Airtac MAC Stainless Steel Mini Air Cylinder MAC20X225SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X225SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 225mm 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 MAC20X225SCM
AirTAC's MAC20X225SCM is a double acting mini cylinder with a variable air cushion at each end, built on the 20 mm bore. Running on 0.15-1.0 MPa (22-145 psi) of filtered air, it pushes 157 N and pulls 131.9 N at 0.5 MPa, rising to 219.8 N push at 0.7 MPa. Its CM round-end back cover gives you a ready-made pivot without buying a separate bracket.
The body is a high-precision stainless-steel barrel with aluminium-alloy covers rolled on, plus a hard-chrome plated 8 mm rod that tolerates damp and washdown corners that would blister a painted mini cylinder. Because the magnet comes as standard, CMSG / DMSG / EMSG switches drop straight on for end-of-stroke signalling. For real-world sizing, treat about 94 N as the practical working force at 0.5 MPa; that equals lifting roughly 8 kg vertically with a 2:1 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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X225SCM Is Used
Rinse head lift on a bottling monobloc
The 225 mm stroke lifts spray heads clear of bottle necks between cycles; the stainless barrel and chrome rod handle the wet, caustic rinse zone, and the about-8 kg vertical margin covers the head assembly.
Carton push-off at a conveyor transfer
With 157 N of push at 0.5 MPa the cylinder nudges small cartons off a crossover belt, while the variable cushion stops the ram hammering against the housing at end of stroke.
Nozzle retract in a washdown cabinet
A CM round-end pivot lets the rod swing into line with a tilt-mounted spray nozzle, and the built-in magnet feeds a CMSG switch to confirm the nozzle is fully retracted.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X225SCM the Right Cylinder?
If 157 N at 0.5 MPa is more than the job needs, step down to the 16 mm bore of the MAC series, which pushes 100.5 N; if the load stalls, the 25 mm bore lifts output to 245.3 N at the same pressure. Ports on this bore are 1/8" with an M8x1.25 male rod thread, and speeds of 30-800 mm/s are typical. On a 225 mm stroke keep side load low or guide the load externally so the 8 mm rod is not bent. Note the piston drifts if air is lost - add a rod lock or pilot check valve if the load must stay put. Add FA flange, LB foot or SDB pivot hardware alongside the CM round-end cover as the machine layout demands.
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 MAC20X225SCM FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa those figures become 219.8 N push and 184.7 N pull. The theoretical maximum at 1.0 MPa is 32 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
Yes. The barrel is stainless steel and the 8 mm rod is hard-chrome plated carbon steel, so splashes, humidity and routine washdown do not attack it the way they would a painted-steel mini cylinder. Feed it air filtered to 40 um.
