Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 250mm 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 MAC63X250SU
A 250 mm reach with over 1.5 kN behind it: the MAC63X250SU is a double-acting AirTAC MA-family mini cylinder whose 63 mm bore pushes 1558 N at 0.5 MPa and 2181 N at 0.7 MPa. Both ends carry a variable air cushion, so a heavy ejector arm can arrive at either end of the long travel without battering the covers.
The stainless round barrel and 20 um hard-chromed steel rod shake off washdown and outdoor damp far better than painted-steel minis, and the aluminium covers are rolled onto the tube in a riveted, sealed pack. It runs 30-800 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and every piston ships with its magnet already fitted, so CMSG, DMSG or EMSG switches clip straight on. For sizing, the 1558 N rating means about 935 N of honest pushing at 0.5 MPa - or, if the load hangs on the rod, roughly 79 kg lifted vertically with a 2:1 margin.

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 MAC63X250SU Is Used
Stamping die ejector
Kicks finished hinge blanks clear of a press die, using the 250 mm stroke to reach across the bolster and the 1558 N push to clear sticky parts.
Hopper slide gate
Opens and closes the slide gate on a batch-blending hopper; the variable cushion stops the 250 mm slam at both ends of the gate travel.
Palletiser squaring arm
Squares carton layers against a stop on a palletising conveyor, pushing with about 935 N of usable force at 0.5 MPa line pressure.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SU the Right Cylinder?
At 0.5 MPa this bore gives 1558 N push and 1457 N pull; the next size down, a 50 mm bore, manages only 981 N push at the same pressure, so step up to 63 mm whenever the load outgrows 50 mm. There is no bigger MA bore - 63 mm is the ceiling of the series, and anything beyond the 2181 N available at 0.7 MPa calls for a different cylinder family.
A 250 mm stroke is long for a mini body: guide the load externally, keep side load off the 16 mm rod, and remember the rod floats free when the valve centres or air is lost - a rod lock or pilot check valve holds a raised ejector in place. Order with FA flange or LB foot for a fixed line, SDB pivot for a swinging bracket; the standard magnet accepts CMSG, DMSG or EMSG sensing.
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 MAC63X250SU FAQ
At 0.5 MPa it pushes 1558 N and pulls 1457 N; raise the supply to 0.7 MPa and those figures become 2181 N push and 2040 N pull. The theoretical ceiling at 1.0 MPa is 317.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, with a variable air cushion at both ends.
Back both cushion needle screws fully off before the first stroke, then close them gradually until end-of-stroke shock over the long 250 mm travel disappears. Starting with the screws shut can stall the rod short of full stroke.
