Airtac MAC Stainless Steel Mini Air Cylinder MAC20X10SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X10SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MAC20X10SU
Ten millimetres, one flat face, 157 newtons. The MAC20X10SU is AirTAC's cushioned mini for quick short moves: double acting, 30-800 mm/s, with an adjustable air cushion at both ends so a 10 mm snap never hammers the covers. Its stainless rolled barrel and 8 mm hard-chrome rod handle splash and rinsing that would swell a painted-aluminium body, which is why these cylinders show up near coolants and rinse stations.
The U flat-end back cover bolts flat against plates and brackets without adaptors, and the magnet inside is standard - CMSG, DMSG and EMSG switches all read it. Plan the job around about 94 N of continuous work at 0.5 MPa (22-145 psi); that headroom lets the cylinder hold full force through pressure dips instead of stalling at low supply.

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 MAC20X10SU Is Used
CNC fixture pin
Pops a locating pin 10 mm into a jig's bored bush between cycles; cushioned entry stops the pin from bouncing.
Presence flag on a rinse tunnel
Kicks a stainless flag into the bottle stream for a photo-eye count, standing up to daily caustic washdown.
Small clamp on a glue head
Pinches a glue-line nozzle closed during idle, holding about 94 N of real clamping force at 0.5 MPa.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X10SU the Right Cylinder?
Frame it against its neighbours: a 16 mm bore delivers 100.5 N push at 0.5 MPa for feather-light pins, while a 25 mm bore gives 245.3 N where a clamp needs real bite. A 10 mm stroke barely exposes the rod, so side load is rarely an issue, but square up the flat-end mounting to keep the seal tracks true. If the load must stay put when air drops, this double-acting MAC will drift - fit a rod lock or pilot check valve to hold position.
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 MAC20X10SU FAQ
Push 157 N and pull 132 N at 0.5 MPa; push 220 N and pull 185 N at 0.7 MPa; 32 kgf theoretical maximum at 1.0 MPa. Stroke 10 mm, bore 20 mm, 8 mm rod with M8x1.25 thread, 1/8" port, 0.15-1.0 MPa (22-145 psi) working pressure.
Yes - the variable air cushion works at both ends even on the shortest strokes, tuned via needle screws on the covers. Start with them open and close them slowly until the 30-800 mm/s motion lands softly.
