The AirTAC AirTAC MA25X250SU Mini Cylinder 25x250 PT is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 250mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
This 250 mm stroke MA25X250SU carries the U flat-end back cover, giving you a clean fixed face for clamping brackets without ordering a separate mount. At the bore 25 size the piston delivers 245.3 N pushing at 0.5 MPa (73 psi), enough to hold roughly 147 N of real work once you keep the usual margin, and it still rides inside a compact riveted stainless barrel. The two-way piston seal carries its own grease reserve, so the round-body tube keeps running smoothly through the full 30-800 mm/s speed range between 0.15-1.0 MPa (22-145 psi). Converted for vertical work, the 245.3 N rating means the rod lifts about 12 kg with a 2:1 safety factor, handy for sizing pick-and-place heads or small lift gates against actual part weights.

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.
With 245.3 N at 0.5 MPa the bore 25 rod swings lightweight cartons off a 600 mm belt lane, and the 250 mm stroke clears a full row for batch changes.
The stainless barrel and hard-chrome rod tolerate the humid wash cabinet, and the 245.3 N push slides a loaded rack of 5 kg sample trays between stations.
Converted for vertical duty the cylinder raises about 12 kg with a 2:1 margin, lifting a hinged clamp gate on a bracket fastened to the flat-end U back cover.
Compare both neighbours before committing: a 20 mm bore pushes only 157.0 N at 0.5 MPa, while stepping up to a 32 mm bore gets 402.2 N, so the 25 mm class sits right for loads around 140-150 N. Note that when air is removed or the valve centres, the rod settles wherever the load takes it - add a rod lock or pilot check valve if the fixture must stay put. The U back cover bolts directly to machine plates, and you can add an FA flange, LB foot or SDB pivot bracket if the layout needs one. On a 250 mm stroke, guide the load externally or keep side forces off the 10 mm rod, since the rod thread is M10x1.25 and bending moment grows with stroke length. The magnet is factory fitted, so CMSG, DMSG or EMSG switches read position out of the box.
Quick checklist
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures rise to 343.4 N push and 288.5 N pull. The theoretical maximum for the 25 mm bore is 50.0 kgf at 1.0 MPa. Ports are 1/8 in on this bore, the rod thread is M10x1.25, and the cylinder is double acting with a 0.15-1.0 MPa (22-145 psi) working band.
Yes. Every MA cylinder, including the MA25X250SU, is supplied with the piston magnet already installed as a standard feature rather than an option. Snap a CMSG, DMSG or EMSG reed or hall switch onto the stainless barrel and you get end-of-stroke or mid-travel signals across the 250 mm travel without any special-order piston.
