Airtac MAC Stainless Steel Mini Air Cylinder MAC40X540SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X540SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 540mm stroke, 1/8" 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 MAC40X540SCA
Where the standard 500 mm stroke ceiling falls short, the MAC40X540SCA fills the gap - its 540 mm stroke is produced to order rather than drawn from the standard range. The long 16 mm hard-chrome plated rod emerges from the same stainless round barrel and riveted covers as every MAC, with a CA pivot back cover ready for linkage duty.
Force figures are unchanged by the extra stroke: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N at 0.7 MPa, and a 128.1 kgf theoretical ceiling at 1.0 MPa. Treat about 377 N as the dependable working push and the bore will lift roughly 32 kg vertically. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, cushions adjustable at both ends.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X540SCA Is Used
Gantry reach extension
Extending a lightweight arm 540 mm to reach across a machine bed, external rails carrying the side load the long rod should not see.
Marking head lift
Raising a stamping head clear of tall workpieces between cycles, with end cushions softening both stops of the tall travel.
Deep-tray line transfer
Pushing deep bakery trays off the end of a line, the extra-long stroke clearing the full tray depth in one move.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X540SCA the Right Cylinder?
Size against neighbours: the 32 mm bore delivers 402 N at 0.5 MPa and the 50 mm bore 981 N, so 628 N sits between for mid-weight long-reach work. With 540 mm of rod out in the air, keep side loads off the rod and guide the load on external rails or bearings - the cylinder should push, not bend. Anchor with FA flange or LB foot brackets, add an SDB pivot where the mount swings, and remember the piston drifts if air is lost, so a rod lock or pilot check valve is needed for held loads. The 540 mm stroke is made to order.
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 MAC40X540SCA FAQ
No - bore sets force, not stroke. Expect 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, and 128.1 kgf theoretical at 1.0 MPa, on 0.15-1.0 MPa (22-145 psi) supply at 30-800 mm/s.
Standard MAC strokes for the 40 mm bore stop at 500 mm, so 540 mm is produced to order. Because over half a metre of rod is unsupported at full extension, guide the load externally and keep side loads off the rod to protect the barrel and seals.
