Airtac MAC Stainless Steel Mini Air Cylinder MAC25X475SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X475SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 475mm 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 MAC25X475SCA
Long travel does not have to mean a bulky actuator: the MAC25X475SCA squeezes 475 mm of cushioned, double-acting travel into a 25 mm round body. It pushes 245 N and pulls 206 N at 0.5 MPa, climbing to 343 N forward at 0.7 MPa - roughly the class needed to lift about 12 kg of real part weight vertically with a 2:1 margin, or shift it horizontally with room to spare.
Every unit ships with the piston magnet already fitted, so CMSG, DMSG or EMSG switches simply drop onto the barrel for end-of-stroke feedback. Air cushions at both ends are needle-adjusted on commissioning: back them off first, then close gradually to suit the 30-800 mm/s speed range.

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 MAC25X475SCA Is Used
Cheese-mould lid lift
Raises hinged lids on a cheese rinsing line, where the wet-environment stainless body outlasts painted minis.
Coffee chute tilt
Tilts a dosing chute on a coffee packer via the CA pivot pin, cushioned ends so the chute never slams.
Poultry guide arm
Positions a guide arm along a portioning conveyor, magnet switches confirming each 475 mm cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X475SCA the Right Cylinder?
For comparison, a 20 mm bore manages 157 N push at 0.5 MPa while a 32 mm bore delivers 402 N - the 25 mm sits mid-class and suits 475 mm gates, chutes and lifters in the 100-150 N working band. Power it from a 1/8" port at 0.15-1.0 MPa (22-145 psi). If the load must stay put when air is lost, remember this cylinder will drift; specify a rod lock or pilot check valve separately. The CA pivot back cover suits swing links, while FA, LB or SDB brackets handle fixed 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 MAC25X475SCA FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N push and 288.5 N pull, with about 50 kgf theoretical maximum at 1.0 MPa. Air supply spans 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
Yes - the magnet is standard on every MAC piston, so CMSG, DMSG and EMSG sensors mount straight onto the stainless barrel with no special-order piston or rework. At 475 mm of travel, switches at both cushioned ends confirm full extend and retract.
