Airtac MAC Stainless Steel Mini Air Cylinder MAC25X320SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X320SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 320mm 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 MAC25X320SU
Pushing 320 mm of travel at a 25 mm bore means 245.3 N of extend force and 206.1 N of retract force at 0.5 MPa (72 psi), with a 30-800 mm/s speed band on 0.15-1.0 MPa (22-145 psi) filtered air. The MAC is double acting, and a variable air cushion at each end absorbs the arrival shock so faster cycles do not hammer the covers.
The body is a riveted stainless barrel with covers rolled on, so there are no tie rods to work loose, and the 10 mm carbon-steel rod carries a 20 um hard-chrome skin that tolerates washdown and humid air. A magnet is built in as standard, so CMSG, DMSG or EMSG switches read position straight off the barrel. Budget about 147 N of usable force at 0.5 MPa, enough to lift roughly 12 kg vertically with a 2:1 margin.

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 MAC25X320SU Is Used
Case transfer pusher
Moves cartons a full 320 mm onto an off-loading conveyor, with the rear cushion taming arrival at speed.
Light staking station
Delivers about 147 N of working force to seat clips and inserts in plastic housings on an assembly bench.
Slide lift on a fixture
Raises a 12 kg nest or gate vertically with margin, then retracts it under air on the return stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X320SU the Right Cylinder?
Size down to a 20 mm bore (157.0 N push at 0.5 MPa) for lighter pusher duty, or up to a 32 mm bore (402.2 N) when the load grows. At 320 mm of exposed rod, keep side loads off the piston: guide the load externally or pick an I or Y knuckle. The flat-end U back cover suits fixed bracket mounting, and an LB foot or FA flange covers frame attachment; the 1/8 inch PT port keeps plumbing compact. If the load must stay parked when air drops, fit a pilot check valve or rod lock, because the bare cylinder will drift.
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 MAC25X320SU FAQ
At 0.5 MPa: 245.3 N push and 206.1 N pull. At 0.7 MPa: 343.4 N push and 288.5 N pull. The theoretical maximum at 1.0 MPa is 50 kgf. Air supply is 0.15-1.0 MPa (22-145 psi), 40 um filtered, with rod speeds of 30-800 mm/s.
The flat-end U cover bolts directly to fixed plates and brackets without extra adapters, and because the piston magnet is fitted as standard, CMSG, DMSG and EMSG switches snap onto the stainless barrel for end-of-stroke signalling with no special piston order.
