Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 40mm 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 MAC63X40SU
A riveted stainless round barrel with a hard-chrome plated rod gives the MAC63X40SU a real edge over painted-steel minis in wet or dusty plants: mild corrosion and washdown simply do not bite. It is double acting - compressed air both extends and retracts the rod - and a variable air cushion at each end can be dialed in to soften stops. From a 63 mm bore that means 1557.9 N of push and 1457.4 N of pull at 0.5 MPa.
Over a short 40 mm stroke that force adds up to serious punch: treat 935 N as the useful working level and you leave margin for pressure dips. In lifting terms that is about 79 kg held vertically with a 2:1 margin - a loaded food tray stack or a small fixture. The U flat-end back cover sits flush against a fixed face with no extra bracket, and the built-in magnet is standard, so CMSG / DMSG / EMSG switches drop straight on.

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 MAC63X40SU Is Used
Bushing press-fit
Presses bronze bushings into gearbox housings on a small assembly bench - 935 N of working force over a 40 mm stroke is enough for light interference fits.
Mold side clamp
Clamps a slide core on a small injection mold, where the washdown-safe stainless barrel copes with mold-release mist and coolant spatter.
Washdown lid clamp
Holds a hopper lid shut on a spice-blending line, where daily hose-downs would ruin a painted-steel mini cylinder.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SU the Right Cylinder?
The 63 mm bore is the top of the MAC range; if 935 N of usable push is more than the job needs, bore 50 delivers 981.3 N at 0.5 MPa and saves air. For fixed-face mounting the U flat-end cover is already the right choice; FA flange or LB foot brackets bolt on when the frame needs them. Note that a plain MAC drifts if air is lost or the valve centres - the cushion damps impact, it does not lock the rod - so fit a rod lock or pilot check valve where a load must be held.
At 40 mm stroke side loading is rarely an issue, but keep the M14x1.5 rod coupling concentric anyway and run speed between 30 and 800 mm/s; pressure window is 0.15-1.0 MPa (22-145 psi).
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 MAC63X40SU FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa those figures rise to 2181.0 N push and 2040.3 N pull. The theoretical maximum at 1.0 MPa is 317.7 kgf. Ports are 1/4 inch, the rod is 16 mm with an M14x1.5 male thread, and speed runs 30-800 mm/s.
No - the U flat-end back cover seats directly against a fixed machine face, so a plain through-bolt often replaces a bracket. If the design later needs a flange or foot, FA and LB accessories fit the same barrel, and the standard magnet already supports CMSG / DMSG / EMSG switches.
