Airtac MAC Stainless Steel Mini Air Cylinder MAC25X330SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X330SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 330mm 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 MAC25X330SCA
Where a swing arm, gate or linkage needs a long pull, the CA pivot back cover on this 25 mm bore cylinder pins straight into the machine linkage with no fabricated bracket. It extends with 245.3 N and retracts with 206.1 N at 0.5 MPa (72 psi), double acting and cushioned at each end across the full 330 mm stroke.
The stainless barrel resists rust in damp or outdoor plant air, while the 20 um hard-chrome rod keeps the long sealing path smooth. Since the magnet is factory-fitted, CMSG / DMSG / EMSG switches report both ends of travel. For sizing, treat roughly 147 N at 0.5 MPa as the practical working force, close to lifting 12 kg vertically with a 2:1 reserve.

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 MAC25X330SCA Is Used
Mixing-vessel lid swing
Lifts and swings a 12 kg inspection lid open on a pilot line without a separate hinge cylinder.
Checkweigher reject arm
Sweeps off-weight packs 330 mm sideways into a reject chute, cushioned at both stops.
Pallet infeed guide
Swings a guide rail to steer cartons into a lane at cycle speeds up to 800 mm/s.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X330SCA the Right Cylinder?
If 245.3 N of push falls short, a 32 mm bore delivers 402.2 N at 0.5 MPa; if it is generous, the 20 mm bore at 157.0 N saves compressed air. Long strokes amplify side load, so hang the load on a guide or use an I or Y rod knuckle instead of bending the 10 mm rod. The CA pivot pairs naturally with an SDB pivot bracket at the front, while an FA flange or LB foot suits rigid mounting on the 1/8 inch PT ports. A de-energised valve leaves the piston free to move, so a rod lock or pilot check valve is the way to park a load.
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 MAC25X330SCA FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa, 343.4 N push and 288.5 N pull; 50 kgf theoretical peak at 1.0 MPa. Supply is 0.15-1.0 MPa (22-145 psi) of 40 um filtered air, speed 30-800 mm/s.
It turns the rear cover into a clevis-style pivot pin so the cylinder can articulate with a swing arm or linkage; add an SDB pivot bracket at the front or an I / Y knuckle at the rod. Every variant keeps the standard piston magnet for CMSG, DMSG and EMSG switches.
