Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 400mm 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 MAC63X400SCM
Round in section and riveted tight, the MAC63X400SCM pairs a 63 mm bore with a 400 mm stroke in a stainless-steel barrel that shrugs off washdown and damp plant air. It is double acting - air extends and retracts the rod - with a variable air cushion at each end to soak up shock, so you can push 1557.9 N at 0.5 MPa (2181.0 N at 0.7 MPa) and still stop clean. The CM round-end back cover gives a pivot eye that swings without added brackets.
At 0.5 MPa the rod pushes about 1557.9 N and pulls 1457.4 N; keep real work near 935 N and the cylinder will outlast any rating-sheet duty. On vertical lifts that is roughly 159 kg of rod force, or about 79 kg when you keep a 2:1 margin. A magnet comes built in as standard, so CMSG, DMSG or EMSG switches clip straight on for end-of-stroke signals.

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 MAC63X400SCM Is Used
Pallet densifying press
A 400 mm stroke at 935 N of working force compacts stretch wrap and carton overhang before strapping.
Conveyor plough actuator
Swings a divert plough across a wide conveyor lane; the CM pivot eye follows the linkage arc without extra knuckles.
Case-sealing press head
Presses lids home on 60-litre dairy crates at line speed, with cushioned landings at both ends of the stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCM the Right Cylinder?
Need less force? The 50 mm bore delivers 981.3 N push at 0.5 MPa; step beyond 63 mm and you leave the MA mini family. At 400 mm stroke keep side loads off the 16 mm rod or guide the load externally, and remember the piston drifts when air is lost - fit a rod lock or pilot check valve if position must be held. LB foot or FA flange mounts plus the CM round-end pivot cover suit most frames; the magnet is standard for CMSG / DMSG / EMSG switching.
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 MAC63X400SCM FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa that rises to 2181.0 N push and 2040.3 N pull. Theoretical maximum is 317.7 kgf at 1.0 MPa. Ports are 1/4", the rod is 16 mm with M14x1.5 male thread, and supply pressure spans 0.15-1.0 MPa (22-145 psi).
No - every MAC63X400SCM ships with a built-in magnet, so CMSG, DMSG and EMSG reed or solid-state switches mount directly on the stainless barrel without a special piston. Run the cylinder at 30-800 mm/s and back the cushion needles off before the first stroke.
