About the Airtac MA Stainless Steel Mini Air Cylinder MA40X300-S-CA
A 40 mm bore MA series round-body mini cylinder with a 300 mm stroke, double acting so air drives the rod in both directions, and fixed anti-impact bumper pads at each stroke end. At the standard 0.5 MPa supply it pushes with 628.3 N (about 64 kgf), a class suited to lifting, clamping and indexing jobs where a 16 mm rod has to reach across a long working distance. Inside the range 0.15-1.0 MPa (22-145 psi) it runs at 30-800 mm/s. The barrel is stainless steel with aluminium-alloy covers rolled on in a compact riveted body, and the carbon-steel rod carries a 20 um hard-chrome plating, so damp or washdown-prone spots are handled better than with painted mini cylinders. The built-in magnet is standard, letting CMSG / DMSG / EMSG switches bolt on without a special piston. With a 2:1 margin the 0.5 MPa push figure supports lifting roughly 32 kg vertically; a CA pivot back cover is fitted for swinging mounts.

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 MA Stainless Steel Mini Air Cylinder MA40X300-S-CA Is Used
Pallet gate lifting
A 628.3 N push at 0.5 MPa gives a 2:1 margin for raising roughly 32 kg, so the MA40X300-S-CA can lift pallet stop gates or conveyor diverters along a 300 mm travel path.
Carton ejector on packaging lines
The long 300 mm reach sweeps finished cartons off a belt from a CA pivot-mounted lever, and the stainless round barrel stands up to routine washdown in food-packaging areas.
Lift-and-lower fixture feed
Vertical raise of jigs or fixture plates up to the 32 kg safe-lift class works well here; switch signals from a bolt-on CMSG or EMSG switch confirm top-of-stroke before the next cycle.
Is the Airtac MA Stainless Steel Mini Air Cylinder MA40X300-S-CA the Right Cylinder?
Compare both directions of the MA range before locking in: the MA32 gives 402.2 N push at 0.5 MPa if your load is lighter and you want a slimmer body, while loads beyond about 628 N should move up to the MAC family, which adds 50 mm and 63 mm bores plus adjustable air cushioning. Keep in mind this cylinder does not hold position if air is lost or the valve is centred - the piston drifts - so add a rod lock or pilot check valve where the load must stay put. The CA pivot back cover on this model suits linkages and swinging levers; FA flange, LB foot or SDB pivot brackets can be ordered alongside. A 300 mm stroke exposes 16 mm of hard-chrome rod over a long reach, so guide the load to keep side loads off the rod bearings. Position feedback via CMSG / DMSG / EMSG switches needs no magnet option - it is supplied with one.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MA Stainless Steel Mini Air Cylinder MA40X300-S-CA FAQ
At 0.5 MPa the 40 mm bore pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa these rise to 879.6 N push and 738.9 N pull. The theoretical maximum at 1.0 MPa is 128.1 kgf. It is double acting, so air controls both the extend and return strokes, with 1/8" ports and an M12x1.25 male rod thread on the 16 mm rod.
They are fixed anti-impact pads that soften the blow at each stroke end by decelerating the moving parts - they cannot be adjusted and they do not lock or hold the piston. If air pressure drops, the rod will drift under load. For load holding, add a rod lock or a pilot check valve; for adjustable air cushioning, look at the MAC series instead.
