Airtac MAC Stainless Steel Mini Air Cylinder MAC25X40SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X40SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 40mm 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 MAC25X40SCA
A 25 mm bore with a short 40 mm stroke and a CA pivot eye at the rear cover, the MAC25X40SCA is double acting, so air extends the rod and air returns it, with a variable air cushion at each end. At 0.5 MPa it delivers 245 N of push and 206 N of pull, rising to 343 N at 0.7 MPa.
Its rolled stainless-steel barrel and hard-chrome plated rod stand up to humidity and periodic washdown where painted minis rust. Size on roughly 147 N of usable force at 0.5 MPa rather than the headline rating, and note the piston magnet is standard, so CMSG, DMSG or EMSG switches mount without any special build.

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 MAC25X40SCA Is Used
Diverter pusher on a carton lane
A 40 mm kick of 245 N at 0.5 MPa swings cartons off a roller diverter; the pivot back cover mounts to a swinging linkage while the air cushion stops the push quietly at full extension.
Pivot clamp on a welding fixture
The CA eye at the rear lets the cylinder rotate into a toggle clamp position; at 147 N of practical working force it holds sheet-metal parts in jigs without marking them.
Sample lift in a lab auto-sampler
Short 40 mm steps raise vials between stations; the stainless barrel tolerates routine wipe-down with solvents, and the built-in magnet triggers a CMSG switch at each end of travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X40SCA the Right Cylinder?
Size down to the MAC20X40 if your load is light (157 N push at 0.5 MPa) or step up to the MAC32X40 for 402 N. Because the bore is 25 mm, ports are 1/8 in and the male rod thread is M10x1.25. A plain MAC will drift if air is lost or the valve centres, so fit a pilot check valve or rod lock when a load must stay put. The CA pivot cover plus an LB foot or SDB pivot bracket covers most frame builds, and the magnet is already in the piston for CMSG / DMSG / EMSG switches.
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 MAC25X40SCA FAQ
At 0.5 MPa it pushes 245 N (245.3 N exactly) and pulls 206 N; at 0.7 MPa push is 343 N and pull 289 N. Theoretical maximum at 1.0 MPa is 50 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The CA cover provides a pivot eye at the rear, so it pairs naturally with an SDB pivot bracket or a floating joint at the rod end. FA flange and LB foot options handle fixed mounting, and I or Y rod knuckles adapt the front. The riveted round barrel keeps the whole assembly compact without loose clamping hardware.
