Airtac MAC Stainless Steel Mini Air Cylinder MAC25X465SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X465SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 465mm 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 MAC25X465SCA
With a 465 mm reach from a 25 mm bore, the MAC25X465SCA is a double-acting round-body mini cylinder with a variable air cushion at each end. Push force at 0.5 MPa is 245 N (206 N pulling), rising to 343 N at 0.7 MPa - a useful step up for long-travel pusher arms that still need to fit a compact machine frame. The 10 mm hard-chrome steel rod runs in a stainless barrel riveted to aluminium covers, so mild corrosion and washdown splash do not shorten its service life the way a painted housing would.
The variable air cushions let you bleed end-of-stroke impact down while running 30-800 mm/s, and the factory-fitted piston magnet accepts CMSG, DMSG or EMSG switches with no special-order piston. For practical sizing, allow roughly 147 N of real work at 0.5 MPa - enough to lift about 12 kg vertically with a 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 MAC25X465SCA Is Used
Blister reject gate
Swings a reject flap on a pharma blister line, pivoting on the CA cover pin to clear 465 mm of lane without extra brackets.
Tray swing stopper
Acts as a pivoting stop on a bakery tray conveyor, with the 147 N working margin handling loaded aluminium trays.
Vial lane diverter
Feeds CMSG switches at both cushioned ends to confirm vial-lane diversion on a dairy or beverage filling deck.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X465SCA the Right Cylinder?
Drop to a 20 mm bore (157 N push at 0.5 MPa) for lighter gates; step up to 32 mm (402 N) if 245 N feels marginal. Like any double-acting cylinder without a check valve or rod lock, the rod drifts when supply air fails - add a pilot check valve where a position must be held. The CA pivot back cover swings freely on a pin; FA flange or LB foot brackets suit fixed rigs. At 465 mm of stroke, keep side loads off the rod or fit an external guide, and confirm couplings on the M10x1.25 rod thread stay aligned.
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 MAC25X465SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures are 343.4 N push and 288.5 N pull. The theoretical ceiling is about 50 kgf at 1.0 MPa. The port is 1/8" and the rod thread is M10x1.25.
The stainless tube with a 20 um hard-chrome rod resists washdown splash and mild corrosion, while the two-way piston seal stores grease for longer life - a real edge in damp food or outdoor spots. Operating range is 0.15-1.0 MPa (22-145 psi), -20 to +70 C.
