Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SCM 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 MAC63X40SCM
Packing 63 mm of bore into a 40 mm stroke, the MAC63X40SCM delivers 1557.9 N at 0.5 MPa from a riveted round barrel that stays sealed for life. Double acting throughout, it cushions both ends with variable needle screws, and the CM round-end cover provides a pivot point for swing clamps and toggle linkages.
Stainless tube plus a hard-chrome 16 mm rod means coolant splash, humid yards and outdoor fixtures are handled without paint to chip. Treat 935 N as your working force at 0.5 MPa and the piston seal - which stores its own grease - stays lively; in pure lift terms the rod manages about 159 kg, or a sensible 79 kg with a 2:1 margin. The magnet ships standard, ready for CMSG, DMSG or EMSG switches.

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 MAC63X40SCM Is Used
Swing-clamp fixture
Pivots a swing clamp on CNC jigs; the CM eye swings with the linkage and cushions the clamp-home.
Keg-rack ejector
Pushes filled keg racks sideways on brewery lines; the stainless body survives daily caustic washdown.
Header die kick-out
Ejects formed parts from a cold-header die in 40 mm with 2181 N behind it at 0.7 MPa supply.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X40SCM the Right Cylinder?
Choose this 63 mm short stroke when force per millimetre matters; the 50 mm bore (981.3 N push at 0.5 MPa) saves space if the 1000 N class is enough, and 32 mm (402.2 N) suits light clamping. Remember a pneumatic cylinder cannot park its load: on air loss the rod floats, so specify a rod lock or pilot check valve for held positions. Pair the CM pivot cover with LB foot, FA flange or SDB bracket hardware to suit the fixture.
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 MAC63X40SCM FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; 2181.0 N push and 2040.3 N pull at 0.7 MPa; 317.7 kgf theoretical at 1.0 MPa. Ports are 1/4", pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, stroke 40 mm.
Needle valves in both covers bleed trapped air to slow the piston over the final travel, so 2181 N-class impacts stop hammering the aluminium covers. Open both screws fully before the first stroke, then close them in small steps. For loads that must stay put on air failure, add a rod lock or pilot check valve - the cushion slows the piston, it never locks it.
