Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 30mm 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 MAC40X30SCA
A 40 mm bore double-acting mini cylinder with a short 30 mm stroke and a CA pivot back cover, the MAC40X30SCA swings on a pin without any added bracket. It carries 628 N of push at 0.5 MPa, and the variable air cushion at each end soaks up the last of the travel so faster cycles do not hammer the covers.
The riveted stainless barrel and the hard-chrome plated 16 mm rod shrug off damp, rinse-down and outdoor air far better than painted minis. For planning, count on roughly 377 N of real working push at 0.5 MPa - enough to lift about 32 kg vertically with a 2:1 margin.

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 MAC40X30SCA Is Used
Reject gate on a snack-food line
Pivots a kick-off arm that tips misshapen packs into the reject bin; 628 N at 0.5 MPa clears the 30 mm throw fast and the stainless body takes the washdown.
Ink date-code press on carton flaps
A 30 mm stroke stamps date codes on folded board, with the cushioned ends keeping the stamp crisp at 800 mm/s.
Capper swing arm on a bottling line
The CA pivot back cover swings the capper head down onto bottle necks; roughly 377 N of working push seats caps without bottoming out hard.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCA the Right Cylinder?
At 628 N per 0.5 MPa of push, this bore sits well above the 32 mm MAC32 at 402 N; step down there if the load is light, or up to the 50 mm MAC50 at 981 N for heavier parts. With the valve centred or air lost the rod drifts freely, so add a pilot check valve or rod lock wherever a stopped position must stick. The magnet is built in, so CMSG or DMSG switches clip straight on; add LB foot or FA flange mounts if the CA pivot alone does not suit the frame.
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 MAC40X30SCA FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa push rises to 880 N. Theoretical maximum is 128 kgf at 1.0 MPa. Ports are 1/8", the 16 mm rod carries an M12x1.25 male thread, pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The pivot back cover lets the cylinder rock on a pin, suiting swing arms and gate linkages with no extra bracket. Before first run, back the cushion needle screws off at both ends and open them gradually. The built-in magnet works with CMSG, DMSG and EMSG switches as standard.
