Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 180mm 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 MAC32X180SCM
A round-end CM back cover gives this model a compact, snag-free rear for enclosed frames, and the MAC32X180SCM behind it behaves like any MAC: a double-acting 32 mm bore with variable air cushioning at both ends, running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um. Rated push is 402 N at 0.5 MPa, rising to 563 N at 0.7 MPa, with 346 N of pull at the lower pressure.
Nothing here is a bolted tie-rod stack - the aluminium covers are rolled onto the stainless tube and sealed, while the 12 mm rod carries 20 um of hard chrome against corrosion and scoring. Because 402 N is theoretical, plan real work at about 240 N and expect near 20 kg of vertical lift with a 2:1 margin. Both cushion needles adjust by hand to soften each stop over the 180 mm stroke, and the fitted piston magnet lets CMSG, DMSG and EMSG switches signal stroke ends straight away.

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 MAC32X180SCM Is Used
Die ejector under a small press
Ejects formed bushings from the die after each stroke; the cushion eases the ejection stop so thin flanges leave without cracking.
Reject kicker at a checkweigher
Pushes underweight packs off the outfeed belt into a reject bin; 402 N at 0.5 MPa clears the pack even with a fast 800 mm/s approach.
Bench shear hold-down
Clamps sheet offcuts ahead of the blade on a light bench shear; the round-end CM rear sits flush inside the machine guard.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SCM the Right Cylinder?
This 32 mm tube covers the mid-band between the 25 mm bore (245 N push at 0.5 MPa) and the 40 mm bore (628 N); below about 200 N of real duty the smaller bore costs less to run. There is no internal lock in a MAC - with the valve centred or the supply off, an unbalanced load will walk the rod - so pair the 180 mm stroke with a pilot check valve or rod lock where holding matters. The 12 mm rod on an 180 mm stroke is happiest pushing in a straight line; add external guides for anything off-axis. The CM round end suits clevis-style rear fixings and enclosed frames, with FA flange, LB foot and SDB pivot options covering the rest; order thread as PT (blank), G or NPT.
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 MAC32X180SCM FAQ
402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, peaking at a theoretical 82 kgf at 1.0 MPa. The bore 32 port is 1/8", the rod 12 mm with an M10x1.25 male thread, and PT (blank), G or NPT threads are available. Working range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C.
Yes. Both cushion needle screws ship open; run the cylinder gently, then close each needle gradually until end-of-stroke knock disappears. Set cushions let you use the top of the 30-800 mm/s range or stop heavier loads without hammering the covers - but a cushion is a shock absorber, never a lock on the rod.
