Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 65mm 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 MAC25X65SCM
A 25 mm bore generating 245 N of push at 0.5 MPa (343 N at 0.7 MPa) makes the MAC25X65SCM a mid-strength actuator for compact round-body duty. It is double acting with a variable air cushion on extend and retract, letting you slow the stroke into a soft landing at both covers.
The CM round-end back cover gives a fixed nose-face mount, and the stainless barrel with hard-chrome carbon-steel rod tolerates splash and outdoor dust better than painted minis. Every unit ships with the piston magnet already fitted, so CMSG, DMSG or EMSG reed switches drop straight on. In vertical use the 245 N push theoretically lifts about 25 kg; halving that for margin means a 12 kg part is a comfortable lift at 0.5 MPa.

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 MAC25X65SCM Is Used
Box forming on carton sealers
Pushes flap-folders home on a case erector; the two-way air cushion stops the 65 mm stroke gently at high cycle rates.
Gate and hatch actuation
Round-end CM mount bolts flush to a frame to swing hoppers or access hatches on grain and feed handling equipment.
Sample press in lab automation
A 12 kg vertical lift with margin suits pressing lids onto sample trays in bottle-filling or analytical lab cells.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X65SCM the Right Cylinder?
Compare a MAC20 bore (157 N push at 0.5 MPa) if the load is light, or a MAC32 (402 N) for presses and heavier clamps. With the CM round end, add an FA flange or LB foot when the body itself must be bolted down. Note the piston drifts the moment air is cut or the valve centres - a cushion is not a lock - so use a rod lock or pilot check valve to hold a position. The 65 mm stroke is a standard length for this bore series.
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 MAC25X65SCM FAQ
Push at 0.5 MPa is 245.3 N and pull 206.1 N; at 0.7 MPa the cylinder delivers 343.4 N push and 288.5 N pull. Maximum theoretical force is 50.0 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
Both ends carry a needle-adjustable air cushion. Back the cushion screws fully off before the first stroke, then close them gradually until end-of-stroke impact disappears. The riveted round body has no external bolts to retighten, unlike a tie-rod style build.
