Airtac MAC Stainless Steel Mini Air Cylinder MAC63X90SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X90SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 90mm 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 MAC63X90SCA
Needing a pivoting mount on a big-bore mini? The MAC63X90SCA answers with a 63 mm barrel, 90 mm stroke, 1558 N of push and 1457 N of pull at 0.5 MPa. It is double acting with a variable air cushion at each end, so swing arms and linkages can cycle fast without slamming the covers.
The CA pivot back cover takes a clevis or pin directly, saving the bracket you would bolt onto a flat-ended body. Construction stays classic MAC: riveted stainless round barrel, aluminium-alloy covers and a 16 mm hard-chrome rod that copes with washdown and weather. The magnet is fitted as standard for CMSG / DMSG / EMSG switches, and budgeting the 1558 N push conservatively gives about 935 N of real work at 0.5 MPa - roughly a 79 kg vertical lift 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 MAC63X90SCA Is Used
Actuating aggregate hopper slide gates
1558 N at 0.5 MPa opens cast slide gates on aggregate and grain hoppers; the CA pivot eye matches the gate linkage pin-for-pin.
Extending dock-leveller lips
With about 79 kg of vertical lift at a 2:1 margin it swings dock-leveller lips, and the stainless barrel survives rain-exposed loading docks.
Ejecting offcuts from press trim dies
2181 N of push at 0.7 MPa clears stuck offcuts from trim dies on stamping presses; cushion tuning stops the ejector slamming at bottom dead centre.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X90SCA the Right Cylinder?
Against its neighbours, 63 mm is the ceiling of the cushioned mini range: a 50 mm bore manages only 981 N of push at 0.5 MPa, so scale up whenever your linkage multiplies the load. Air supply is 0.15-1.0 MPa (22-145 psi) of filtered air. The 90 mm stroke sits well inside the 500 mm standard limit, but check side load on swinging mounts - a loose clevis pin turns rod bending force up quickly. Remember the piston keeps moving once air is gone, so a rod lock or pilot check valve is the fix for held loads, and the standard magnet pairs with CMSG / DMSG / EMSG switches.
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 MAC63X90SCA FAQ
Push 1558 N and pull 1457 N at 0.5 MPa; push 2181 N and pull 2040 N at 0.7 MPa; 317.7 kgf maximum at 1.0 MPa. The port is 1/4 in., the 16 mm rod threads M14x1.5, and 90 mm sits inside the 500 mm standard stroke limit.
Yes - the pivot eye in the CA cover accepts a pin or clevis directly, so swinging linkages hook up without a separate bracket. For fixed frames, add the FA flange, LB foot or SDB pivot bracket instead.
