Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MAC25X150SCAH
Where a fixture needs just past 140 mm of travel, the MAC25X150SCAH delivers 150 mm from a 25 mm bore while staying slender enough for crowded machine frames. The riveted stainless barrel and hard-chrome plated rod handle splash, chips and outdoor air without the rust that kills painted-steel minis. Double acting with variable air cushion at both ends, it makes 245.3 N forward and 206.1 N back at 0.5 MPa.
That cushion means you can chase speeds up to 800 mm/s or haul heavier parts without pounding the aluminium covers. The magnet is built in as standard, so CMSG / DMSG / EMSG switches snap on for position feedback. Treat 147 N as the practical working force - roughly a 12 kg vertical lift at 2:1 - and run between 0.15-1.0 MPa (22-145 psi) and -20 to +70 C.

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 MAC25X150SCAH Is Used
Tote stopper
A 245 N push holds back or releases rolling totes at a picking lane, and 150 mm of travel clears the tote width fully before the line resumes.
Dust gate slide
The 150 mm stroke drives a sliding dust gate under a hopper discharge; the air cushion tames the slam as the gate seats into its frame.
Checkweigher reject pusher
Working around 147 N, the cylinder knuckles mis-weighted packs sideways off a checkweigher belt into a reject bin, stroke end after stroke end.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCAH the Right Cylinder?
The trailing H in this code marks a suffix option - confirm its exact scope from the datasheet before ordering. For sizing, the 20 mm bore tops out at 157 N of push at 0.5 MPa while the 32 mm bore reaches 402.2 N, bracketing this 25 mm model's 245.3 N. No air means no holding: an unpowered MAC rod can be pushed around by the load, so specify a rod lock or pilot-operated check valve whenever position must survive a power drop. The CA pivot cover accepts linkage directly, and FA flange, LB foot or SDB brackets handle fixed mounting if the H option does not already cover it.
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 MAC25X150SCAH FAQ
Push at 0.5 MPa is 245.3 N, pull 206.1 N; raise supply to 0.7 MPa and push hits 343.4 N with pull at 288.5 N; the theoretical maximum at 1.0 MPa is 50 kgf. Ports are 1/8", the rod thread is M10x1.25, and pressure spans 0.15-1.0 MPa (22-145 psi).
The barrel is stainless steel and the 10 mm rod is hard-chrome plated to about 20 um, so splash, condensation and occasional hose-down are non-issues compared with painted minis. Covers are aluminium alloy, ports are 1/8", and the fluid should be air filtered to 40 um.
