Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 25mm stroke, 1/4" 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 MAC50X25SCA
Short travel, heavy push: with only 25 mm of stroke the MAC50X25SCA still delivers the full Dia 50 force class - 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa - making it a compact clamp or ejector for tight machine envelopes. The riveted stainless barrel and chrome-plated rod handle damp plant air without the flaking paint you get on painted competitors.
Both ends carry a variable air cushion, so even a 25 mm hit near 800 mm/s can be softened to protect the fixture. About 589 N of that rating is a sensible working force, equal to lifting a 50 kg part vertically at a 2:1 margin. The CA pivot back cover bolts straight to a clevis, and the standard piston magnet accepts CMSG, DMSG or EMSG switches. Rated 0.15-1.0 MPa (22-145 psi).

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X25SCA Is Used
Pneumatic clamp jaw
A 25 mm pinch stroke clamps machined housings in a VMC fixture with 981.3 N at 0.5 MPa - full bore force delivered from a compact round body.
Index pin actuator
Drives a locking pin into a rotary table bore; the short stroke keeps cycle time under a second even at moderate speeds, cushioned before seat.
Die knock-out ejector
Knocks a formed part out of a shallow die, with the cushioned stroke end stopping the knock-out plate before it scars the finished surface.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCA the Right Cylinder?
For a 25 mm task the 40 mm bore offers 628.3 N at 0.5 MPa and the 63 mm bore 1557.9 N; take this 50 mm bore when you need 981.3 N in a short envelope. If cushioning proves unnecessary on such short travel, the plain MA bumper version is the simpler relative - keep the MAC when end-of-stroke damping matters. There is no spring return or lock: de-energise the valve and the rod floats, so use a rod lock or check valve where the clamp must stay closed. The CA pivot pairs with a clevis, while FA flange / LB foot / SDB mounts plus the built-in CMSG / DMSG / EMSG magnet complete the fit-out.
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 MAC50X25SCA FAQ
At 0.5 MPa: 981.3 N push and 880.8 N pull. At 0.7 MPa: 1373.8 N push. Theoretical maximum: 200.1 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) over a 25 mm stroke at 30-800 mm/s.
It will not - there is no spring or mechanical lock, and the piston drifts freely when pressure is lost. For clamping that must survive an air failure, add a pilot check valve or a rod-lock cylinder; the CA pivot back cover here is about connection geometry, not locking.
