Airtac MAC Stainless Steel Mini Air Cylinder MAC32X312SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X312SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 312mm 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 MAC32X312SCA
A 312 mm stroke on a 32 mm bore gives the MAC32X312SCA long reach backed by 402 N of push and 346 N of pull at 0.5 MPa (563 N at 0.7 MPa). Double acting with a variable air cushion at both ends, it accepts 0.15-1.0 MPa (22-145 psi) and cycles anywhere from 30 to 800 mm/s.
The riveted stainless barrel keeps a body this long straight and rust-free in humid plants where painted tubes scale and leak. For realistic sizing count on about 241 N of dependable push at 0.5 MPa rather than the headline figure - and the cushion dials out arrival shock at both stroke ends. The CA pivot back cover swings freely in linkage arms, and the factory magnet reads through CMSG, DMSG or EMSG switches with no special piston.

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 MAC32X312SCA Is Used
Conveyor indexing lifters
Raises product 312 mm between conveyor levels, with 402 N of push in reserve and cushioned landings at both extremes.
Textile linkage actuation
The CA pivot pin drives loom and knitting-frame lever arms that need free swinging motion over a long stroke.
Hopper slide gates
Slides wide discharge gates open and closed at up to 800 mm/s while the dual cushion tames the slam at each limit.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X312SCA the Right Cylinder?
Weigh the 25 mm bore at 245 N and the 40 mm bore at 628 N (both at 0.5 MPa) before committing to 32 mm. With 312 mm of unsupported travel, keep side loads off the 12 mm rod and guide the load externally - long strokes bend thin rods quickly. Vented air means a drifting rod, so specify a pilot check valve or rod lock wherever the position must persist. SDB pivot and LB foot brackets, combined with the CA cover, cover most frame layouts.
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 MAC32X312SCA FAQ
0.5 MPa: 402 N push, 346 N pull. 0.7 MPa: 563 N push, 484 N pull. Theoretical ceiling 82 kgf at 1.0 MPa. Operating window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, 1/8" port, M10x1.25 male rod thread, 12 mm hard-chrome rod.
A long tube exposes a lot of surface to plant air and washdown mist. Stainless shrugs off the rust that flakes painted barrels and scores seals, while the hard-chrome 12 mm rod adds the same defence at the gland - together they keep the cylinder sealing cleanly over years of humid or outdoor service.
