Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 5mm 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 MAC25X5SCA
Short travel, big force: the MAC25X5SCA covers just 5 mm, yet the 25 mm double-acting bore still develops 245 N pushing and 206 N retracting at 0.5 MPa - 343 N and 288 N respectively at 0.7 MPa, peaking at 50 kgf. AirTAC builds it as a riveted round-body mini with a variable air cushion on each end and a 1/8" port.
The CA pivot back cover is the point of this variant: the eye swings with the load, so linkage arms and tilt levers connect without extra brackets. Inside, the stainless barrel and hard-chrome plated rod hold accuracy in damp or washdown spots, while the standard piston magnet feeds CMSG, DMSG or EMSG switches. Practically, plan around 147 N of working force at 0.5 MPa; straight vertical that equals about 25 kg lifted, or 12 kg if you halve it for a 2:1 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.
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 MAC25X5SCA Is Used
Jig pin ejector
Kicks finished dowel pins clear of drill jigs - 5 mm of travel, 245 N of push, no bounce thanks to the cushion.
Sample kick lever
Tilts a small lab sampler arm through 5 mm; the CA pivot eye follows the lever arc directly.
Stop pin indexing
Pop-in pop-out indexing pins on rotary tables, retracting fast at up to 800 mm/s between cycles.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SCA the Right Cylinder?
Five millimetres is the MAC family's shortest step, so think in terms of nudges, ejects and fine clamps rather than reach. If 245 N at 0.5 MPa is more than the job needs, a MAC20X5SCA (157 N) saves air; a MAC32X5SCA (402 N) suits stiff eject punches. Because the base cylinder holds nothing when the valve centres - it simply drifts - use a pilot check valve on any 5 mm stroke that must stay put under load. FA flange, LB foot or SDB pivot brackets pair with the CA cover, and the standard magnet keeps switching simple.
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 MAC25X5SCA FAQ
At 0.5 MPa: 245 N push, 206 N pull. At 0.7 MPa: 343 N push, 288 N pull. Theoretical maximum 50 kgf at 1.0 MPa. It is double acting with variable air cushions, works on 0.15-1.0 MPa (22-145 psi) and runs 30-800 mm/s.
The CA cover ends in a pivot eye, so the cylinder swings with linkages instead of being bolted rigidly - useful on tilt levers and clamp arms. Fixed frames can still use FA flange or LB foot brackets, and the standard magnet keeps CMSG or DMSG switch mounting unaffected.
