Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MAC20X100SCAH
A trailing H on this order code marks an option outside the standard MA suffix list, so confirm its exact meaning on the current AirTAC datasheet before ordering. The base specification is proven: 20 mm bore, 100 mm stroke, double acting with a variable air cushion, pushing 157.0 N at 0.5 MPa from a 0.15-1.0 MPa (22-145 psi) supply.
Build quality is the usual MAC recipe - riveted stainless barrel, hard-chrome plated 8 mm rod, aluminium-alloy covers - which shrugs off the condensation found near washdown tables and outdoor conveyors. The magnet is fitted as standard, ready for CMSG, DMSG or EMSG switches, and the CA rear pivot suits swinging mechanisms. Expect about 94 N of dependable working force, enough to lift 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 MAC20X100SCAH Is Used
Deflector on a bottling conveyor
Swings a guide rail across a 100 mm lane to divert PET bottles; the rear pivot tracks the arc and the cushion prevents the rail from slamming home.
Docking flag on AGV tuggers
Moves a flag into a photo-eye path to confirm charge-station docking; the standard magnet plus an EMSG switch signals both end positions to the controller.
Benchtop press for grommet insertion
Presses grommets into fabric samples with 157.0 N at 0.5 MPa; dial the cushion in for a soft touch-down that will not mar delicate cloth.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCAH the Right Cylinder?
Between the 16 mm bore (100.5 N at 0.5 MPa) and the 25 mm bore (245.3 N), the 20 mm sits at a handy mid-point for medium mini-duty linkages. Ports are 1/8" with an M8x1.25 male rod thread and PT as the standard option, cycling at 30-800 mm/s. If your mechanism pivots, the CA back cover removes the need for a separate eye bracket; FA flange or LB foot mounts cover fixed installations. Because the piston is free-floating once air is removed, add a rod lock or pilot check valve wherever the 100 mm stroke must stop and stay. Stroke lengths up to 500 mm are standard for this bore.
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 MAC20X100SCAH FAQ
At 0.5 MPa the 20 mm bore pushes 157.0 N and pulls 131.9 N; at 0.7 MPa those rise to 219.8 N and 184.7 N. The theoretical maximum is 32.0 kgf at 1.0 MPa. The H suffix on this model should be confirmed from the datasheet before you place the order.
No coating is needed for typical splash and condensation - the barrel is stainless steel and the 8 mm rod carries a 20 um hard-chrome layer. For position feedback, the built-in magnet accepts CMSG, DMSG and EMSG switches without any special-order piston.
