Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 150mm 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 MAC63X150SU
At Dia 63 this is the muscle end of the MAC family: 1557.9 N push and 1457.4 N pull at 0.5 MPa, climbing to 2181.0 N at 0.7 MPa, with a 317.7 kgf theoretical maximum at 1.0 MPa. The 150 mm stroke moves a real work face - expect it to lift about 79 kg vertically on a 2:1 margin, and plan around 935 N of usable work force at 0.5 MPa. Double acting with a variable air cushion at both ends, it runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and the needle screws let you tune deceleration so fast travel does not hammer the covers.
The round barrel is stainless steel rolled onto aluminium covers, with a hard-chrome plated rod - a build that tolerates damp shop air where painted mini cylinders blister. The magnet is built in as standard, so CMSG / DMSG / EMSG switches clamp on for end-of-stroke signals. The U flat-end back cover takes a fixed mount straight away; FA flange, LB foot or SDB pivot brackets can be added where the machine needs them.

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 MAC63X150SU Is Used
Press die-cart pusher
Shoves a die cart into a stamping press over the 150 mm stroke; 1557.9 N push at 0.5 MPa keeps the move going even with sticky rails.
Cheese-brine hatch actuator
Opens stainless hatch doors in a washdown zone where painted cylinders corrode; the riveted stainless barrel shrugs off the daily spray.
Case-eject kicker
Knocks 60-70 kg cases off a palletising conveyor - with the 2:1 margin this bore lifts about 79 kg vertically, so the kick is decisive.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SU the Right Cylinder?
Size it both ways: a 50 mm bore still gives 981.3 N push at 0.5 MPa if the 1557.9 N of the 63 mm is oversize, and 63 mm is the largest bore in the MAC series - nothing bigger exists to step up to. A plain double-acting cylinder lets the piston drift as soon as air drops or the valve centres, so fit a rod lock or pilot check valve if the load must stay put. Keep side loads off the 16 mm rod over the 150 mm stroke and guide the load externally. Ports 1/4", rod thread M14x1.5; FA flange, LB foot and SDB pivot brackets all fit if the U flat-end cover alone is not enough.
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 MAC63X150SU FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa the push reaches 2181.0 N and the pull 2040.3 N, with a 317.7 kgf theoretical maximum at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the bore is fed through 1/4" ports with an M14x1.5 rod thread.
The MAC carries a variable air cushion at both ends, not a fixed bumper. Back both needle screws fully off before the first run, then close them gradually until end-of-stroke shock disappears - worth doing carefully with 150 mm of travel at up to 800 mm/s.
