The AirTAC Airtac MA Mini Cylinders MA25X220SU is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 220mm 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 barrel with a long 220 mm reach, the MA25X220SU covers ejectors, gate pushes and slide movements that short minis cannot. It runs double acting with fixed bumper pads at each end that take the sting out of stroke-end contact - they are not an adjustable cushion, which is the MAC family's trick.
Expect 245.3 N of push at 0.5 MPa; derate to roughly 147 N of usable work so the cylinder never runs flat out, and you get about 12 kg of vertical lift with a 2:1 margin against the 25 kgf raw figure. The stainless round body and hard-chrome 10 mm rod stand up to damp air and washdown, the U flat-end cover gives a clean fixed mount, and the standard magnet accepts CMSG, DMSG or EMSG switches. Air port is 1/8 inch.

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.

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.
245.3 N at 0.5 MPa swings a lane-diverter gate on a packaging conveyor, with 220 mm of stroke clearing the full lane width.
Knocks cartons off a sorter transfer belt at the drop point; the long reach spans the belt without extra linkage.
Drives a machine guard door through 220 mm of travel; the standard magnet lands a DMSG switch at the closed position.
Compare 0.5 MPa forces: 20 mm gives 157 N, this 25 mm gives 245.3 N, and 32 mm jumps to 402.2 N - stay at 25 mm unless the mechanism binds. A 220 mm stroke makes the 10 mm rod a long, slim lever, so guide the load on rails and push in line or seal wear shows early. Since a de-energised MA moves with whatever pushes it, hang a rod lock or pilot check valve on any gate that must hold. SDB pivot, FA flange or LB foot brackets bolt on, and the piston magnet is standard.
Quick checklist
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa they reach 343.4 N and 288.5 N. The theoretical maximum is 50 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) and rod speed 30-800 mm/s through the 1/8 inch port.
No. A plain double-acting MA coasts with the load once air drops or the valve centres, so a hanging or clamped gate will move. Add a rod lock or a pilot check valve to pin the position - the bumper pads only soften the stop, they are not a brake.
