Airtac MAC Stainless Steel Mini Air Cylinder MAC25X32SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X32SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 32mm 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 MAC25X32SU
A 32 mm throw is all about tight envelopes and fast repeats. Even at this compact stroke the 25 mm bore produces 245.3 N of push and 206.1 N of pull at 0.5 MPa (72 psi), cycling 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air, double acting with cushioning at both ends.
Construction is a stainless round barrel with rolled-on aluminium covers and a 10 mm rod plated in 20 um hard chrome, an easy-to-clean combination for coolant mist and rinse areas. The piston magnet comes fitted, letting CMSG and EMSG sensors sit right where the short stroke ends. In practice, keep your working demand near 147 N at 0.5 MPa, which corresponds to lifting about 12.5 kg vertically before a 2:1 derate.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MAC25X32SU Is Used
Dowel press fixture
Seats dowels into die-cast enclosures using about 147 N of effective push per cycle.
Small-parts diverter
Flips a 32 mm sorter gate between two chutes on a packaging line running up to 800 mm/s.
Sample nest clamp
Clamps vials or PCBs in a QC test nest and releases each cycle, cushioned in both directions.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X32SU the Right Cylinder?
Downsize to a 20 mm bore (157.0 N at 0.5 MPa) for tiny clamps, or step up to 32 mm (402.2 N) for stiffer pressing work. On this short throw, side load is seldom the problem; valve-centred creep is, so remember the rod will move if air is lost and add a check valve or rod lock wherever a position must be kept. The U flat-end cover takes fixed mounting directly, LB feet or an SDB pivot bracket handle the rest, and the standard magnet gives CMSG / DMSG / EMSG detection without any option code.
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 MAC25X32SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa those become 343.4 N and 288.5 N, with a 50 kgf theoretical maximum at 1.0 MPa. Run it on 40 um filtered air at 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s.
Yes. The variable air cushion is adjusted by needle screws at both ends: back them off before the first run, then close them gradually until end-of-stroke knock disappears. This protects the aluminium covers when you push cycle speed toward 800 mm/s.
