Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 190mm 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 MAC25X190SU
At a 25 mm bore this AirTAC MAC turns 0.5 MPa shop air into 245.3 N of push and 206.1 N of pull, rising to 343.4 N at 0.7 MPa, with an operating window of 0.15-1.0 MPa (22-145 psi). It is double acting, so air drives the rod out and back over the 190 mm stroke, and a variable air cushion at each end soaks up stop shock at cycle speeds from 30 to 800 mm/s.
Because the round barrel is stainless steel with a hard-chrome plated rod, it survives washdown and humid corners that rust painted mini cylinders, and the aluminium covers are rolled onto the tube rather than bolted through tie rods. Keep to roughly 147 N of dependable continuous force at 0.5 MPa once a service margin is budgeted. The flat-end U back cover mounts rigidly to fixed brackets, and the built-in magnet works with CMSG, DMSG or EMSG switches 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 MAC25X190SU Is Used
Reject gate pusher
Flicks misfilled bottles off a bottling line reject chute at up to 800 mm/s, with the cushion damping each hit against the gate stop.
Tray indexing push
Feeds bakery trays onto a conveyor spur one at a time; 245 N at 0.5 MPa clears a loaded tray without hammering the rack.
Oven damper actuation
Swings the exhaust damper on a powder-coat oven via the flat-end U mount, the magnet proving open and closed to a DMSG switch.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SU the Right Cylinder?
Bore 20 tops out at 157.0 N of push at 0.5 MPa, so step up to this 25 mm when your load needs the extra reach; bore 32 gives 402.2 N when you outgrow it. The piston drifts whenever air is removed or the valve centres, so add a pilot check valve if the rod must stay put. The 190 mm stroke is long for a mini, so keep side loads off the rod or guide them externally. Order FA flange or LB foot brackets as needed, and the standard magnet pairs with CMSG or DMSG switches.
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 MAC25X190SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N and pull to 288.5 N. The theoretical maximum at 1.0 MPa is 50 kgf. Ports are 1/8 inch and the rod thread is M10x1.25.
Back both cushion needle screws fully off before the first cycles, then close them gradually until end-of-stroke impact disappears. This protects the aluminium covers when the 190 mm stroke is run fast or loaded near its 147 N continuous working force.
