Airtac MAC Stainless Steel Mini Air Cylinder MAC25X260SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X260SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 260mm 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 MAC25X260SCA
A 25 mm bore round-body mini cylinder with a riveted stainless-steel barrel, the MAC25X260SCA runs double acting - air extends and retracts the rod - with a variable air cushion at each end. At 0.5 MPa it delivers 245.3 N on extension and 206.1 N on retraction, backed by an operating band of 0.15-1.0 MPa (22-145 psi) and stroke speeds of 30-800 mm/s. The CA back cover carries a pivot pin, so linkage arms swing with the cylinder without adapter plates.
The stainless tube plus hard-chrome plated carbon-steel rod takes damp shop air, washdown spray and outdoor duty far better than painted mini bodies. For sizing, plan real work around 147 N at 0.5 MPa - 60 percent of the rated push - which still lifts about 12.5 kg vertically with a 2:1 margin. Magnet comes built in, so CMSG, DMSG or EMSG switches drop onto the barrel for end-of-stroke signals.

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 MAC25X260SCA Is Used
Carton Push-Off at a Merge
A swinging gate on the CA pin diverts cartons off a conveyor merge; 245 N at 0.5 MPa clears a 5 kg carton with ease and the 260 mm stroke reaches across the lane.
Swing Clamp on a Welding Fixture
The pivot back cover follows the clamp arm arc, so the hard-chrome rod stays unstressed through 90 degree swings on sheet-metal jigs.
Case Ejector at a Palletizer
Knocks formed cases sideways off the forming station; variable cushioning lets the ejector run near 500 mm/s without slamming the covers.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X260SCA the Right Cylinder?
Sizing neighbours: the 20 mm bore MAC manages 157 N push at 0.5 MPa and the 32 mm bore 402.2 N, so step down to save air or step up when friction and side load eat margin. Because the piston drifts the moment air is vented, add a pilot check valve or rod lock if the 260 mm stroke has to hold position under load. The CA pivot cover suits SDB brackets, while FA flange and LB foot mounts stiffen the body where needed; the built-in magnet keeps switch choice open.
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 MAC25X260SCA FAQ
At 0.5 MPa the 25 mm bore pushes 245.3 N and pulls 206.1 N; at 0.7 MPa this becomes 343.4 N push and 288.5 N pull. Theoretical maximum is 50 kgf at 1.0 MPa. Air ports are 1/8" and the rod thread is M10x1.25; operating range is 0.15-1.0 MPa (22-145 psi).
Both stroke ends carry a variable air cushion. Back the needle screws fully off before the first cycle, then close them step by step until the 30-800 mm/s motion stops without a knock at the CA cover end or the head end.
