About the Airtac MA Stainless Steel Mini Air Cylinder MA40X225-S-CA
This 40 mm bore, 225 mm stroke MA cylinder delivers 628.3 N of push and 527.8 N of pull at 0.5 MPa, rising to 879.6 N at 0.7 MPa - the strongest bore in the MA range. The CA pivot back cover gives you a clevis-style mounting eye straight from the factory, so swinging or tracking motions need no add-on bracket. It is double acting, with fixed anti-impact bumper pads that take the sting out of stroke ends without acting as an adjustable cushion. The body is a rolled, riveted stainless-steel round barrel paired with a 16 mm hard-chrome plated carbon-steel rod, a combination that shrugs off washdown mist and outdoor damp far better than painted minis. Every MA unit carries its magnet as standard, so a CMSG, DMSG or EMSG switch clips on for end-of-stroke signals with no special-order piston. In practice, plan on roughly 377 N of usable 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 MA Stainless Steel Mini Air Cylinder MA40X225-S-CA Is Used
Bottling line gate diverter
Swings a guide gate across a bottle conveyor at a filler infeed; the CA pivot eye matches the gate's swinging arc and 628 N at 0.5 MPa far exceeds the light divert force needed.
Fixture nest lift in a machining cell
Raises a roughly 30 kg aluminium fixture nest between drilling stations, using the 64 kgf theoretical vertical-lift figure at 0.5 MPa halved for a safe 2:1 margin.
Weld jig clamp actuator
Presses a swing clamp arm on a weldment jig, where the stainless barrel and chrome rod cope with weld-spatter mist and the bumper pad softens clamp touchdown.
Is the Airtac MA Stainless Steel Mini Air Cylinder MA40X225-S-CA the Right Cylinder?
Weigh the job against neighbours in the range: the 32 mm bore makes about 402.2 N at 0.5 MPa if you are over-sized, while stepping to the MAC 50 mm family (which adds variable air cushioning and larger bores) makes sense when deceleration must be tuned. Keep in mind the MA drifts freely the moment air is removed or the valve centres - it holds nothing on its own - so add a rod lock or pilot check valve wherever a load must stay put. With 225 mm of travel on a 16 mm rod, guide the load externally or keep side forces low to avoid rod bending, and prefer the SDB pivot bracket or FA flange if your frame cannot accept the CA eye. Because 225 mm sits well inside the 500 mm standard limit for this bore, it is a catalogue item; PT ports come as built, with G and NPT threads available to order. The fitted magnet means CMSG / DMSG / EMSG switches work out of the box.
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 MA40X225-S-CA FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa those figures climb to 879.6 N push and 738.9 N pull. The theoretical maximum for the 40 mm bore is 128.1 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-800 mm/s. The 225 mm stroke is a standard length for this bore, which accepts up to 500 mm.
The CA pivot cover replaces the plain rear end with a pivoting eye, letting the cylinder swing with a lever, gate or linkage instead of being bolted rigid. If the machine needs a fixed base instead, the LB foot, FA flange or SDB pivot bracket bolt on, and I or Y rod knuckles can be fitted at the front. The 1/8" air ports take PT fittings as supplied, with G and NPT thread variants offered to order.
