Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCAH 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 MAC25X80SCAH
Swing-mounted and corrosion-proofed, the MAC25X80SCAH pairs a 25 mm stainless round barrel with a CA clevis back cover and 80 mm of double-acting travel. Push is 245 N and pull 206 N at 0.5 MPa, rising to 343 N at 0.7 MPa, while the needle-adjustable cushion at each end soaks up stop shock on faster cycles. Note that the trailing H is not one of the standard MA back-cover options, so confirm its exact meaning from the datasheet before ordering.
In service, size the job to about 147 N at 0.5 MPa; vertically that is near 25 kg of lift, or roughly 12 kg once you halve for a safe margin. The two-way piston seal stores its own grease for long life, and the magnet built in as standard accepts CMSG, DMSG and EMSG switches directly on the barrel.

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 MAC25X80SCAH Is Used
Swing clamp on a weld fixture
The clevis pivot tracks the arm arc as it clamps car-door brackets; about 147 N of working force holds parts steady despite nearby weld spatter.
Flap diverter on a grain auger
A pivoting flap routes grain between two chutes; the stainless barrel shrugs off dust and damp that corrode a painted mini body within a season.
Swing stop on a rotary table
Swings into an index slot to locate a 12 kg rotary fixture, and the end cushion takes the stop impact even at full 800 mm/s cycle speed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCAH the Right Cylinder?
The 20 mm bore (157 N at 0.5 MPa) suits lighter pivoting clamps; the 32 mm bore (402 N) handles heavier swing arms. A 10 mm rod pivots on the CA cover - keep side load minimal or fit an I or Y rod knuckle to take the bending out. With air removed or the valve centred, the piston drifts freely, so add a rod lock or pilot check valve wherever a load must stay put. PT ports are 1/8", the rod thread is M10x1.25, and LB foot, FA flange and SDB pivot brackets all bolt up alongside the CA cover.
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 MAC25X80SCAH FAQ
Push at 0.5 MPa is 245.3 N and pull 206.1 N; at 0.7 MPa push reaches 343.4 N, with a 50 kgf theoretical maximum at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speeds from 30-800 mm/s are available. Two 1/8" ports and an M10x1.25 male rod thread on a 10 mm rod complete the connections.
No - the magnet is built into the piston as standard on every MAC cylinder. CMSG, DMSG or EMSG reed switches simply slide onto the stainless barrel and clamp where you want an extend or retract signal, no special-order piston or modified cylinder required.
