Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 700mm 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 MAC25X700SU
Vertical lifts and clamp beams both land comfortably in the MAC25X700SU's range: a 25 mm double acting bore over a 700 mm made-to-order stroke, with a U flat-end cover that bolts flush against a machine plate. Push is 245 N at 0.5 MPa and 343 N at 0.7 MPa, the rod returns under air at 206 N, and needle-screw cushions at each end temper the stroke ends.
Treat 147 N as the honest working push at 0.5 MPa and the drive stays cool even at 800 mm/s. On lift duty the same 245 N corresponds to roughly 25 kg vertical, about 12 kg once a 2:1 margin is applied - enough for a fixture riser or a weighed sample basket. The stainless barrel with its chrome-plated rod shrugs off cutting-fluid mist, and the built-in magnet feeds CMSG, DMSG or EMSG switches with no special-order piston.

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 MAC25X700SU Is Used
Fixture riser on an automotive weld cell
Lifts a welding fixture plate between cycles; about 12 kg vertical capacity with a 2:1 margin covers the plate plus its clamps.
Clamp beam on a stone-saw cutting table
147 N of usable push at 0.5 MPa clamps slab offcuts without marring them, and the cushion stops the beam snapping onto the table.
Stretch station on a film-wrap carriage
Runs up to 800 mm/s to keep pace with the wrap head, while DMSG switches confirm both ends of the 700 mm pull for the controller.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SU the Right Cylinder?
Choose 20 mm (157 N push at 0.5 MPa) for a lighter riser, or move to 32 mm (402 N push at 0.5 MPa) when the beam also compresses a gasket. The flat-end U cover fixes the cylinder square to a plate, while FA flange or LB foot brackets take bending load off the 700 mm rod if the load hangs off-axis. Because a de-energised MAC rod coasts freely - the cushion is a shock damper, not a brake - fit a rod lock whenever a raised fixture must stay up through an air drop.
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 MAC25X700SU FAQ
The 25 mm bore yields 245 N push and 206 N pull at 0.5 MPa, 343 N push and 289 N pull at 0.7 MPa, and a theoretical peak of 50 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi), and cycle anywhere from 30-800 mm/s. The 700 mm stroke is a non-standard, to-order length; the standard maximum is 500 mm.
A 700 mm rod shows corrosion first, so the hard-chrome plating over carbon steel matters: it resists rust from cutting fluid, washdown and outdoor humidity far better than bare steel. The aluminium covers are riveted onto the stainless tube for a sealed round body, and the fitted magnet keeps CMSG, DMSG or EMSG switching available at any position.
