Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MAC25X75SCM
A riveted stainless round barrel and a hard-chrome plated 10 mm rod make the MAC25X75SCM a mini cylinder that shrugs off washdown and damp plant air, where painted-steel minis start to corrode. It is double acting - air drives the rod out and pulls it back - and a variable air cushion at each end lets you bleed off end-of-stroke shock by simply backing off the needle screws.
At 0.5 MPa this body pushes 245.3 N and pulls 206.1 N, inside a 0.15-1.0 MPa (22-145 psi) working window with 1.5 MPa (215 psi) proof. Keep real work near 147 N, about 60% of the rating, and it will lift roughly 12 kg vertically with a 2:1 margin. The CM round-end back cover takes a pivot pin directly, and the built-in magnet accepts CMSG, DMSG or EMSG switches without special ordering.

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 MAC25X75SCM Is Used
Packaging line pusher
A 75 mm stroke sidesteps cartons on a food conveyor, where the stainless barrel survives daily washdown and the cushion stops the box without a bang.
Fixture clamp on a drill jig
About 147 N of practical force at 0.5 MPa holds aluminium parts in a drill jig, and the CM round end pins straight to a toggle link.
Indexing with position feedback
The standard magnet drives a CMSG switch at each end of the 75 mm travel, so the PLC confirms the part is present before the next cycle starts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCM the Right Cylinder?
Between the 20 mm bore (157 N push at 0.5 MPa) and the 32 mm bore (402.2 N), this 25 mm unit sits squarely in mid-duty territory on a 75 mm stroke. The CM back cover pivots on a pin, while FA flange, LB foot or SDB pivot brackets bolt on if the frame needs a fixed base. Air porting is 1/8" and the male rod thread is M10x1.25.
When the directional valve centres or air pressure is gone, the rod simply coasts wherever the load takes it - add a rod lock or pilot check valve if the position must stick. Running anywhere in the 30-800 mm/s band, keep side load off the 10 mm rod on long overhangs.
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 MAC25X75SCM FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa, 343.4 N push and 288.5 N pull; theoretical maximum is 50 kgf at 1.0 MPa. It is double acting with a variable air cushion at both ends, runs 30-800 mm/s on air filtered to 40 um, and takes a 1/8" port with an M10x1.25 rod thread.
The rounded cover accepts a pivot pin directly, so linkages and swing arms connect without an extra bracket. If the layout later needs a fixed base, FA flange, LB foot or SDB pivot accessories fit the same 25 mm bore body, and the built-in magnet keeps switch readout available throughout.
