Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 230mm 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 MAC25X230SU
A 230 mm stroke on a 25 mm bore gives the MAC25X230SU a long, slim reach: 245.3 N of push and 206.1 N of pull at 0.5 MPa (about 25 kgf of column force), rising to 343.4 N at 0.7 MPa. The cylinder is double acting with a variable air cushion at both ends, so end-of-stroke shock stays under control even at the top of the 30-800 mm/s speed range.
AirTAC rolls the aluminium-alloy covers and a stainless-steel block onto the high-precision barrel, and the hard-chrome plated rod (20 um) shrugs off washdown and damp plant air - a real edge over painted minis in food and outdoor stations. Every unit carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip on without a special piston. Working at 0.5 MPa, plan on roughly 147 N of usable push rather than the full 245 N rating.

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 MAC25X230SU Is Used
Tray push-off
Kicks filled trays sideways off a 300 mm wide conveyor at a packaging line transfer point, using the 230 mm stroke to clear the full lane.
Guard-door latch
Drives a sliding latch bolt on a machine guard door; the variable air cushion at both ends stops the latch slamming into its stops.
Sample elevator
Raises a small sample rack of about 12 kg in a lab automation stack, where the stainless barrel tolerates routine wipe-down.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SU the Right Cylinder?
For light pusher duty up to about 150 N, the 20 mm bore (157 N push at 0.5 MPa) is the cheaper pick; if your load needs more than 245 N, step up to the 32 mm bore at 402.2 N. Like any double-acting cylinder, the MAC25X230SU drifts when air is lost or the valve centres - add a pilot check valve or rod lock if the load must stay put. The U flat-end back cover bolts straight to a fixed plate, and the standard magnet suits CMSG / DMSG / EMSG switching along the full 230 mm travel. At this stroke, keep side load on the rod low or fit a guide.
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 MAC25X230SU 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. Theoretical maximum at 1.0 MPa is 50 kgf. Ports are 1/8", the rod is 10 mm with M10x1.25 male thread, and pressure range is 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi).
No - the U flat-end back cover presents a plain mounting face that bolts directly to a plate or bracket. If the application pivots instead, order the CA pivot version (MAC25X230SCA) or add an SDB pivot bracket. The built-in magnet is standard, so CMSG, DMSG or EMSG reed sensors fit without options.
