Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 500mm 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 MAC25X500SCA
Spanning the full 500 mm standard stroke for this bore, the MAC25X500SCA is a riveted round-body mini cylinder with double-acting power and a variable air cushion at each end. Push effort is 245 N at 0.5 MPa and 343 N at 0.7 MPa - enough to keep a long-slide pusher running with about 147 N of true working force once a sensible margin is applied.
The 10 mm hard-chrome rod slides in a stainless tube that shrugs off washdown and outdoor humidity, while rolled aluminium covers keep the assembly light and leak-tight. Needle screws at both ends trim the 30-800 mm/s speed cycle so fast or heavily loaded strokes do not hammer the covers; start with them fully open.

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 MAC25X500SCA Is Used
Box-turn ejector
Pushes corrugated cartons through a 90 degree turning station on a packaging conveyor, cushioned ends protecting the stop face.
Carton lane sorter
Diverts cartons between two sortation lanes, the CA pivot pin allowing a hinged gate action.
Autoclave loader slide
Slides sample racks into a laboratory autoclave, where steam splash favours the stainless barrel and chrome rod.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCA the Right Cylinder?
A 20 mm bore stops at 157 N push at 0.5 MPa and a 32 mm bore reaches 402 N, so the 25 mm splits the difference for 500 mm slides. Where the rod carries nothing but axial load, this stroke works as-is; for anything overhanging, add a guide or use the I or Y rod knuckle to decouple side load. Air supply comes through a 1/8" port at 0.15-1.0 MPa (22-145 psi). Unlike a locked actuator, the rod moves freely once pressure drops - fit a pilot check or rod lock if a held position matters.
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 MAC25X500SCA FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N push and 288.5 N pull, with about 50 kgf theoretical at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi); the proof rating is 1.5 MPa (215 psi).
Both ends carry variable cushions: on first run, screw the needle valves fully open, then close them gradually until end-of-stroke shock disappears at your chosen speed within 30-800 mm/s. This protects the covers without acting as a brake - the piston still drifts when air is removed.
