Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 220mm 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 MAC25X220SCM
Round-body and riveted into one sealed unit, the MAC25X220SCM pairs a 25 mm bore with a 220 mm stroke and air power on both sides of the piston. It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, rising to 343.4 N at 0.7 MPa, and needle-adjustable cushions at each end take the sting out of fast stops.
The CM round-end back cover accepts pivot pins straight off the shelf, so a linkage can track the 220 mm stroke without adapter plates. Every MAC ships with the piston magnet already fitted, so a CMSG or EMSG switch snaps onto the barrel for end-of-stroke signals. For sizing, treat about 147 N as the practical working force at 0.5 MPa - roughly 60 percent of rating - which comfortably handles a 12 kg vertical pick.

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 MAC25X220SCM Is Used
Bottling lane diverter
Swings PET bottles between two lanes on a bottling line, the cushioned arrival keeping crates and guides from ringing.
Rinse-skid gate actuator
Strokes a 220 mm gate on a stainless-piped rinse skid, where a painted-steel body would rust through within months.
Drill-jig clamp
Clamps a machined housing into a drill jig with 245 N of push, the round-end pivot following a toggle linkage.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X220SCM the Right Cylinder?
Bore 25 delivers 245.3 N at 0.5 MPa; the 20 mm frame manages only 157.0 N while the 32 mm reaches 402.2 N, so scale accordingly. This cylinder holds no position when air is removed - the piston coasts freely on a centred valve - so fit a pilot check valve or rod lock where a suspended load matters. Mount on the CM round-end cover with a pivot pin, or choose FA flange, LB foot or SDB bracket hardware, and sense travel with a CMSG/DMSG/EMSG switch on the standard magnet. Guide external sliders precisely at cycle speeds up to 800 mm/s; side thrust over the 220 mm stroke bends the 10 mm rod and wears the seals.
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 MAC25X220SCM FAQ
Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air; proof pressure is 1.5 MPa (215 psi). At bore 25 the outputs are 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical ceiling of 50.0 kgf at 1.0 MPa. Ports are 1/8 inch.
No. The magnet is fitted in the piston as standard on every MAC, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel and trip at either end of the 220 mm travel without a special-order build.
