Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCA 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 MAC25X300SCA
For pivoting link arms over a long reach, the MAC25X300SCA pairs a 300 mm stroke with a CA back cover whose rear pivot eye swings with the mechanism, so no extra bracket is needed. Behind it sits a 25 mm stainless round barrel rated 245.3 N push and 206.1 N pull at 0.5 MPa, double acting with a variable air cushion you tune at each end cover.
The riveted barrel-and-cover build keeps the seals true over 300 mm of travel, and the hard-chrome 10 mm rod resists corrosion in damp or washed-down cells. Size the job around 147 N of usable push at 0.5 MPa, or think of the bore as lifting about 25 kg vertically - roughly 12 kg once you halve it for margin. Speeds span 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, and the standard magnet accepts CMSG, DMSG or EMSG switches anywhere along the tube.

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 MAC25X300SCA Is Used
Parcel sorter gate flap
Swings a diverting flap on a parcel sorter through its arc; the CA pivot back cover follows the linkage while the cushion sets the flap down gently.
Battery-change tilt link
Tilts a forklift battery stand for extraction; 206.1 N of pull at 0.5 MPa draws the link home and the cushion eases the seat.
Treatment plant sluice gate
Lifts a small water-treatment sluice gate through 300 mm; the stainless barrel and chrome rod stand up to the humid, splashy surroundings.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SCA the Right Cylinder?
The 20 mm bore gives 157.0 N and the 32 mm gives 402.2 N at 0.5 MPa, so choose this 25 mm when the link-arm load falls between them. A 300 mm rod is long for its 10 mm diameter: guide the load, avoid side thrust, and consider intermediate support on fast cycles. When air is lost the rod drifts freely - a pilot check valve or rod lock is the way to hold position. The CA pivot cover handles swinging mounts; FA flange, LB foot or SDB brackets suit fixed frames, and G or NPT ports are order options beside the standard PT.
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 MAC25X300SCA FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa it reaches 343.4 N push and 288.5 N pull, with a 50.0 kgf theoretical maximum at 1.0 MPa. The cylinder is double acting with a variable air cushion at both ends, ported "1/8" with PT thread (G and NPT to order), running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air.
Use the CA pivot back cover where the load swings; switch to FA flange, LB foot or SDB brackets for fixed frames, and keep the 10 mm rod free of side load over the long stroke. The magnet is built in as standard, so CMSG, DMSG or EMSG switches read position at any point along the stainless barrel.
