Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 250mm 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 MAC25X250SCM
Air drives the piston both ways on this MAC25X250SCM, with a variable cushion at each end you can tune to kill end-of-stroke shock, so faster cycles or heavier moves stop clean instead of hammering the covers. At 0.5 MPa the 25 mm bore generates 245.3 N of push and 206.1 N of pull, and the rolled stainless barrel with its hard-chrome rod shrugs off moisture that pits painted mini cylinders.
The CM round-end back cover presents a clean fixing face for pivoting installations without adapter plates. Keep the working push near 147 N at 0.5 MPa and the cylinder will reward you with long seal life; vertically that is about 12 kg lifted with a 2:1 margin. The magnet comes fitted as standard - CMSG, DMSG and EMSG switches clip straight onto the barrel.

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 MAC25X250SCM Is Used
Chip drawer closer
Pushing swarf drawers home on a CNC turning centre, 245 N of push at 0.5 MPa seating even heavy drawers.
Palletiser layer squaring
Squaring cases against a backstop on a low-speed palletiser layer table before the next row drops.
Oven hood lift
Raising a hinged curing-oven hood with about 12 kg of practical vertical lift capability at a 2:1 margin.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SCM the Right Cylinder?
Lighter loads may suit the 20 mm bore at 157.0 N push and 0.5 MPa; heavier work points to the 32 mm bore and its 402.2 N push. Mounting is flexible - SDB pivot brackets, LB feet or an FA flange bolt straight on, and the CM round end suits rod-eye linkages. Air-off holding is not part of the design: centre the valve with supply removed and the rod will creep, so add a pilot check valve or rod lock for parked loads. The 250 mm stroke on a 10 mm rod also argues for guiding lateral force elsewhere.
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 MAC25X250SCM FAQ
Count on 245.3 N push and 206.1 N pull at 0.5 MPa, climbing to 343.4 N and 288.5 N at 0.7 MPa; the 1.0 MPa theoretical ceiling is roughly 50 kgf. Bore is 25 mm, rod 10 mm, ports 1/8 inch, and running speed spans 30-800 mm/s.
Back both cushion needle screws fully open before start-up, cycle slowly, then close them a turn at a time until end-of-stroke bounce disappears. The supply can run anywhere from 0.15-1.0 MPa (22-145 psi) with air filtered to 40 um, and the cushion is adjustable at both ends, not a fixed bumper.
