Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MAC20X125SCAH
With a 125 mm stroke on a 20 mm bore, the MAC20X125SCAH drives longer reach in AirTAC's riveted mini format - a stainless round barrel with a hard-chrome rod that shrugs off moisture, mist and mild washdown where painted bodies would corrode. Double acting on both strokes, it cushions variably at each end, so faster cycles need not hammer the covers.
Force at 0.5 MPa is 157 N out and 132 N back - enough to lift about 8 kg vertically once you keep a 2:1 margin - and the push climbs to 220 N at 0.7 MPa. The built-in magnet is standard kit, so CMSG, DMSG or EMSG switches drop on for position feedback. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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 MAC20X125SCAH Is Used
Carton kicker at a conveyor junction
Kicks small parcels across a belt with 157 N at 0.5 MPa while the cushion softens each arrival at the far rail.
Dosing probe on a benchtop filler
Drives a fill nozzle down 125 mm into vials, with switch feedback from the standard magnet timing each stroke.
Slide opening on a machine guard
Pushes a sliding guard panel open at cycle start; the hard-chrome rod stands up to coolant splash along the full travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCAH the Right Cylinder?
Compared side by side, the 16 mm bore offers 100 N at 0.5 MPa and the 25 mm bore 245 N, so this 20 mm sits mid-range for light pushes and probes. Remember the MAC is double acting only: with no air or a centred valve the rod floats, so use a rod lock or pilot check valve where a load must stay put. The CA pivot cover takes a swinging mount directly; the trailing H in the code marks a build option, so confirm the exact variant from the datasheet. Ports are 1/8" on this bore with an M8x1.25 male rod thread.
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 MAC20X125SCAH FAQ
At 0.5 MPa: 157 N push, 132 N pull. At 0.7 MPa: 220 N push, 185 N pull. Theoretical maximum: 32 kgf. It runs on 0.15-1.0 MPa (22-145 psi), is proof tested to 1.5 MPa (215 psi), and both cushion needles are adjustable.
The rolled stainless tube and 20 um hard-chrome rod resist rust in damp, food-wash or outdoor positions, while the riveted aluminium covers keep the barrel sealed without periodic re-tightening.
