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. In real work expect about 94 N of usable push at 0.5 MPa rather than the full 157 N; in lift terms that 157 N equals roughly 16 kg, so with a 2:1 margin it lifts about 8 kg vertically. 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.
