Airtac MAC Stainless Steel Mini Air Cylinder MAC25X70SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X70SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 70mm 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 MAC25X70SCA
Air drives the piston out and back on the MAC25X70SCA, a double acting round-body mini from AirTAC with a 25 mm stainless barrel and a hard-chrome plated 10 mm rod. The aluminium covers are rolled and riveted onto the tube for a sealed body, and a variable air cushion at each end soaks up end-of-stroke shock so you can push 245.3 N at 0.5 MPa (343.4 N at 0.7 MPa) without hammering the covers.
Its CA pivot back cover provides the rear eye a swing linkage needs, pinning straight onto the machine lever. Every unit ships with a built-in magnet, so a CMSG, DMSG or EMSG switch clips onto the barrel for position signalling. The stainless shell also shrugs off washdown splash that pits painted mini cylinders, which is why damp food and packaging lines keep choosing it. For sizing, keep real work near 147 N at 0.5 MPa, roughly 60 percent of the rated push.

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 MAC25X70SCA Is Used
Carton flap tucker
A swing arm folds flaps on a case packer at up to 800 mm/s; the CA pivot hangs on the linkage while the 245 N stroke tucks glue-flapped cartons square.
Bottle line divert gate
A gate swings bottles off a filling conveyor; cushioned stops at both ends keep the swinging gate mass from banging the frame at every cycle.
Bracket drill fixture
Clamps a machined bracket during drilling; about 147 N of usable force at 0.5 MPa holds thin plate without crushing, and the CMSG switch confirms clamp-on.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X70SCA the Right Cylinder?
Compare bores before you commit: the 20 mm MAC produces about 157 N at 0.5 MPa and the 32 mm about 402 N, so the 25 mm at 245.3 N push / 206.1 N pull covers medium clamp and slide duties. When the valve centres, the piston drifts under load, so a pilot check valve or rod lock is needed wherever position must hold. The CA pivot works with SDB brackets or I and Y rod knuckles, and the 1/8 ports come in PT (blank), G or NPT thread. A 70 mm stroke is standard, with longer travels available up to 500 mm, though side loads grow with length, so guide the rod on long runs.
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 MAC25X70SCA FAQ
At 0.5 MPa supply it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures rise to 343.4 N push and 288.5 N pull. Theoretical peak at 1.0 MPa is 50 kgf. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-800 mm/s, cushioned at both ends.
The barrel is stainless steel with aluminium covers rolled on, and the rod is hard-chrome plated carbon steel, so splash and humidity do not pit it the way they attack painted minis. Needle screws give a variable air cushion at both ends; open them gradually on first run.
