Airtac MAC Stainless Steel Mini Air Cylinder MAC20X35SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X35SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 35mm 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 MAC20X35SCA
A double-acting mini cylinder with a variable air cushion at both ends, MAC20X35SCA turns 0.15-1.0 MPa (22-145 psi) of filtered air into 157 N of push at 0.5 MPa over its 35 mm stroke. The CA pivot back cover provides a ready-made pin joint, so a clevis or swing link bolts straight on without an extra bracket.
The riveted stainless round barrel and 8 mm hard-chrome plated rod cope with damp or washed-down surroundings far better than painted-steel minis. Needle screws at each end let you open the cushion fully on first run and trim it in gradually, and because 157 N is the full rating, a sensible plan is about 94 N of continuous work - enough for gates, clamps and small presses. Speed range 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 MAC20X35SCA Is Used
Bottling line gate
Swing gates and deflector flaps on a 200 ml bottle line, where 157 N at 0.5 MPa and a short 35 mm throw keep lane changes crisp.
Carton tuck flap
Presses and tucks the end flap on small folding cartons at up to 800 mm/s; the variable cushion stops the flap from being hammered.
Drill jig clamp
Clamps thin aluminium sheet in a drill jig; the CA pivot eye takes the swinging link directly.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X35SCA the Right Cylinder?
At 157 N of push and 132 N of pull at 0.5 MPa, bore 20 suits light clamping and gating. Step down to a 16 mm bore (100.5 N push) for lower loads or up to a 25 mm bore (245.3 N) if the workpiece resists more. The CA pivot cover pairs naturally with a clevis; add LB foot or FA flange mounts where the body needs holding too.
Note that a plain MAC drifts once the air is removed - the cushion slows the piston but never locks it, so use a pilot check valve or rod lock for a held load. The built-in magnet is standard, so CMSG, DMSG or EMSG switches mount without a special piston.
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 MAC20X35SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 132 N; at 0.7 MPa those rise to 220 N and 185 N, and the theoretical maximum is 32 kgf at 1.0 MPa. The bore-20 port is 1/8 in, the male rod thread is M8x1.25 and the rod is 8 mm. The air cushion is adjustable at both ends.
The barrel is a stainless steel tube rolled onto aluminium covers with a stainless block - no through-bolts to loosen and no paint to chip. With the 20 um hard-chrome plated carbon-steel rod, the cylinder survives washdown spray and humid areas that rust painted mini cylinders. It is a riveted round-body design, 20 mm bore, 35 mm stroke, magnet built in.
