Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 125mm 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 MAC25X125SCA
The MAC25X125SCA is a 125 mm stroke, bore 25 mini cylinder that is double acting and carries a variable air cushion at both ends, letting you tune away end-of-stroke shock instead of hammering the covers. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; step up to 0.7 MPa and those become 343.4 N push and 288.5 N pull, with 50 kgf available in theory at 1.0 MPa. Size real duty around 147 N of that 0.5 MPa push figure and the cylinder will run comfortably below its rating.
Construction is a riveted round body: a stainless-steel barrel rolled onto aluminium covers with a hard-chrome plated rod, a combination that tolerates washdown and damp corners far better than painted minis. A magnet is built in as standard, so CMSG, DMSG or EMSG switches clamp straight onto the barrel with no special-order piston. The CA pivot back cover takes a swinging linkage directly, the port is 1/8 inch, and operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MAC25X125SCA Is Used
Small-parts staking press
Drives a light staking or marking tool on an electronics assembly bench, where 245 N at 0.5 MPa is ample and the air cushion protects the tool tip at bottom of stroke.
Conveyor gate diverter
Swings a product deflector gate between two lanes on a packaging line, using the CA pivot back cover as the hinge point without extra linkage brackets.
Filling machine lid clamp
Clamps container lids at a food-grade filling station, where the stainless round barrel and hard-chrome rod shrug off daily hose-down.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCA the Right Cylinder?
Compare before you commit: a bore 20 MAC delivers 157.0 N push at 0.5 MPa, while a bore 32 reaches 402.2 N, so the 25 sits squarely in the mid-range for fixtures and small actuators. Note the cushion is not a brake - remove air and the rod drifts freely, so add a pilot check valve or rod lock when the load must stay put. At 125 mm the rod is fairly exposed; guide the load externally if any side force is present. If pivoting does not suit the machine, the same bore is offered with U flat-end or CM round-end covers plus FA flange, LB foot or SDB pivot brackets.
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 MAC25X125SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa, 343.4 N push and 288.5 N pull; theoretical maximum is 50 kgf at 1.0 MPa. It is double acting with a variable air cushion at both ends, runs 30-800 mm/s, and takes 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um.
Back both cushion needle screws fully off before the first strokes, then close them gradually until the load lands at each end without a bang. This keeps the 125 mm stroke smooth across the full 30-800 mm/s speed range and prevents cover damage.
