The AirTAC Airtac MA Mini Cylinders MA25X80SCA is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 80mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The CA pivot back cover on this 25 mm MA cylinder lets the body swing on a pin or clevis, absorbing small misalignment across the 80 mm stroke. Double acting with fixed bumper pads, it develops 245.3 N of push and 206.1 N of pull at 0.5 MPa (22-145 psi), reaching 343.4 N at 0.7 MPa, with speeds of 30-800 mm/s.
The high-precision stainless barrel and hard-chrome plated rod stand up to humid, washed or outdoor surroundings better than painted minis, and the rolled covers keep the round body narrow. With the magnet fitted as standard, a CMSG, DMSG or EMSG switch reads end or mid positions straight away. In practice treat 245.3 N as the ceiling: plan the task at roughly 147 N, or expect around 12 kg of vertical lift with a 2:1 safety 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.
| 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.
Tilts the lid of a small curing oven, hinged at the CA pivot so thermal growth does not side-load the rod.
Pushes dough trays onto a reject lane at a conveyor corner, running through flour-dust-laden air without trouble.
Drives the lever on a manual-bypass valve, where the pivot cover replaces a fabricated mounting bracket.
Pick this over the 157 N MA20 when the job needs a pivoting mount and a longer reach, or step up to the 402.2 N MA32 once side loads appear; the 80 mm stroke stays well inside the 500 mm standard limit. Over that reach, guide the load externally - the slim 10 mm chrome rod is not meant to take bending. The SDB pivot bracket, FA flange or LB foot can be added to the CA cover, and the standard magnet keeps CMSG sensing available at any position. If a centred valve would let the load coast, fit a rod lock or pilot check valve in the circuit.
Quick checklist
At 0.5 MPa this 25 mm bore gives 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull; theoretical peak 50 kgf at 1.0 MPa. Air ports are 1/8", the rod is 10 mm with an M10x1.25 thread, and 80 mm sits well inside the 500 mm standard stroke for this bore.
CA means a pivot eye on the rear cover: mount the cylinder on a pin or clevis and small misalignment across the 80 mm stroke is taken up by the swing, saving you a fabricated bracket. Flat-end U and round-end CM covers are the fixed-mount alternatives, with FA flange, LB foot and SDB pivot accessories to match.
