Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 25mm 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 MAC25X25SUH
Damp and dirty surroundings are where the MAC25X25SUH earns its keep: a stainless barrel rolled into aluminium covers, plus a hard-chrome plated rod, holds up against splash and condensation far better than painted or plain-aluminium minis. Bore 25 mm, stroke 25 mm, double acting with adjustable air cushions at each end that tame stop shock across the 30-800 mm/s speed range.
Output is 245.3 N extending and 206.1 N retracting at 0.5 MPa - on a 2:1 margin that lifts about 12 kg of dead weight vertically. The built-in piston magnet is part of the standard build, letting CMSG, DMSG or EMSG switches read end positions straight off the barrel. Because the trailing H on the suffix sits outside the standard CA / U / CM list, confirm the exact back-cover configuration from the datasheet before finalising the order.

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 MAC25X25SUH Is Used
Gate latch on a tote conveyor
Locks gate arms across the lane between totes; 245.3 N at 0.5 MPa gives a firm latch even against hinge friction.
Guide pin lift in a machining cell
Raises locating pins clear of the fixture during part swap; 206.1 N of retract force at 0.5 MPa pulls the pins home reliably.
Hold-down on a CNC router table
Presses sheet stock against the spoilboard for light cuts; the stainless build tolerates coolant mist drifting around the spindle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SUH the Right Cylinder?
Same 25 mm performance window as its siblings: 343.4 N of push at 0.7 MPa when the supply runs high, or drop to a 20 mm bore (157.0 N) or step up to a 32 mm bore (402.2 N) at 0.5 MPa to match the load. When the load must stay put, remember this cylinder wanders once air is removed - trap it with a pilot check valve or specify a rod-lock option.
Verify the SUH suffix detail on the AirTAC datasheet, then match FA flange, LB foot or SDB pivot mounting to the frame. The rod is 10 mm with an M10x1.25 male thread and 1/8" ports.
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 MAC25X25SUH FAQ
Use 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa, against a 50.0 kgf theoretical maximum at 1.0 MPa. The bore is 25 mm with a 10 mm rod, M10x1.25 thread and 1/8" ports.
It is a tail suffix outside the standard MA back-cover list (CA pivot, U flat-end, CM round-end), so confirm the exact configuration from the AirTAC datasheet before ordering. What is certain either way: magnet standard, double acting, variable cushion both ends, 0.15-1.0 MPa (22-145 psi).
