Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA is a genuine double acting + cushion 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. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA
Eighty millimetres of travel on a 25 mm stainless round body: the MAC25X80SCA is double acting with a variable air cushion at both ends. Push force is 245 N at 0.5 MPa (343 N at 0.7 MPa), and the riveted stainless tube with its hard-chrome plated 10 mm rod stands up to washdown and light corrosion that ruin painted minis.
Pivoting motion is built in - the CA back cover swings on a clevis pin with no adaptor required. Plan real work around 147 N at 0.5 MPa, or roughly a 12 kg vertical lift at half margin; the theoretical ceiling is 50 kgf at 1.0 MPa. A magnet comes standard in the piston, so CMSG / DMSG / EMSG switches mount without any special-order cylinder.

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.
Theoretical Output Force (Ø25mm)
| 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.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA Is Used
Jig clamp on a drill fixture
An 80 mm stroke clears the fixture for loading, then clamps steel brackets with about 147 N of usable force cycle after cycle.
Reject finger on a checkweigher
Flicks 300 g underweight packs off the belt; the dual air cushion softens the flick at both ends so no pack bounces back.
Index stop on a rotary fixture
Drops into an index slot to locate a 12 kg rotary table position; the stainless barrel tolerates coolant mist around the machine.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA the Right Cylinder?
Size both ways: the 20 mm bore covers lighter duties at 157 N (0.5 MPa), while the 32 mm bore doubles up with 402 N. When the valve centres or air is lost the rod floats freely - a pilot check valve or rod lock is the part that holds a load. Pair the CA pivot with an LB foot, FA flange or SDB bracket as the frame demands; air ports are 1/8" and the rod thread is M10x1.25, with I or Y knuckles adding a wrist if the load must swivel.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCA FAQ
Rated output at 0.5 MPa is 245.3 N pushing and 206.1 N pulling; at 0.7 MPa push climbs to 343.4 N. The theoretical maximum is 50 kgf at 1.0 MPa. The operating band is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speeds run 30-800 mm/s, and both 1/8" ports feed the same chamber set through needle-screw cushions.
Both ends carry a variable cushion controlled by needle screws. Back the screws fully off before first stroke, run the cylinder slowly, then close them gradually until end-of-stroke shock disappears at your cycle speed - anywhere in the 30-800 mm/s range.
