Airtac MAC Stainless Steel Mini Air Cylinder MAC25X160SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X160SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MAC25X160SU
Bore 25 with 160 mm of travel is the workhorse slot in the MAC range: 245.3 N of push and 206.1 N of pull at 0.5 MPa, rising to 343.4 N at 0.7 MPa and 50 kgf theoretical at full pressure. Double acting with a variable air cushion at both ends, it soaks up end-of-stroke shock on faster cycles.
The round stainless barrel is riveted to aluminium covers around a hard-chrome plated rod - an edge over painted minis in damp food plants or outdoor gear. Plan on roughly 147 N of useful push at 0.5 MPa, or about 12 kg lifted vertically with a 2:1 margin. The standard-built magnet takes a CMSG, DMSG or EMSG switch straight off the shelf.

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 MAC25X160SU Is Used
Light press fit
Seating small bearings into housings on an assembly press where about 147 N of controlled force is enough.
Case kicker
Tipping cartons off a belt at up to 800 mm/s, with the air cushion sparing the end stops.
Gripper slide
Extend and retract motion on a pick-station slide, a CMSG switch confirming each end of travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X160SU the Right Cylinder?
One bore down, a 16 mm MAC pushes 100.5 N; one up, a 32 mm barrel delivers 402.2 N - match the 147 N-class job to the right frame. Position is not held when air drops: the piston drifts, so fit a rod lock or pilot check for suspended loads. The U flat-end back cover suits fixed bolting, while FA flange, LB foot and SDB pivot brackets adapt the same body.
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 MAC25X160SU FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; theoretical maximum 50 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), port 1/8", rod thread M10x1.25, rod 10 mm.
Both ends carry a variable air cushion - back the needle screws off at first start-up, then close them gradually until the 160 mm stroke lands quietly. Choose U flat-end, CA pivot or CM round-end back covers, plus FA / LB / SDB brackets, to cover most mounts.
