Airtac MAC Stainless Steel Mini Air Cylinder MAC63X35SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X35SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 35mm 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 MAC63X35SCA
Thirty-five millimetres of travel turns this 63 mm bore into a genuine short-stroke press: 1558 N pushing at 0.5 MPa, 2181 N when you feed it 0.7 MPa. The MAC63X35SCA is double acting with a variable air cushion either end, hung on a CA pivot back cover that lets the rod track a moving linkage. Keep the daily working force near 935 N - about 79 kg of vertical lift on a 2:1 margin - and the cylinder will outlive the machine around it.
Construction is the MA-family recipe done large: stainless tube rolled and riveted to aluminium end covers, a 20 um hard-chrome carbon-steel rod, and a two-way piston seal that carries its own grease film. Mild corrosion and washdown are non-events compared with painted-steel minis. The magnet is standard, so CMSG / DMSG / EMSG switches drop straight on; ports are 1/4", rod thread M14x1.5, speed 30-800 mm/s.

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 MAC63X35SCA Is Used
Scrap-chute gate actuation
Swings a foundry chute gate through 35 mm; the CA eye follows the gate arm while the cushion damps each slam.
Weld-fixture part kickers
Drops clamped brackets off a welding table with 1558 N at 0.5 MPa - enough to clear locating tabs without a kick-off cam.
Lab press for sample drums
Presses lids onto 20 L test containers between batches; stainless surfaces shrug off the rinse-down in between.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X35SCA the Right Cylinder?
If 35 mm is more travel than the task needs, a MAC63X20 saves dead space at the same 1558 N; if 628 N at 0.5 MPa is enough, a MAC40X35 costs less to run - 63 mm is the ceiling of the series at 317.7 kgf theoretical. Run it on 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air. A plain MAC will not hold position against gravity once air is lost, so add a rod lock or pilot check valve for any load that must stay put; the CA pivot suits linkages, while FA flange, LB foot or SDB pivot mounts adapt it to fixed frames.
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 MAC63X35SCA FAQ
At 0.5 MPa: 1558 N push, 1457 N pull. At 0.7 MPa: 2181 N push, 2040 N pull. Theoretical maximum 317.7 kgf at 1.0 MPa. Size the real job at about 935 N of push at 0.5 MPa so the cylinder keeps reserve.
Back both needle screws fully off before the first stroke, then close them gradually until end-of-stroke knock disappears. With the variable air cushion set, speeds from 30-800 mm/s stay smooth even at 0.7 MPa loads, and the standard magnet plus CMSG / DMSG / EMSG switches confirms position at each end.
