Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MAC63X50SUH
At 63 mm bore and 50 mm stroke, the MAC63X50SUH gives you 1457.4 N of pull and 1557.9 N of push at 0.5 MPa, climbing to 2040.3 N and 2181.0 N at 0.7 MPa. It is fully double acting - compressed air moves the piston in both directions - and needle screws on each cap let you dial in the variable air cushion to soften end-of-stroke shock. The U back cover finishes in a flat machined face that mates directly with fixed mounting plates.
A rolled, riveted body clamps the aluminium-alloy covers tightly onto the stainless tube, while the 16 mm hard-chrome plated rod keeps sliding wear low over millions of cycles. Back the cushion needles fully off before the first run, then close them gradually until the deceleration suits your load. For sizing, count on close to 935 N of dependable push at 0.5 MPa - enough to raise a 79 kg part vertically with a 2:1 margin built in. A magnet ships inside every piston, ready for CMSG, DMSG and EMSG sensors.

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 MAC63X50SUH Is Used
Sluice gate control
Retracts a stainless sluice gate on a water-treatment channel; 1457.4 N of pull lifts the gate against head pressure and the end cushion stops travel without a bang.
Index lever drive
Flicks a four-position indexing lever on a rotary drill fixture; dual cushioning protects the 50 mm stroke at high cycle rates.
Machine guard lift
Raises an interlocked polycarbonate guard on a packaging machine; the standard magnet plus an EMSG switch confirms the guard is open before cycle start.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SUH the Right Cylinder?
A 40 mm bore only manages 628.3 N push at 0.5 MPa, so if your load sits under about 600 N step down; for anything beyond 1557.9 N this is already the largest MAC bore. Remember the piston is free to drift whenever air pressure drops or the valve centres - for a held load add a rod lock or pilot check valve. Mount via FA flange, LB foot or SDB pivot, and pair an I or Y knuckle with the M14x1.5 rod thread for linkage work. At 30-800 mm/s and this short stroke, side loading is rarely an issue.
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 MAC63X50SUH FAQ
At 0.5 MPa: 1557.9 N push and 1457.4 N pull. At 0.7 MPa: 2181.0 N push and 2040.3 N pull. Theoretical maximum force is 317.7 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure; use air filtered to 40 um and keep rod speed between 30-800 mm/s.
The MAC carries a variable air cushion at both ends, controlled by needle screws. Open the needles fully (backed off) before first pressurisation, run the cylinder slowly, then close each needle gradually until the load decelerates smoothly. This protects the covers and lets you run faster or carry heavier loads without hard impact.
