Airtac MAC Stainless Steel Mini Air Cylinder MAC63X55SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X55SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 55mm 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 MAC63X55SCA
The MAC63X55SCA is AirTAC's heavy end of the MA mini range: a 63 mm double acting round-body cylinder that pushes 1557.9 N and pulls 1457.4 N at 0.5 MPa, rising to 2181.0 N on extend at 0.7 MPa. A variable air cushion at both ends lets you bleed off end-of-stroke shock, so faster cycles or heavier loads stop quietly instead of hammering the covers.
Its stainless barrel and hard-chrome plated 16 mm carbon-steel rod shrug off washdown and damp air, an edge painted minis lack in food plants and outdoor fixtures. Budget about 935 N of working push at 0.5 MPa and the cylinder lifts roughly 79 kg vertically with a 2:1 margin. The magnet is fitted as standard, so CMSG, DMSG or EMSG switches click on without a special piston, and pressure spans 0.15-1.0 MPa (22-145 psi) with 30-800 mm/s speed.

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 MAC63X55SCA Is Used
Fixture clamp for tapping cast housings
With about 935 N of working push at 0.5 MPa, the cylinder clamps aluminium gearbox castings steady while a multi-spindle tapping head runs.
Counterbalanced oven door lift
A 2:1 margin gives close to 79 kg of vertical lift on 0.5 MPa air, enough to raise a loaded curing-oven lid on hinge-linked linkage.
Roller-line cart stop
The 1557.9 N extend force at 0.5 MPa parks 300 kg tooling trolleys dead at their index position, with the cushion absorbing arrival shock.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X55SCA the Right Cylinder?
Downsizing to a 50 mm bore saves space but the push falls to 981.3 N at 0.5 MPa, so stay at 63 mm when clamping near 900 N is needed. Remember a plain MAC holds nothing when air is lost - the rod drifts wherever the load takes it, so fit a pilot check valve or rod lock for parked loads. The CA pivot back cover here mates straight to clevis pins; FA flange, LB foot and SDB pivot brackets, plus I and Y rod knuckles, round out the mounting kit. Short 55 mm travel keeps side load a non-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 MAC63X55SCA FAQ
At 0.5 MPa this 63 mm bore pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa the figures are 2181.0 N push and 2040.3 N pull. Theoretical maximum is 317.7 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, port size is 1/4 inch and the rod thread is M14x1.5.
No. Every MA-series cylinder ships with the piston magnet already built in, so AirTAC CMSG, DMSG and EMSG switches mount directly onto the barrel without ordering a special piston or altering the 55 mm stroke.
