Airtac MAC Stainless Steel Mini Air Cylinder MAC40X35SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X35SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 35mm 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 MAC40X35SCA
A 40 mm bore with 35 mm of stroke and a CA pivot back cover, this MAC cylinder runs double acting - air drives the rod out and pulls it back - with a variable air cushion at each end. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N, enough for clamp arms, chutes and small gates, and the built-in magnet means CMSG, DMSG or EMSG switches clip on with no special-order piston.
The riveted stainless barrel with a hard-chrome plated 16 mm rod shrugs off splash and washdown where painted minis rust through. The CA pivot cover gives swinging or rocking motion a mounting point without extra brackets, and you can plan on roughly 377 N of real pushing work at 0.5 MPa once a 40 percent reserve is kept.

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 MAC40X35SCA Is Used
Bottling line gate
Swings a divert gate on a bottling conveyor, switching 500 ml bottles between lanes at up to 800 mm/s with cushioned landings at both ends.
Weld fixture clamp
Rocks a clamp arm on an automotive weld fixture; the 628 N push holds brackets against the jig while the CA pivot cover takes the swinging motion directly.
Carton kicker
Kicks misoriented cartons off a packaging line with a quick 35 mm throw, fast enough for lines running several packs per second.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X35SCA the Right Cylinder?
Bore 40 sits mid-range: the 32 mm bore makes 402.2 N push at 0.5 MPa while the 50 mm bore reaches 981.3 N, so if the load needs more than about 377 N of working force, step up rather than overload. Ports are 1/8" and the rod thread is M12x1.25; strokes beyond 500 mm are made to order. The cushion is not a brake - with the valve centred or air lost the rod drifts, so fit a rod lock or pilot check valve where position must be held. Add FA flange, LB foot or SDB pivot brackets and I or Y rod knuckles to match the CA pivot cover.
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 MAC40X35SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa the figures rise to 879.6 N push and 738.9 N pull. The theoretical maximum at 1.0 MPa is 128.1 kgf. Working pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-800 mm/s.
Back the cushion needle screws fully off before the first strokes, then close them gradually until end-of-stroke shock disappears. The cushion is variable at both ends and works across the full 30-800 mm/s speed range, but it softens only the approach - it is not a position lock.
