Airtac MAC Stainless Steel Mini Air Cylinder MAC20X350SCALB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X350SCALB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 350mm 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 MAC20X350SCALB
A 350 mm reach on a bore 20 barrel, this AirTAC MAC cylinder pushes 157 N at 0.5 MPa and pulls 131.9 N on the return, double acting on both strokes. Air runs at 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s, with a variable air cushion at each end to soften the landings.
The riveted stainless barrel and hard-chrome steel rod shrug off mild corrosion and washdown better than painted minis, so damp food or outdoor cells are safe ground. Every unit carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip on without a special piston. Keep real duty near 94 N at 0.5 MPa, or trust it to lift about 8 kg vertically 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 MAC20X350SCALB Is Used
Bottle rejector arm
A 350 mm arm sweeps off-spec bottles off a beverage conveyor; the cushioned stops keep the glass calm at speed.
Small tray lift
Lifts about 8 kg trays vertically between packing shelves, with the magnet signalling top and bottom via a DMSG switch.
Glue head travel
Carries a glue nozzle across plywood panels in a small joinery cell; the stainless barrel takes adhesive mist and wipe-down.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X350SCALB the Right Cylinder?
Size both ways: a bore 16 MAC delivers 100.5 N at 0.5 MPa and a bore 25 lifts that to 245.3 N, so 20 mm sits squarely in light-to-medium duty. Note that a plain MAC drifts when air is lost - the cushion eases shock but is not a lock, so add a rod lock or pilot check valve for held loads. The CA pivot back cover pairs with the LB foot to cover swinging and fixed points, and at 350 mm keep side loads low and guide the rod if the load overhangs.
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 MAC20X350SCALB 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. The theoretical ceiling is 32 kgf at 1.0 MPa. Port is 1/8", rod is 8 mm with an M8x1.25 male thread, and the 350 mm stroke sits inside the 500 mm standard range for this bore.
No - the magnet is built into the piston as standard on the MA family, so CMSG, DMSG and EMSG reed or Hall switches mount straight onto the barrel. The variable air cushion at both ends is adjusted with the needle screws; back them off at first run and close gradually until end-of-stroke shock disappears.
