Airtac MAC Stainless Steel Mini Air Cylinder MAC40X260SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X260SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 260mm 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 MAC40X260SCA
With a 40 mm bore and a 260 mm stroke, the MAC40X260SCA is a double acting mini cylinder with a variable air cushion at both ends. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N, climbing to 879.6 N at 0.7 MPa; working pressure spans 0.15-1.0 MPa (22-145 psi) and rod speed 30-800 mm/s. Back the cushion needle screws off on first run, then close them gradually to trim end-of-stroke shock on fast, heavy moves.
The riveted stainless round barrel and 20 um hard-chrome plated rod stand up to washdown and humid air far better than painted minis, a real edge in food and outdoor cells. Plan on roughly 377 N of usable force at 0.5 MPa - about a 32 kg vertical lift with a 2:1 margin. The CA pivot back cover swings on a clevis pin directly, and the built-in magnet ships as standard, so CMSG, DMSG or EMSG switches drop on without a 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 MAC40X260SCA Is Used
Pallet gate lifting
Swinging a 30 kg conveyor gate through 260 mm on a packaging line, with the air cushion tuned so the gate never slams its stop.
Carton push-off
Pushing cartons sideways off a transfer conveyor, where 628 N of push at 0.5 MPa clears stuck or overloaded packs.
Fixture arm indexing
Indexing a pivoting fixture arm in a machining cell; the CA pivot cover mounts straight to the pin with no adaptor bracket.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X260SCA the Right Cylinder?
Downsize to the 32 mm bore (402.2 N push at 0.5 MPa) for lighter clamping, or step up to the 50 mm bore (981.3 N) when the load grows. Note that the piston drifts freely once air is removed or the valve centres - for a load that must stay put, add a rod lock or pilot check valve rather than relying on the cushion. The CA pivot back cover pairs with SDB pivot brackets, while FA flange and LB foot options cover fixed mounts. At 260 mm of stroke, guide side loads outside the cylinder so the 16 mm rod sees pure push and pull only.
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 MAC40X260SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa, 879.6 N push and 738.9 N pull. Theoretical maximum is 128.1 kgf at 1.0 MPa. Bore is 40 mm with a 16 mm rod, 1/8" ports, M12x1.25 male rod thread, 260 mm stroke, double acting with a variable cushion at both ends, and a built-in magnet as standard.
Back both cushion needle screws fully off before start-up, run the cylinder, then close them gradually until end-of-stroke shock disappears. The standard magnet needs no special piston - CMSG, DMSG and EMSG switches clip to the stainless barrel for reliable end-of-stroke signalling.
