Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MAC25X75SCA
Seventy-five millimetres of travel and a pivoting rear eye make the MAC25X75SCA a natural fit for rotary levers and swing clamps. This double acting AirTAC mini runs on a 25 mm bore, pushing 245.3 N and pulling 206.1 N at 0.5 MPa (343.4 N push at 0.7 MPa), with needle-screw air cushions at both ends that you open gradually on first run. Construction is a stainless tube with aluminium covers rolled and riveted in place for one sealed body.
The CA back cover carries the pivot pin itself, so the cylinder hangs on your linkage with nothing bolted in between. A magnet sits in the piston on every unit, letting CMSG or DMSG switches report position straight away. Plan workloads around 147 N at 0.5 MPa and the cushion plus chrome rod will carry years of fast 30-800 mm/s cycling, even in humid plants where the stainless shell stays clean.

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 MAC25X75SCA Is Used
Index lever on rotary table
A pivoting lever indexes parts on a rotary table; the CA eye rides the lever pin through every 75 mm sweep without an adapter block.
Fill nozzle press
Presses a filler nozzle onto pouches; 245.3 N extend force at 0.5 MPa seats the nozzle while the cushions soften the moment of contact.
Battery bay latch actuator
Swings the latch on a forklift battery bay; the corrosion-free stainless body copes with acid-fume air in the charging room.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCA the Right Cylinder?
Bracket the choice by force: a 20 mm bore yields roughly 157 N at 0.5 MPa while the 32 mm jumps to 402 N, placing this 25 mm at 245.3 N push / 206.1 N pull for mid-weight tooling. If the load must stay put with air off, note that a standard MAC lets the piston drift; a pilot check valve or rod lock does that job instead. The rear pivot eye pairs with SDB or LB brackets, I and Y knuckles, and PT / G / NPT thread choices on the 1/8 ports. This 75 mm travel sits well inside the 500 mm standard range, but keep side load off the 10 mm chrome rod on longer travels.
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 MAC25X75SCA FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical maximum at 1.0 MPa: 50 kgf. Supply pressure runs 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s, with a variable air cushion at both ends.
The CA back cover has the pivot built into the rear cover itself, so the cylinder pins directly to your linkage. For foot or flange fixing instead, FA flange, LB foot and SDB pivot brackets are ordering options, plus I and Y rod knuckles.
