Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 65mm 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 MAC25X65SCA
With a 25 mm bore pushing 245 N at 0.5 MPa (206 N on retraction), the MAC25X65SCA handles clamp-and-position work on compact fixtures without stepping up to a 32 mm barrel. The cylinder is double acting with a variable air cushion at both ends, so end-of-stroke shock can be tuned out with the needle screws and cycles can run faster or carry heavier tooling.
AirTAC rolls the aluminium covers and a stainless block onto the high-precision stainless barrel, and the hard-chrome plated 10 mm rod shrugs off mild corrosion in damp or washdown areas. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on without a special piston. At 245 N of push, keep real working loads near 147 N at 0.5 MPa - about the force needed to clamp a small aluminium die or lift roughly 12 kg vertically with margin.

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 MAC25X65SCA Is Used
Small parts clamping on assembly fixtures
245 N at 0.5 MPa is enough to clamp brackets or housings in drilling and riveting fixtures on small-appliance assembly lines.
Push-off on packaging conveyors
The 65 mm stroke kicks cartons or trays off a 300 mm wide transfer conveyor, with the air cushion absorbing the stop at each end.
Position detection on index tables
The standard magnet works with CMSG switches to confirm full extension of a rotary index table lock before the cycle starts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCA the Right Cylinder?
Step down to a MAC20X65 (157 N push at 0.5 MPa) for lighter tasks, or step up to MAC32X65 (402 N) when the load grows. The CA pivot back cover on this model takes a pivoting mount without extra brackets; FA flange and LB foot brackets are also available. A MAC does not hold position when air is lost - the rod drifts - so fit a pilot check valve or rod lock if the 65 mm stroke must stay put under load. 65 mm sits well inside the 500 mm standard stroke limit for this bore.
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 MAC25X65SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N and pull to 288.5 N. The theoretical maximum for this 25 mm bore is 50.0 kgf at 1.0 MPa. Air pressure range is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
Air ports are 1/8" (bore 25), the rod is 10 mm with an M10x1.25 male thread, and thread options are PT (blank), G or NPT. The CA pivot back cover accepts a pivoting mount directly; FA flange, LB foot and SDB pivot brackets plus I and Y rod knuckles are available.
