Airtac MAC Stainless Steel Mini Air Cylinder MAC20X5SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X5SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 5mm 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 MAC20X5SCA
A 5 mm stroke with a pivoting CA back cover, the MAC20X5SCA is a double-acting mini cylinder whose variable air cushion tames end-of-stroke shock at both ends. At 0.5 MPa it pushes 157 N and pulls 131.9 N, climbing to 219.8 N at 0.7 MPa; 1.0 MPa gives a theoretical 32 kgf. The pivot eye lets the cylinder swing with a linkage instead of fighting it sideways.
The stainless barrel and hard-chrome plated rod shrug off washdown and humid air, an edge over painted minis in food plants. The magnet is standard, so CMSG, DMSG or EMSG switches mount with no special piston.

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 MAC20X5SCA Is Used
Guard-door latch
Snaps a sliding guard latch closed on a small press; the 5 mm throw suits a hook latch and 94 N of working force keeps it seated.
Assembly ejector
Kicks a finished bushing out of a press die; 157 N push at 0.5 MPa clears light interference fits without marking the part.
Switch-checked go/no-go pin
Extends a checking pin in an inspection fixture; the standard magnet drives an EMSG switch to confirm full extension each cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X5SCA the Right Cylinder?
A 16 mm MAC gives 100.5 N at 0.5 MPa if your load is lighter; a 25 mm bore offers 245.3 N for heavier clamps. This 5 mm stroke suits short eject or latch moves, not long travels. When supply air drops or the valve centres, the rod moves freely - a plain MAC does not lock its load - so fit a pilot check valve or rod lock if position must persist. The CA pivot eye suits swinging linkages; FA flange, LB foot and SDB pivot cover fixed or pivoted frames, and the standard magnet pairs with DMSG or EMSG switches.
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 MAC20X5SCA FAQ
Double acting with a variable air cushion at both ends: 157.0 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, and a theoretical 32 kgf at 1.0 MPa. Supply pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C, with 1/8" ports on the 20 mm bore.
The pivot eye lets the cylinder rotate with the mechanism, so side loads on the 8 mm rod stay low in linkages and latch arms even over a 5 mm travel. Combined with the cushion screws, short-kick moves stay quiet at both ends. The built-in magnet is standard equipment, so CMSG or DMSG switches clamp on for end-position signals with no extra ordering step.
