Airtac MAC Stainless Steel Mini Air Cylinder MAC25X210SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X210SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 210mm 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 MAC25X210SU
A 25 mm bore, a 210 mm stroke and a flat-end U back cover define the MAC25X210SU, a cushioned double-acting mini cylinder from AirTAC. Expect 245 N push and 206 N pull at 0.5 MPa, climbing to 343 N at 0.7 MPa; the theoretical peak is 50 kgf at 1.0 MPa.
The stainless barrel resists washdown better than painted bodies, and the hard-chrome plated 10 mm rod keeps seal wear low over long travels. The standard magnet works with CMSG / DMSG / EMSG reed switches. For lifting duty, 245 N equals about 25 kg theoretical, so with a 2:1 margin size vertical loads near 12 kg.

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 MAC25X210SU Is Used
Label press head
Pressing labels or gaskets onto pump housings on a small bench press; 245 N at 0.5 MPa seats adhesive parts cleanly.
Guard door actuator
Opening a sliding machine-guard door across 210 mm; the flat-end U cover bolts flush to the guard frame.
Shelving latch driver
Driving the locking latch on mobile warehouse shelving, with an EMSG switch confirming full extension.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X210SU the Right Cylinder?
Compare against the 20 mm bore (157 N push at 0.5 MPa) for small forces or the 32 mm bore (402 N) for heavier parts. The flat-end U cover mounts flush to a plate, with SDB pivot or LB foot brackets as alternatives, and the built-in magnet means CMSG / DMSG / EMSG switches need no special order. Without air the rod sits wherever load and friction leave it - add a pilot check valve for position holding. Across 210 mm of stroke, keep thrust in line with the bore axis; bending the 10 mm chrome rod shortens seal life fast.
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 MAC25X210SU FAQ
Push 245 N and pull 206 N at 0.5 MPa; push 343 N and pull 288 N at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. Proof pressure 1.5 MPa (215 psi), working range 0.15-1.0 MPa (22-145 psi), temperature -20 to +70 C, speed 30-800 mm/s, 10 mm rod, 1/8" ports.
No. The cushioning is air, not a lock - when pressure drops or the valve centres, the rod drifts. Fit a rod lock or pilot check valve where a hanging or held load matters. For stopping shock, use the variable cushions: start with the needle screws open and close them gradually until the 210 mm travel lands cleanly.
