Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCAFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCAFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 300mm 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 MAC25X300SCAFA
Bolt it flat and swing the load: the MAC25X300SCAFA adds an FA flange to the 25 mm cushioned mini, so the 300 mm-stroke barrel anchors rigidly to a machine face while the CA pivot eye at the back follows a linkage. At 0.5 MPa the double-acting piston delivers 245.3 N on extend and 206.1 N on retract, with a variable air cushion at each end softening 30-800 mm/s cycles.
The body is a rolled stainless-steel tube with a hard-chrome plated 10 mm rod - a combination that shrugs off washdown better than painted minis, which counts in bottling and food plants. Keep design loads near 147 N at 0.5 MPa, or budget the bore as a 25 kg vertical-lift figure, about 12 kg with a 2:1 margin. Supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and the standard magnet lets CMSG, DMSG or EMSG switches clip on for stroke-end feedback.

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 MAC25X300SCAFA Is Used
Bottling line lane divider
Throws a lane divider across a bottle conveyor; the FA flange holds the 300 mm barrel square to the frame while the cushion stops the gate without rattle.
Mixer kettle lid lift
Raises a counterbalanced mixer lid through 300 mm; 245 N of push at 0.5 MPa handles the weight with room to spare.
Case taping hold-down
Presses flap folders square during case sealing; the practical 147 N of push at 0.5 MPa seats each box without crushing the board.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCAFA the Right Cylinder?
This flanged version suits frames where a pivot bracket alone is awkward - the FA face carries the mounting moment while the CA eye still serves a swinging linkage. For lighter jobs the 20 mm bore pushes 157.0 N at 0.5 MPa; for heavier ones the 32 mm reaches 402.2 N. A 300 mm stroke on a 10 mm rod needs aligned, side-load-free guiding, and because the piston is not held when air drops, fit a rod lock or check valve on holding duties. PT ports come standard, with G and NPT as ordering options.
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 MAC25X300SCAFA FAQ
At 0.5 MPa the 25 mm piston gives 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull. Theoretical maximum is 50.0 kgf at 1.0 MPa. It is double acting with a variable air cushion at both ends, running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air through "1/8" PT ports (G or NPT to order).
The FA flange bolts the barrel to a machine face for rigid, aligned mounting over the 300 mm stroke, while the CA pivot back cover still serves a swinging linkage. The stainless-steel barrel, hard-chrome rod, standard built-in magnet for CMSG, DMSG or EMSG switches and the 0.15-1.0 MPa (22-145 psi) rating all carry over from the base MAC.
