Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 70mm 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 MAC32X70SCA
With a 32 mm bore driving 402 N at 0.5 MPa, the MAC32X70SCA earns its place on pivoting machines that need compact punch. This AirTAC MAC mini cylinder is double acting with a variable air cushion at both ends, so end-of-stroke shock can be dialled out rather than absorbed by the covers.
The CA pivot back cover is rolled onto the stainless barrel together with the aluminium covers, giving a clevis-style pivot without bolt-on brackets. Each cylinder ships with a built-in magnet, so CMSG / DMSG / EMSG switches drop straight on. Pull force is 346 N at 0.5 MPa and the push climbs to 563 N at 0.7 MPa, with 82 kgf theoretical maximum; for real duty count on about 240 N, enough to lift roughly 20 kg vertically on a 2:1 margin.

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 MAC32X70SCA Is Used
Hinge-arm weld clamp
Swinging a weld fixture clamp arm closed on sheet-metal brackets at a fabrication cell, with the pivot cover matching the arm linkage.
Carton flap tucker
Tucking the last flap on a carton sealer head, where the cushion lets the tucker run fast without slamming.
Sorter chute diverter
Kicking small parcels between two gravity chutes in a distribution hub, magnet-driven sensors confirming each throw.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCA the Right Cylinder?
At 70 mm stroke this sits well inside the 500 mm standard range for bore 32. Step down to a 25 mm bore (245 N push at 0.5 MPa) for lighter clamps, or up to 40 mm (628 N) when the frame allows. The CA pivot pairs with an SDB pivot bracket for swing links, or an LB foot when the body must be fixed. Operating window is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s. Note the piston drifts freely once air is removed - the cushion is not a brake, so use a rod lock or pilot check valve where a load must be held.
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 MAC32X70SCA FAQ
Push is 402 N and pull 346 N at 0.5 MPa; at 0.7 MPa push reaches 563 N with 484 N pull, and the theoretical ceiling is 82 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi), air filtered to 40 um, speed 30-800 mm/s.
Both ends carry a variable air cushion with needle screws. Back them fully off before the first cycle, then close them gradually until the 70 mm stroke ends softly. Running too tight from new overheats the cushion and drags the rod speed down.
