Airtac MAC Stainless Steel Mini Air Cylinder MAC32X315SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X315SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 315mm 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 MAC32X315SCA
The MAC32X315SCA pairs 315 mm of travel with 32 mm bore punch: 402 N extend and 346 N retract at 0.5 MPa, and 563 N extend at 0.7 MPa. It is a double-acting round-body mini whose variable air cushion trims shock at each end of the long stroke, running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi).
Thinking in vertical lift, 402 N at 0.5 MPa works out to about 41 kg theoretical, so with a 2:1 margin this bore raises roughly 20 kg parts with confidence. The stainless barrel and 20 um hard-chrome plating on the rod stand up to mild corrosion and washdown mist, an advantage over painted minis in food and outdoor cells. Its CA pivot cover plus the built-in magnet (CMSG, DMSG, EMSG ready) drop into pivoting frames without adapters.

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 MAC32X315SCA Is Used
Mixer lid raising
Lifts about 20 kg stainless mixer lids through 315 mm of travel, sized with a 2:1 margin on the 402 N push.
Sorter diverter gates
Deflects cartons between sorter lanes using 346 N of return force through the CA pivot pin.
Case erector flap arms
Drives flap-folding arms on case erectors, with the twin air cushion trimming impact across the full 315 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X315SCA the Right Cylinder?
Below it, the 25 mm MAC carries 245 N at 0.5 MPa; above it, the 50 mm unit brings 981 N and 1/4" ports. A plain MAC slides when air is cut - for clamps that must grip through a power loss, add a rod lock or pilot check valve. Mount the 315 mm body on FA flange or LB foot brackets, let the CA pivot cover take the moving pin, and guide the load externally so the rod sees straight thrust only.
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 MAC32X315SCA FAQ
Push 402 N and pull 346 N at 0.5 MPa; push 563 N and pull 484 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, 1/8" air port, M10x1.25 male rod thread on the 12 mm rod.
No. As a plain double-acting cylinder the piston drifts whenever supply drops or the valve centres, and the variable air cushion only softens arrival - it is never a brake. Fit a rod lock or a pilot check valve in the port lines to park a load reliably along the 315 mm stroke.
