Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 110mm 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 MAC20X110SCA
A 20 mm bore double-acting mini cylinder delivering 157 N forward and 131.9 N on return at 0.5 MPa, rising to 219.8 N and 184.7 N at 0.7 MPa, with 32 kgf of theoretical peak force. Air cushions at both ends are adjusted with needle screws, so end-of-stroke shock can be tuned out at stroke speeds up to 800 mm/s. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
Inside, a stainless round barrel pairs with a hard-chrome plated rod and riveted aluminium covers, a build that shrugs off washdown and damp plant air far better than painted mini cylinders. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel. At 157 N push, budget roughly 94 N for real work, and expect about 8 kg of vertical lift 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 MAC20X110SCA Is Used
Pivoting carton deflector
On a packaging line, the CA pivot eye pins straight into a clevis to swing a deflector rail between two chute lanes, with 157 N at 0.5 MPa enough for lightweight cartons.
Bottle ejection pusher
A filling machine can use the 110 mm stroke to push misfilled bottles off a conveyor lane; cushions soften the contact so glass is not chipped at speed.
Position feedback on a slide
With the magnet already in the piston, CMSG or DMSG switches bolt to the barrel and tell the PLC when the slide has fully extended and retracted.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SCA the Right Cylinder?
If your circuit sits between the 100.5 N of a 16 mm bore and the 245.3 N of a 25 mm bore, this 20 mm barrel fills the gap with 157 N at 0.5 MPa. The CA pivot back cover takes a clevis pin directly, no extra bracket needed; FA flange, LB foot or SDB pivot mounts can be added to the same order. Note that the rod drifts freely once air is dumped or the valve centres, so fit a pilot check valve or rod lock where loads must be held. Over a 110 mm stroke, keep side loads low to protect the 8 mm rod.
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 MAC20X110SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa those rise to 219.8 N and 184.7 N. Theoretical maximum force at 1.0 MPa is 32 kgf. Running pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and stroke speed runs 30-800 mm/s.
Yes. Needle screws at both ends meter the exhaust air; back them off for the first run, then close them gradually until the 110 mm stroke lands smoothly. The built-in magnet also lets CMSG, DMSG or EMSG switches signal end positions without a special-order piston.
