Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 225mm 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 MAC25X225SCM
Long-travel duty is where this bore 25 MAC earns its keep: with 225 mm of stroke it carries 245.3 N of push force at 0.5 MPa (206.1 N on retract), so a slide or transfer head can be driven across a wide envelope without giving up a mini-cylinder footprint. Fed with air at 0.15-1.0 MPa (22-145 psi), the rod moves at 30-800 mm/s, and a variable air cushion at both ends absorbs the shock that a 225 mm run can build up.
The stainless round barrel with its hard-chrome plated rod shrugs off washdown and mild corrosion far better than painted mini bodies, while the CM round-end back cover on this variant takes a pivot pin directly - no adapter bracket needed. Every MAC ships with the magnet built in, so CMSG, DMSG or EMSG switches clip straight onto the barrel for end-of-stroke signals. As a sizing rule of thumb, keep real work near 147 N of the rating, or trust the rod to lift about 12 kg vertically with a 2:1 margin.

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 MAC25X225SCM Is Used
Packaging line pusher
Ejects cartons sideways off a 400 mm belt section at a transfer point, the 225 mm stroke reaching across the full lane width.
Gate latch actuator
Drives a sliding machine-guard latch over its full travel, cushioned stops preventing a slam at either end of the run.
Paint-line jig elevator
Reciprocates small jigs vertically on a dip rack, lifting parts up to roughly 12 kg where the stainless barrel shrugs off washdown.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X225SCM the Right Cylinder?
Size down to a 20 mm bore (157 N push at 0.5 MPa) when the load is light and cycle speed matters more than force; step up to a 32 mm bore (402.2 N) when pushing or clamping harder. Rod thread is M10x1.25 and air ports are 1/8". Like every double-acting MAC, this cylinder drifts if supply air is lost - the piston is free to move - so add a rod lock or pilot check valve wherever a load must stay put. FA flange, LB foot or SDB pivot brackets bolt on as the frame needs, and the I and Y rod knuckles pair naturally with the CM round end.
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 MAC25X225SCM 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 push and 288.5 N pull. The theoretical ceiling is 50 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), the rod travels 30-800 mm/s, and ports are 1/8".
No. The magnet comes standard in the piston, so CMSG, DMSG and EMSG switches mount straight onto the stainless barrel without a special-order piston or shimming.
