Airtac MAC Stainless Steel Mini Air Cylinder MAC25X200SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X200SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MAC25X200SUH
A 200 mm working range from a 25 mm bore puts this MAC in the mid-thrust class: 245.3 N forward and 206.1 N back at 0.5 MPa, delivered by a riveted stainless barrel with a hard-chrome plated rod that shrugs off splash and humidity. Air cushioning is adjustable at both end covers, letting you tame impact on heavier or faster moves without slowing the whole cycle.
Cushion tuning also protects the aluminium covers when the cylinder runs near the top of the 30-800 mm/s band. Vertical lifting math: the 245.3 N push equals about 25 kg of theoretical lift, so keep parts under 12 kg for a comfortable 2:1 reserve. Switch feedback needs no special order - the piston magnet is standard, ready for CMSG, DMSG and EMSG reed switches.

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 MAC25X200SUH Is Used
Label-head lift on a bottling line
The 200 mm stroke raises the applicator clear of passing bottles; 245 N push at 0.5 MPa overcomes head weight plus spring bias with room to spare.
Tote stopper at a pick-module exit
A cushioned 200 mm throw drops the stop blade between totes; the stainless barrel tolerates the washdown routine of a food-grade distribution centre.
Lid clamp on a lab autoclave loader
Chrome-plated rod and stainless tube resist repeated steam-adjacent humidity; 206.1 N pull retracts the clamp the moment the cycle ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X200SUH the Right Cylinder?
Compare against neighbours before committing: the 20 mm bore manages 157 N at 0.5 MPa and the 32 mm bore reaches 402.2 N, so choose the 32 if your working force grows past about 147 N. Remember the piston free-floats when supply drops - a plain MAC will not park a load mid-stroke, so pair it with a check valve where holding matters. The U-type back cover takes a direct flat mount, while FA, LB or SDB brackets cover flange, foot and pivoting frames. One caution: the trailing H in this ordering code does not appear in the published suffix chart, so confirm its exact meaning from the current datasheet before ordering. The 10 mm rod carries an M10x1.25 thread; 1/8" ports feed the cushioned chambers.
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 MAC25X200SUH FAQ
Push at 0.5 MPa is 245.3 N, pull 206.1 N; at 0.7 MPa expect 343.4 N push and 288.5 N pull, with a 50 kgf theoretical maximum at 1.0 MPa. Operating window is 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), fluid air filtered to 40 um, -20 to +70 C.
No - every MAC ships with the piston magnet fitted, so CMSG, DMSG or EMSG switches mount straight onto the barrel for position feedback. The cushioning is a variable air cushion: back the needle screws out on commissioning and close them gradually. Cushions are not a load brake, and the rod will drift if air is lost.
