About the Airtac MA Stainless Steel Mini Air Cylinder MA40X200-S-CA
The MA40X200-S-CA is the largest bore in AirTAC's round-body MA series paired with a 200 mm stroke and the CA pivot back cover. Air drives the rod in both directions, and fixed anti-impact bumper pads take the sting out of stroke end. With a 16 mm hard-chrome plated rod and 1/8 inch ports, it delivers 628.3 N push and 527.8 N pull at 0.5 MPa, rising to 879.6 N push at 0.7 MPa. Practically, that means you can plan on roughly 377 N of real working thrust at 0.5 MPa once you derate the rating, or about 32 kg of vertical lift with a 2:1 margin. The riveted stainless barrel shrugs off washdown and humid plant air far better than painted-steel minis, and the magnet built into every MA piston means a CMSG, DMSG or EMSG switch clamps straight on with no special order.

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 MA40X200-S-CA Is Used
Case ejector on carton lines
Around 377 N of derated thrust at 0.5 MPa pushes filled cartons off a conveyor lane briskly at the 30-800 mm/s speed range, while the stainless barrel copes with frequent wipe-downs.
Lifting a 30 kg fixture gate
Halving the 64 kgf vertical-lift equivalent leaves a 2:1 margin, so a jig gate or clamp beam near 30 kg lifts reliably; the CA pivot eye suits a linkage that swings as it rises.
Bottle-capper press head
Up to 879.6 N at 0.7 MPa seats caps or presses bearings in bottling and assembly cells, with fixed bumper pads softening each downstroke without an adjustment chore.
Is the Airtac MA Stainless Steel Mini Air Cylinder MA40X200-S-CA the Right Cylinder?
Sizing check: a 32 mm MA gives 402.2 N push at 0.5 MPa, so if your load sits under about 240 N the MA32X200 costs less; above that, this 40 mm unit is the right step. Need more than 880 N or an adjustable air cushion? Move up to the MAC family, which adds 50 and 63 mm bores with variable cushioning. Note that a plain MA drifts when air is removed, so hang a pilot check valve or rod lock on any load that must stay put. The CA back cover gives you a pivot eye at the rear, and FA flange, LB foot or SDB pivot brackets bolt on if the frame needs a fixed mount. At 200 mm of stroke, keep the rod load pure axial - side loads bend the 16 mm rod and chew the bushing, so guide the part externally. Operating window is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
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 MA40X200-S-CA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those figures climb to 879.6 N and 738.9 N. Theoretical maximum is 128.1 kgf at 1.0 MPa. Air pressure runs 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speed spans 30-800 mm/s. Ports are 1/8 inch, the rod is 16 mm with an M12x1.25 male thread, and the 200 mm stroke is a standard length for this bore.
The barrel is high-precision stainless steel rolled onto aluminium-alloy covers, so the cylinder tolerates damp, washdown-prone or outdoor spots where painted minis rust. The CA back cover provides a rear pivot eye, letting the cylinder swing with a lever or linkage without extra brackets. A magnet is built into the piston as standard, so CMSG, DMSG or EMSG reed switches snap on for end-of-stroke signalling.
