The AirTAC Airtac MA Mini Cylinders MA25X25-S-CA is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 25mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A 25 mm bore MA with a 25 mm stroke and CA pivot back cover, this double-acting AirTAC mini cylinder develops 245.3 N in push at 0.5 MPa (250.2 N less rod-side loss on pull, rated 206.1 N) using 1/8-inch ports and a 10 mm hard-chrome plated rod. Fixed anti-impact bumper pads soften both stroke ends; the short 25 mm stroke keeps the whole envelope tight enough for inline machine frames. The riveted round body pairs a stainless-steel barrel with aluminium-alloy covers, so damp washdown corners and outdoor installations do not chew up a painted housing. Magnet comes built in at no extra option, so CMSG, DMSG or EMSG switches mount straight onto the barrel. Plan real work around 147 N rather than the full 245.3 N rating, or expect the rod to lift roughly 25 kg vertically, dropping to about 12 kg 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.

| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
The 245.3 N push at 0.5 MPa folds small carton flaps on a semi-auto packing bench, with the 25 mm stroke matching typical flap travel.
Mounted beside a filling line conveyor, this 25 mm bore unit kicks off-temperature bottles into a bin; the stainless barrel shrugs off rinse water splashes.
Clamps test boards in electronics fixtures where the CA pivot cover allows the cylinder to swing open for fast board loading, and the magnet feeds CMSG position feedback.
Compare the force band before ordering: the smaller MA20 delivers 157.0 N at 0.5 MPa, while the MA32 jumps to 402.2 N - if your fixture may grow heavier, step up now. Keep in mind that once the solenoid valve centres or air drops, the piston moves freely; a pilot check valve or rod lock is the fix for a held position. The CA pivot cover here pairs naturally with an SDB pivot bracket, and LB foot or FA flange plates remain available. A short 25 mm stroke keeps side-load risk low, so rod bending is not a concern at this size.
Quick checklist
At 0.5 MPa the 25 mm bore gives 245.3 N push and 206.1 N pull. At 0.7 MPa those figures rise to 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof limit, and the rod travels at 30-800 mm/s.
The CA pivot back cover gives a clevis-style mounting point built into the cylinder itself, so swinging or arc-motion installations need no extra bracket machining. It bolts directly against an SDB pivot bracket, or you can add an FA flange or LB foot for fixed mounting. Combined with the riveted stainless round barrel and standard magnet, one order covers structure and sensing.
