Airtac MAC Stainless Steel Mini Air Cylinder MAC25X310SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X310SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 310mm 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 MAC25X310SCA
Long travel in a slim round shell: the MAC25X310SCA sweeps 310 mm from a stainless barrel that AirTAC rolls sealed against aluminium-alloy covers and a stainless block. Double acting with a variable air cushion at each end, it produces 245.3 N at 0.5 MPa - roughly 147 N of honest working force, enough to raise about 12 kg against gravity with a 2:1 margin.
The CA pivot back cover accepts a clevis-style pin directly, so linkages swing without bolt-on brackets. Hard-chrome plating (20 um) over the carbon-steel rod protects the long exposed stroke in damp or dusty plants, and the standard piston magnet feeds position signals to CMSG / DMSG / EMSG switches.

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 MAC25X310SCA Is Used
Lid lift on a mixing tank
A clevis pin in the CA cover raises a 10 kg tank lid through 310 mm; the roughly 12 kg vertical capacity leaves margin for gasket drag.
Z-axis part ejector
Pushes finished bushings off an automated lathe fixture into a chute, the cushioned landing preventing bounce-back at stroke end.
Outdoor gate latch
Actuates a sliding latch on a warehouse access gate, the chrome-plated rod standing up to outdoor humidity year round.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X310SCA the Right Cylinder?
For this travel the 25 mm bore sits mid-range: the 20 mm MAC manages 157.0 N at 0.5 MPa, while a 32 mm bore reaches 402.2 N if the load grows. Over 310 mm, guard the rod - align the load on its axis or run external guides, since long exposed strokes magnify bending on the 10 mm rod. With no air the piston sits wherever the load leaves it, so a rod lock or pilot check valve is the answer for held positions. The SDB pivot bracket pairs naturally with the CA cover; FA flange and LB foot suit rigid frames.
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 MAC25X310SCA FAQ
Expect 245.3 N push and 206.1 N pull at 0.5 MPa, rising to 343.4 N push and 288.5 N pull at 0.7 MPa, with a 50 kgf theoretical maximum at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), travel 30-800 mm/s.
Keep external loads guided and on the rod axis, since long strokes magnify side-load bending on the 10 mm rod. The CA pivot back cover takes a clevis pin, and an SDB pivot bracket completes the swinging mount. Open the cushion needle screws before first run, then close them gradually.
