Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 25mm stroke, 1/4" 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 MAC63X25SU
Need 1558 N of push but only 25 mm of travel? The MAC63X25SU pairs AirTAC's largest MA bore with a U flat-end back cover that bolts straight against a machine face. It is double acting with a variable air cushion at both ends, so even fast 800 mm/s moves land soft on the covers.
Construction is the classic MA pack: a stainless round barrel, a hard-chrome plated 16 mm steel rod, and aluminium covers rolled onto the tube for a sealed, riveted body. Air at 0.15-1.0 MPa (22-145 psi), filtered to 40 um, does the work, and the built-in magnet feeds CMSG, DMSG or EMSG switches with no extra-order piston. Plan the job on about 935 N of real work at 0.5 MPa rather than the full 1558 N rating.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MAC63X25SU Is Used
Accumulation stopper
Pops a stop blade up in a roller-conveyor accumulation zone, cushioning each carton impact at up to 800 mm/s cycle speed.
Checkweigher reject pusher
Shunts an underfilled bottle off the checkweigher belt into a reject bin, using the 25 mm kick and 1558 N push.
Case-packer carton stop
Stops and holds the leading carton of a magazine on a case packer until the bucket is in position, proven by a CMSG switch.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SU the Right Cylinder?
Size from the load: a 50 mm bore makes 981 N at 0.5 MPa and is the economical pick for lighter duty, while 1558 N push marks this 63 mm bore as the strongest the MA series offers. At 0.7 MPa it reaches 2181 N if you can spare the supply pressure.
The U flat-end back cover sits flush on a machine plate with no bracket, while CA pivot and CM round-end covers cover linkage and rod-ended installs, and FA flange, LB foot or SDB pivot brackets bolt on where needed. This is a plain double-acting cylinder - cut the air and the 25 mm stroke drifts wherever the load takes it, so add a pilot check valve or rod lock when the position must survive a power loss. CMSG, DMSG and EMSG switches mount directly on the standard magnet.
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 MAC63X25SU FAQ
The figures you need in one place: 1558 N push and 1457 N pull at 0.5 MPa; 2181 N push and 2040 N pull at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), piston speed 30-800 mm/s, variable cushion at both ends.
The U flat-end back cover bolts flat to a machine face, and FA flange, LB foot or SDB pivot brackets can be added; I and Y rod knuckles fit the M14x1.5 male rod thread. Air connects through the bore-standard 1/4 in ports.
