Airtac MAC Stainless Steel Mini Air Cylinder MAC32X155SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X155SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 155mm 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 MAC32X155SCA
The MAC32X155SCA pairs a 32 mm bore with a 155 mm stroke and a CA pivot back cover, giving a double acting mini cylinder that pushes 402 N and pulls 346 N at 0.5 MPa. A variable air cushion sits at both ends, so end-of-stroke shock can be dialed out with the needle screws and faster or heavier moves stay gentle on the covers.
The riveted body rolls a stainless-steel barrel into aluminium-alloy covers with a hard-chrome plated 12 mm rod, a combination that shrugs off mild corrosion and washdown far better than painted mini cylinders in damp or food areas. Every unit ships with the piston magnet built in as standard, so CMSG, DMSG or EMSG switches clip on without a special-order piston. In round numbers, plan for about 241 N of real work at 0.5 MPa rather than the full 402 N rating, and the bore will lift about 41 kg vertically, or roughly 20 kg when you halve that for 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 MAC32X155SCA Is Used
Carton pusher on a sortation line
The 155 mm stroke sweeps parcels across a lane while 402 N of push at 0.5 MPa supports speeds up to 800 mm/s, with the adjustable cushion softening every stop.
Bench jig lift
With roughly 20 kg of vertical lift capacity on a 2:1 margin, the cylinder raises fixture plates or small castings on an assembly bench under switch-monitored control.
Dial table part eject
Push finished parts off a rotary index plate; the CA pivot eye lets the tooling link swing freely as each part clears its nest.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X155SCA the Right Cylinder?
At 402 N push at 0.5 MPa this bore is the step up when a 25 mm MAC (245 N push) stalls under the load, while a 40 mm MAC (628 N push) suits jobs needing well over double the force. The MAC does not hold its stroke when air is removed or the valve centres, so fit a rod lock or pilot check valve if a mid-stroke load must stay put. The CA pivot eye swings on a pin without extra brackets; add FA flange, LB foot or SDB pivot mounts as the frame demands, and on this 155 mm stroke keep side loads low or guide the rod externally to protect it from bending. Ports are 1/8 inch PT with an M10x1.25 male rod thread; G and NPT options are available at order time.
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 MAC32X155SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push rises to 563.0 N, and the theoretical maximum is 82 kgf at 1.0 MPa. Air supply spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure. Ports are 1/8 inch PT, the rod is 12 mm hard-chrome steel with an M10x1.25 male thread, and speed runs 30-800 mm/s.
No. Every MAC cylinder leaves the factory with the magnet built into the piston, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel for end-of-stroke or mid-stroke signalling. Back the cushion needle screws off before first run and open them gradually to tune the air cushion at each end.
