Airtac MAC Stainless Steel Mini Air Cylinder MAC63X15SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X15SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 15mm 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 MAC63X15SU
Flat-ended and direct, the U back cover on the MAC63X15SU is made for rigid, bolted-on clamping. The 15 mm stroke concentrates full 63 mm bore force into a short hit: 1557.9 N push and 1457.4 N pull at 0.5 MPa, 2181.0 N at 0.7 MPa, 317.7 kgf theoretical at 1.0 MPa. Keep about 935 N for actual work after a sensible margin, and expect it to raise some 79 kg vertically at 2:1. Cushioning is adjustable air at both ends, so even this short stroke lands without a bang.
The riveted stainless barrel and hard-chrome rod shrug off coolant and cutting-fluid spray, a real edge over painted-steel mini cylinders around machine tools. Sensors cost nothing extra to enable - the magnet is already inside, so CMSG / DMSG / EMSG switches simply clip on. Operating window 0.15-1.0 MPa (22-145 psi) with air filtered to 40 um.

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 MAC63X15SU Is Used
CNC fixture booster clamp
Drives an auxiliary clamp on a milling fixture, holding aluminium plates against 2181.0 N at 0.7 MPa during facing cuts.
Go-no-go gate on a line
Blocks or releases parts between machining stations; 1457.4 N pull at 0.5 MPa snaps the gate back the instant the valve shifts.
Die-set locator lift
Raises a die-set corner by 15 mm for roller insertion - with the 2:1 margin the bore lifts about 79 kg vertically, enough for most small die shoes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X15SU the Right Cylinder?
Right-size first: a 40 mm bore pushes 628.3 N at 0.5 MPa if the 1557.9 N here is far more than needed, and 63 mm is the ceiling of the series. A plain double-acting cylinder will not keep the clamp closed when pressure is lost - order a rod lock or pilot check valve for that duty. The flat U cover bolts rigidly, or add FA flange, LB foot and SDB pivot brackets; the built-in magnet works with CMSG / DMSG / EMSG switches out of the box. Ports 1/4", rod thread M14x1.5.
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 MAC63X15SU FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. The cylinder works on 0.15-1.0 MPa (22-145 psi), travels 30-800 mm/s and uses 1/4" ports with an M14x1.5 rod thread.
The barrel is stainless steel riveted to aluminium covers and the 16 mm rod is hard-chrome plated, so coolant spray and humid shop air cause far less trouble than on painted-steel mini cylinders. Cushioning is variable air at both ends - back the needle screws off before the first run, then close gradually.
