Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MAC25X50SCM
The MAC25X50SCM pairs a 25 mm bore with a 50 mm stroke in AirTAC's round-body MA family. Double acting on both strokes with a variable air cushion at each end, it pushes 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s.
Its stainless barrel and hard-chrome plated rod (20 um) shrug off washdown and damp plant air better than painted-steel minis. The CM round-end back cover gives a clean fixed or pivoted pick-up point without added brackets. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on for end-of-stroke sensing. In practice, plan work around 147 N at 0.5 MPa - roughly 60% of rating - which is enough to cycle a 12 kg part vertically with margin.

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 MAC25X50SCM Is Used
PCB connector indexing
On a 50 mm stroke, the 245.3 N push at 0.5 MPa snaps connector housings into place on an electronics assembly line, while the cushion keeps the return from hammering the fixture.
Drilling jig clamp
A 147 N working clamp (60% of the 0.5 MPa rating) holds small aluminium brackets against a drill bushing; the stainless barrel tolerates cutting-fluid mist.
Food-line sorting gate
The CM back cover pins a deflector gate that kicks snack packs between lanes, and the washdown-friendly stainless body survives daily hose-down.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCM the Right Cylinder?
If 245.3 N at 0.5 MPa is more than the job needs, the bore 20 MAC delivers 157.0 N; when the load climbs past 400 N, step up to bore 32 at 402.2 N. Note the MAC does not hold position when air drops - the piston drifts - so add a pilot check valve or rod lock for loads that must stay put. The built-in magnet works with CMSG/DMSG/EMSG switches, and FA flange, LB foot or SDB pivot brackets bolt on if the CM back cover alone does not suit the mount.
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 MAC25X50SCM FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. Theoretical maximum is 50 kgf at 1.0 MPa. The rod is 10 mm with an M10x1.25 male thread and the port is 1/8".
The CM round-end cover leaves a compact machined face for direct bolting or a pivot pin. The adjustable air cushion at both ends lets you bleed off end-of-stroke shock - back the needle screws out on first run, then close them gradually until fast cycling stops slamming the covers.
