Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 500mm 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 MAC25X500SU
A 500 mm reach on a 25 mm bore: the MAC25X500SU double-acting mini cylinder pairs that long travel with a riveted stainless-steel barrel and a 20 um hard-chrome plated carbon-steel rod that tolerate washdown and outdoor damp far better than painted alternatives. Air works both ways - extend and retract - and variable air cushions at each end let you tame end-of-stroke impact so faster speeds become practical. At 0.5 MPa expect 245.3 N out and 206.1 N back; at 0.7 MPa the push reaches 343.4 N.
For sizing, treat roughly 147 N as the honest working force at 0.5 MPa. Turned vertical, 245.3 N balances a 25 kg load, so with a 2:1 safety margin the cylinder lifts about 12 kg. The U flat-end back cover suits simple fixed mounting, and every unit carries a standard magnet, so CMSG, DMSG or EMSG switches bolt on without ordering a special 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 MAC25X500SU Is Used
Heat tunnel tray pusher
Feeds shrink-wrapped trays into a heat tunnel over the full 500 mm stroke; the cushion eases each tray to a stop at the tunnel mouth.
Belt tensioner station
Around 147 N of dependable working force at 0.5 MPa tensions a light conveyor belt, with the magnet flagging when tension reaches setpoint.
Pallet-flow lane stopper
Stops totes travelling down a pallet-flow lane; the U flat-end cover fixes straight to the lane frame without adapter plates.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SU the Right Cylinder?
Compare before committing: a bore 20 pushes only 157 N at 0.5 MPa while a bore 32 gives 402.2 N, so the 25 mm class sits mid-range for this stroke. Over 500 mm of travel any side load multiplies at the rod tip - guide the load externally and keep thrust in line. The magnet is factory-fitted; expect the rod to drift freely once supply air is removed, so a pilot check valve or rod lock is the answer where a parked load must stay put.
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 MAC25X500SU FAQ
Design data at a glance: push 245.3 N and pull 206.1 N at 0.5 MPa, push 343.4 N at 0.7 MPa, and a 50 kgf theoretical maximum at 1.0 MPa. The pressure window is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure; ports are 1/8" and the rod thread is M10x1.25.
The rolled stainless-steel barrel plus the 20 um hard-chrome plated rod resist rust in wet, dusty or outdoor conditions where painted-steel minis corrode. That also keeps the bore clean for the seals, which shows up as longer service between overhauls.
