Airtac MAC Stainless Steel Mini Air Cylinder MAC32X280SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X280SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 280mm 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 MAC32X280SU
At 0.5 MPa the MAC32X280SU develops 402.2 N (about 41 kgf) on extend and 345.6 N on retract, a force class that handles clamping, ejecting and light lifting on packaging and assembly machinery. Air drives the piston both ways, and a variable air cushion at each end absorbs the shock of a fast 280 mm stroke, so you can push speed toward the 800 mm/s ceiling without hammering the covers. Keep the working load near 241 N and the cylinder stays comfortably inside its 0.15-1.0 MPa (22-145 psi) band.
The body is a stainless round barrel with aluminium covers rolled onto the tube, a riveted joint that cannot work loose, and the hard-chrome plated 12 mm rod shrugs off washdown spray and mild corrosion. A magnet is built into the piston as standard, so CMSG, DMSG or EMSG switches clip straight on for end-of-stroke signals. The U flat-end back cover bolts the cylinder flat against a machine face with no extra bracket.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X280SU Is Used
Benchtop pin press
A fixed-mounted MAC32X280SU seats dowel pins into aluminium housings on a small assembly bench, using about 240 N of its 402.2 N push at 0.5 MPa.
Carton kicker
Mounted flat against the conveyor frame by its U cover, it kicks cartons off the line at up to 800 mm/s while the end cushions soften the hit.
Sample tray ejector
In a lab automation cell the stainless barrel resists the cleaning fluids used around the tray elevator, ejecting sample racks every cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X280SU the Right Cylinder?
At 245.3 N the 25 mm bore covers half this force, and if you later need 628.3 N the 40 mm bore steps up - both share the same MA family mounting set of FA flange, LB foot or SDB pivot. Remember a plain MAC drifts when the valve centres: air pressure is what holds the piston, and a dropped supply means the rod moves, so fit a pilot check valve or rod lock if the load must stay put. Over 280 mm of travel, keep side loads off the chrome rod and guide the part externally.
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 MAC32X280SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa those rise to 563.0 N and 483.8 N. The theoretical ceiling is 82 kgf at 1.0 MPa. Port size is 1/8", the rod is 12 mm with M10x1.25 male thread, and 280 mm sits inside the 500 mm standard stroke limit for this bore.
Needle screws at both ends admit air into a variable cushion chamber - back them fully off at first run, then close gradually until the 280 mm stroke stops without knock. The U flat-end back cover presents a plain flat face, so the cylinder bolts straight to a machine plate without a bracket.
