Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 650mm 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 MAC40X650SU
Long-travel duties rarely fit a catalogue stroke, and this one does not: the MAC40X650SU runs 650 mm on a 40 mm bore, built to order beyond the 500 mm standard limit. It is double acting, so air drives the rod in both directions, and a variable air cushion at each end soaks up shock over that full travel. Push force reaches 628 N at 0.5 MPa and 880 N at 0.7 MPa.
The riveted stainless barrel and 20 um hard-chrome rod shrug off washdown and damp air, a real edge over painted minis in food or outdoor lines. Working at roughly 60 percent of rating gives about 377 N of dependable push - enough to lift about 32 kg vertically with margin in hand. A magnet comes built in, so CMSG, DMSG or EMSG switches clip straight on without a special-order piston.

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 MAC40X650SU Is Used
Wide carton divert
A pusher sweeps cartons across a 600 mm-wide packaging conveyor lane in a single pass, cushions settling each sweep.
Tray lift into wash tunnel
Racks of machined parts rise into a wash tunnel on a vertical lift station sized inside the 32 kg vertical margin.
Paint booth slide door
A sliding door on a small paint booth opens 650 mm clear of spray in one stroke, driven at modest pressure.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SU the Right Cylinder?
Step down to a 32 mm bore for 402 N at 0.5 MPa, or up to 50 mm for 981 N if loads grow. Air enters through 1/8 in ports and the 16 mm rod carries an M12x1.25 thread. With no air the piston simply drifts - the cushion is not a brake - so hold suspended loads with a rod lock or pilot check valve. Over 650 mm of travel, external guiding matters: keep side load off the rod and align the tooling square. The U flat-end cover pairs with FA flange or LB foot mounts, and SDB pivot brackets are available.
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 MAC40X650SU FAQ
At 0.5 MPa this 40 mm bore pushes 628.3 N and pulls 527.8 N; at 0.7 MPa push climbs to 879.6 N. The theoretical peak at 1.0 MPa is 128.1 kgf. Keep supply inside 0.15-1.0 MPa (22-145 psi).
Both ends carry a variable air cushion. On first run back the needle screws fully off, then close them gradually until end-of-stroke thump disappears. Cycle speed can run anywhere from 30 to 800 mm/s on air filtered to 40 um.
