Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 175mm 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 MAC25X175SCA
The longest of this 25 mm group at 175 mm, the MAC25X175SCA swings long link arms and reaches into deep guards while pushing 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa. It is double acting with a variable air cushion at both ends, and the CA pivot rear cover pins directly to rotating levers or bell cranks.
In service, count on about 147 N of real working force at 0.5 MPa, lifting roughly 12 kg vertically with a 2:1 margin, and keep fast heavy stops within cushion range so the covers never take the hit. The rolling-packed stainless barrel plus hard-chrome plated rod stands up to humid workshops and light washdown; the built-in magnet pairs with CMSG, DMSG or EMSG switches as standard equipment.

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 MAC25X175SCA Is Used
Rotary arm on a small palletiser
The CA pivot eye pins to the turning arm; 245 N of push swings layers of bags onto a pallet with a cushioned park position.
Lane diverter on a carton sorter
175 mm of travel sweeps cartons between lanes; the stainless body tolerates the humid, dust-laden air of a distribution hub.
Slide advance on a tube-bending fixture
Double-acting push and pull advance and retract a bending die slide; DMSG switches on the standard magnet confirm both ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCA the Right Cylinder?
For a bit less muscle, the bore 20 MAC delivers 157 N at 0.5 MPa; for more, the bore 32 delivers 402.2 N. The 25 mm class suits medium clamps and part lifts. On a 175 mm stroke the slenderness ratio matters: carry side loads on linear guides and use an I or Y rod knuckle with the CA pivot to absorb alignment error. U and CM back covers are also available if a fixed or round rear mount fits better.
Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s. Remember the rod moves freely when air is lost, since the cushion is not a brake, so hang suspended loads on a rod lock or pilot check valve instead.
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 MAC25X175SCA FAQ
25 mm bore, 175 mm stroke, push 245.3 N and pull 206.1 N at 0.5 MPa, push 343.4 N at 0.7 MPa, about 50 kgf theoretical at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), 30-800 mm/s, 1/8" ports.
Both ends carry needle-screw air cushions. Back the screws fully out before the first run, then close them gradually until the load decelerates smoothly. This variable cushioning lets you run up to 800 mm/s without hammering the aluminium covers.
