Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MAC32X25SCM
The MAC32X25SCM pairs AirTAC's riveted mini-cylinder body - a stainless barrel rolled into aluminium covers - with the CM round-end back cover, leaving a compact rounded tail for tight machine frames. This is a double-acting unit with a variable air cushion at both ends, so end-of-stroke impact is adjustable rather than fixed.
Force class matters at this bore: 402 N extend and 346 N retract at 0.5 MPa, climbing to 563 N at 0.7 MPa. That is roughly the muscle to lift a 41 kg load vertically on paper; halve it to about 20 kg for a sensible 2:1 margin. The standard-fit magnet means position feedback with CMSG, DMSG or EMSG switches needs no special-order 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 MAC32X25SCM Is Used
Tray diverter
Swinging a diverter arm on a parcel sorter's infeed conveyor; 402 N at 0.5 MPa moves loaded trays and the CM round end tucks into the sorter frame.
Sample cup sealer
Pressing sample cups onto a sealing plate in a lab autosampler, where the 25 mm stroke matches the cup depth and the cushion prevents cup crush at the stop.
Tooling lock pin
Driving a lock pin into a changeover fixture on a CNC pallet system; a CMSG switch on the standard magnet confirms full insertion.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCM the Right Cylinder?
Compared with the 25 mm bore's 245 N at 0.5 MPa, this 32 mm unit gives close to 65% more push; the 40 mm MAC at 628 N is the next step if a fixture demands it. Note that when the solenoid valve centres or supply air fails, the rod drifts freely - the cushion is not a brake, so specify a rod lock or pilot check valve where a load must stay put. The CM round end suits pivot eyes and compact rear fixings; FA flange, LB foot or SDB pivot mounts cover the body side. Ports are 1/8" on all 32 mm bores, selectable as PT, 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 MAC32X25SCM FAQ
At 0.5 MPa: 402 N push, 346 N pull. At 0.7 MPa: 563 N push, 484 N pull. Maximum theoretical force at 1.0 MPa is 82 kgf. Air supply must be filtered to 40 um and regulated between 0.15-1.0 MPa (22-145 psi); proof pressure is 1.5 MPa (215 psi).
Yes - the MAC32X25SCM has a variable air cushion at both ends. Screw the needles fully open before commissioning, then close them in small steps until the load settles into each end without a bang. Cycle speed can run anywhere from 30 to 800 mm/s once the cushion is dialled in.
