40X125SCAH around the same riveted round barrel as the rest of the MA family: double acting with a variable cushion at both ends, a stainless tube, and a 16 mm carbon-steel rod hard-chrome plated to 20 um. With a 40 mm bore and 125 mm stroke it pushes 628.3 N and pulls 527.8 N at 0.5 MPa - enough to lift roughly 64 kg against gravity, or about 32 kg with a comfortable 2:1 margin. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.
Behind the rod, the CA pivot cover accepts a swing link straight off the machine frame, while the built-in magnet ships as standard, so a CMSG, DMSG or EMSG switch drops on for stroke-end signals without any special-order piston. The H at the end of the code marks an extra option - confirm the exact variant from the datasheet before ordering. The two-way piston seal also traps grease in its pockets, so the cylinder keeps sealing through long cycles with minimal attention.

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 MAC40X125SCAH Is Used
Weld fixture clamp
Swings a clamp arm onto a sheet-metal jig; 628 N at 0.5 MPa holds the seam while the robot welds, and the cushion quiets each cycle.
Pallet stop lever
Rises into the path of pallets on a roller lane; about 377 N of working force stops a coasting 200 kg pallet without shock loading.
Carousel index pin
Locks a rotating parts carousel between indexes; the pivot cover follows the linkage and the magnet fires a DMSG switch at full lock.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X125SCAH the Right Cylinder?
Drop to a 32 mm bore (402.2 N push at 0.5 MPa) for lighter clamps, or step up to 50 mm (981.3 N) when the load creeps past 380 N in service. Because the MAC is plain double acting, a centred valve or lost air lets the piston drift - it will not hold a raised load, so spec a rod lock or pilot check valve for that job. The SDB pivot bracket or LB foot can be added if the CA eye does not match your frame, and over 125 mm of travel the hard-chrome rod should be shielded from chips and side thrust.
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 MAC40X125SCAH FAQ
Push at 0.5 MPa is 628.3 N and pull is 527.8 N; at 0.7 MPa you get 879.6 N pushing and 738.9 N pulling, with a theoretical maximum of 128.1 kgf at 1.0 MPa. Air ports are 1/8" and the 16 mm rod carries an M12x1.25 male thread.
The barrel is stainless steel and the rod is hard-chrome plated carbon steel, so splash, condensate and washdown mist that pit painted-aluminium minis leave this cylinder's sealing surfaces intact. That is why food lines, outdoor gates and coolant-heavy cells specify the riveted round MA body over painted alternatives.
