Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 55mm 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 MAC32X55SCA
With a 32 mm bore pushing 402 N at 0.5 MPa, the MAC32X55SCA is AirTAC's round-body stainless mini cylinder for mid-range clamping and positioning. Double acting with a variable air cushion at both ends, it runs 30-800 mm/s over a 55 mm stroke while the needle screws let you dial out end-of-stroke shock, so faster cycles stay gentle on the covers.
The riveted stainless barrel and hard-chrome plated 20 um rod handle washdown and damp workshops far better than painted-steel minis, and the compact 55 mm body keeps the envelope tight. At 0.5 MPa the full push is 402 N, but plan real work around 241 N so the cylinder never labours near its limit. The magnet is built in as standard, so CMSG, DMSG or EMSG switches drop straight on for end-of-stroke sensing, and the CA pivot back cover lets the rod follow a swinging link without extra brackets.

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 MAC32X55SCA Is Used
Die ejector on an indexing table
Ejecting finished brass fittings from a 55 mm die pocket on a rotary indexing press, where 241 N of working force clears the part every cycle.
Gate diverter on a bottling line
Swinging a divider gate between two conveyor lanes on a bottling line; the CA pivot back cover follows the arc without a separate clevis bracket.
Carton flap tucker
Folding top flaps on small shipping cartons at up to 800 mm/s, with the variable cushion absorbing the flap slam at full extension.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SCA the Right Cylinder?
Need less force? The 25 mm bore delivers 245 N at 0.5 MPa; step up to the 40 mm bore for 628 N on the same 1/8" port. Remember a plain MAC freewheels when air is lost - the piston holds nothing on its own, so add a rod lock or pilot check valve if the load must stay put. The CA pivot suits swinging mounts; FA flange, LB foot or SDB pivot brackets cover fixed installations, and I or Y rod knuckles take side-play out of the linkage.
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 MAC32X55SCA FAQ
At 0.5 MPa the 32 mm bore pushes 402 N and pulls 345.6 N; at 0.7 MPa that rises to 563 N push and 483.8 N pull. The theoretical ceiling is 82 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, fluid air filtered to 40 um.
Its barrel is stainless steel and the carbon-steel rod carries a 20 um hard-chrome plating, so splash, humidity and mild washdown chemicals are handled without the flaking paint seen on steel-bodied minis. The aluminium alloy covers are riveted and rolled onto the barrel - no tie-rod bolts to work loose. Operating temperature spans -20 to +70 C.
