Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 350mm 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 MAC25X350SCA
A swing point comes built into this cylinder: the CA back cover carries a pivot ear, so the MAC25X350SCA can be clevis-mounted to a moving linkage without shop-made brackets. Inside sits AirTAC's MA construction - a stainless-steel round barrel rolled together with aluminium covers and a hard-chrome plated 10 mm rod. It is double acting, moves at 30-800 mm/s, and breathes through 1/8-inch ports. Operating range is 0.15-1.0 MPa (22-145 psi).
The 25 mm bore turns 0.5 MPa into 245.3 N of push and 206.1 N of pull, rising to 343.4 N at 0.7 MPa with 50 kgf available in theory at 1.0 MPa. Plan your work around 147 N instead of the full rating and the cylinder runs cool and lasts longer. On a vertical lift that is roughly 25 kg, or about 12 kg once you insist on a 2:1 margin. A magnet is fitted as standard, so CMSG, DMSG and EMSG switches mount straight onto the barrel.

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 MAC25X350SCA Is Used
Drilling jig clamp
The rear pivot swings a clamp arm down onto a housing before the drill cycle starts, with 147 N of usable clamp force at 0.5 MPa.
Sorter divert gate
Mounted through its CA ear, the cylinder swings a deflector across a parcel sorter belt in under half a second at full speed.
Carton infeed pusher
Pushes sleeves of cartons square to the sealing head, sized with the 206.1 N pull stroke in mind as well as the push.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SCA the Right Cylinder?
Compared with its neighbours, this bore pushes 245.3 N at 0.5 MPa where the 20 mm MA manages 157 N and the 32 mm reaches 402.2 N - size up if your load sits near 200 N. The pivot ear pairs naturally with an SDB pivot bracket or an LB foot, and I or Y rod knuckles complete a swinging joint. Note the piston drifts the moment air is cut, so a rod lock or pilot check valve is needed for any held position. Over a 350 mm stroke, guide the load on its own bearings and keep side thrust off the rod to avoid bending. Air ports are 1/8-inch; the rod thread is M10x1.25.
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 MAC25X350SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa those rise to 343.4 N and 288.5 N. The theoretical maximum is 50 kgf at 1.0 MPa. It is double acting with a variable air cushion at both ends, runs on 0.15-1.0 MPa (22-145 psi), and cycles anywhere from 30 to 800 mm/s.
The pivot ear is formed into the rear cover itself, so a clevis-type swing joint needs no separate bracket. Add an SDB pivot bracket or LB foot if the frame demands it, and because the magnet is built in as standard, a CMSG or DMSG switch can report end positions without any special-order piston.
