Airtac MAC Stainless Steel Mini Air Cylinder MAC25X800SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X800SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 800mm 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 MAC25X800SCA
A made-to-order 800 mm stroke on a 25 mm stainless round barrel, this MAC cylinder runs double acting with a variable air cushion at each end. At 0.5 MPa it pushes 245 N and pulls 206 N; raise the supply to 0.7 MPa and push reaches 343 N. The riveted stainless tube and hard-chrome plated 10 mm rod shrug off damp, washdown and outdoor air that blister painted minis.
The CA pivot back cover swings on a clevis pin with no extra adaptor, and a built-in magnet ships as standard, so CMSG, DMSG or EMSG switches clip straight on. For everyday sizing keep real work near 147 N at 0.5 MPa rather than the full rating - on paper the rod lifts roughly 25 kg vertically, about 12 kg with a comfortable 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 MAC25X800SCA Is Used
Pallet diverter pusher
An 800 mm reach crosses a full 700 mm roller lane; with about 147 N of practical force it shunts loaded pallet totes aside at up to 800 mm/s.
Sliding machine guard
The clevis-pivoted CA mount tracks a sliding sheet-metal guard on a press brake, while the air cushion catches the door at both ends of the long run.
Lift gate on a bottling filler
Raising a 12 kg spray hood is easy margin for this bore; a pilot check valve holds the gate if plant air ever drops.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X800SCA the Right Cylinder?
Below this size the 20 mm bore delivers 157 N at 0.5 MPa; above it, the 32 mm bore gives 402 N. Because 800 mm exceeds the 500 mm standard stroke limit, this length is made to order - and at that reach, guide the rod externally, since side loads bend a 10 mm rod quickly. The MAC holds no position when air is dropped or the valve centres, so add a rod lock or pilot check valve for suspended loads. Combine the CA pivot with an LB foot, FA flange or SDB bracket; ports are two 1/8" and the rod thread is M10x1.25.
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 MAC25X800SCA FAQ
At 0.5 MPa the 25 mm bore pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push is 343.4 N, and the theoretical maximum is 50 kgf at 1.0 MPa. Supply runs 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speeds span 30-800 mm/s, and both ports take 1/8" fittings on a 10 mm rod with M10x1.25 male thread.
The barrel is high-precision stainless steel rolled onto aluminium-alloy covers, and the carbon-steel rod carries a 20 um hard-chrome plate. That combination resists the mild corrosion and repeated washdown that swell or flake painted mini cylinders, which is why the MAC series suits food, outdoor and damp plant work.
