Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 225mm 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 MAC25X225SU
Designed for slim machine frames where a bulkier actuator will not fit, this 25 mm bore MAC extends 225 mm and still pushes 245.3 N at 0.5 MPa (343.4 N when supply reaches 0.7 MPa). Running on 0.15-1.0 MPa (22-145 psi), it cycles between 30 and 800 mm/s, and its variable air cushion at each end takes the jar out of fast, full-stroke stops.
The U flat-end back cover on this variant presents a flat, drilled face that bolts flush against a machine wall without brackets - a clean fit for fixed linear slides. Inside, the stainless barrel and 20 um hard-chrome plated rod hold up in damp shop air, with riveted aluminium covers sealing the round body. The magnet is built in as standard, so CMSG, DMSG or EMSG switches flag both end positions, and despite the 50 kgf theoretical rating at 1.0 MPa, plan vertical lifts at about 12 kg with a 2:1 pressure 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 MAC25X225SU Is Used
Test-sled actuator
Pushes a QA sample sled through a 225 mm wear cycle on a life-test rig, with cushioned ends smoothing every reversal.
Chute diverter
Swings a gravity-chute diverter arm at a pick station, the flat U cover bolting directly to the chute frame.
Coating fixture clamp
Clamps a circuit-board jig against a stop during conformal coating, a CMSG switch confirming the full-clamp position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SU the Right Cylinder?
Compare before you commit: a 20 mm bore gives 157 N push at 0.5 MPa for lighter gates, while a 32 mm bore steps up to 402.2 N for heavier tooling. Bear in mind that a double-acting MAC will not hold position if air fails - the rod drifts freely - so pair it with a pilot check valve or rod lock on vertical or load-holding jobs. Add FA flange, LB foot or SDB pivot brackets as the frame requires, and an I or Y knuckle for linkages; over a 225 mm stroke, keep the load guided so the rod sees minimal side force.
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 MAC25X225SU FAQ
At 0.5 MPa the piston delivers 245.3 N forward and 206.1 N back; at 0.7 MPa it is 343.4 N forward and 288.5 N back, with a theoretical maximum of 50 kgf at 1.0 MPa. Supply pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof limit.
The barrel is high-precision stainless steel and the rod is carbon steel hard-chrome plated to 20 um, so condensation, coolant mist and occasional washdown do not chew the surface the way they would a painted mini. Aluminium covers are riveted onto the tube, keeping the round body reliably sealed.
