Airtac MAC Stainless Steel Mini Air Cylinder MAC25X30SCA
The AirTAC MAC Stainless Steel Mini Air Cylinder MAC25X30SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MAC25X30SCA
Short stroke, quick decisions: the MAC25X30SCA moves just 30 mm but does it with 245.3 N of push at 0.5 MPa behind a 25 mm piston - enough to snap a gate, clamp or diverter shut in milliseconds. The action is double acting, and a variable air cushion at each end absorbs the snap so the pivot pin and bracket are not hammered over millions of cycles. AirTAC builds the body as a riveted stainless round barrel with aluminium-alloy covers, and the hard-chrome plated rod (20 um) keeps its finish in wet or dusty plant air. Ports are 1/8" and the rod thread is M10x1.25.
The CA pivot back cover is the headline here: mount it on a pin and the whole cylinder swings with a lever or clamp arm, no extra clevis bracket needed. With the magnet fitted as standard, a CMSG, DMSG or EMSG switch reads end positions straight off the barrel. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.

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 MAC25X30SCA Is Used
Swing clamp on a welding jig
Clamps bracket plates on an automotive spot-welding jig; the CA pivot cover lets the cylinder rock with the clamp arm through its 30 mm travel.
Flap gate on a seed hopper
Snaps a gravity flap open and closed on a seed-treater hopper; 245 N of push at 0.5 MPa overcomes light product bridging.
Print carriage stop
Poses a registration stop against a moving print carriage; the built-in magnet and a CMSG switch confirm the stop is engaged.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X30SCA the Right Cylinder?
Two bores bracket this one: a 20 mm cylinder of the same series pushes 157 N at 0.5 MPa for lighter snap actions, while the 32 mm pushes 402.2 N when a clamp needs real bite. Note that a short-stroke double-acting cylinder like this holds nothing on its own - if the valve is centred the arm it drives can be pushed back off position, so a rod lock or pilot check valve is needed wherever that matters. Order FA flange, LB foot or SDB pivot bracket alongside the CA pivot cover if the frame needs a fixed mount too. At 30 mm of stroke side load is far less of a worry than on long strokes, but keep the pivot pin free to swing and the arc clear of obstruction.
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 MAC25X30SCA FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa. At 0.7 MPa the push reaches 343.4 N, and the theoretical force ceiling is 50 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure and cycles at 30-800 mm/s.
The pivot eye on the CA cover mounts on a pin so the cylinder can swing with a lever, clamp or flap - typical for short kick and clamp motions. Combined with the standard built-in magnet for CMSG, DMSG or EMSG switches, one short cylinder delivers the motion and the position signal in a riveted stainless body.
