The AirTAC Airtac MA Mini Cylinders MA25X50SU is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 50mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Where a 50 mm envelope matters, this 25 mm bore MA cylinder keeps the full stainless round-body build. Double acting with fixed bumper pads, it pushes 245.3 N and pulls 206.1 N at 0.5 MPa (22-145 psi), climbing to 343.4 N at 0.7 MPa, and cycles anywhere from 30 to 800 mm/s.
The riveted stainless barrel with its hard-chrome plated 10 mm rod rides out condensation, mild washdown and outdoor duty, and the short stroke keeps the whole unit slim in tight fixtures. The magnet is standard, dropping a CMSG, DMSG or EMSG sensor on without special ordering. Size the real job at about 147 N of working force at 0.5 MPa, or plan on roughly 12 kg of vertical lifting once a 2:1 margin is applied.

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.
| Pressure | Push force | Pull force |
|---|---|---|
| 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.

| ×50 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
A light bench crimp for wire terminals, sized comfortably by the 245.3 N push at 0.5 MPa.
Clamps small aluminium housings on a milling fixture, with the 50 mm stroke clearing the loader arm.
Presses flap adhesive tabs on a small carton sealer, where the washdown-friendly stainless barrel pays off.
Between the 157 N MA20 below and the 402.2 N MA32 above, this 25 mm bore is the mid-size workhorse, and the 50 mm stroke suits clamping rather than long traverses. Because a plain MA drifts when the directional valve centres or pressure drops, pair it with a pilot check valve or rod lock wherever a clamped part must not move. The U flat-end back cover bolts flat to a plate, and the standard magnet keeps switch positions flexible if you later add DMSG sensing; FA flange, LB foot and SDB pivot options plus I and Y rod knuckles cover the rest.
Quick checklist
Rated 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, topping out at 50 kgf theoretical at 1.0 MPa. Bore is 25 mm, the 10 mm rod has an M10x1.25 male thread, the port is 1/8", and the 50 mm stroke sits within the 500 mm standard range.
No. Every MA ships with a built-in magnet, so a CMSG, DMSG or EMSG switch snaps onto the stainless barrel at any mid-stroke point without ordering a sensable variant - the piston is already prepared for it.
