Airtac MAC Stainless Steel Mini Air Cylinder MAC40X600SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X600SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 600mm 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 MAC40X600SU
Where the body has to sit hard against a flat machine face, the MAC40X600SU fits: a 40 mm bore, 600 mm stroke MAC closed by a U flat-end back cover for direct fixed mounting. Double acting and cushioned at both ends, it pushes 628 N at 0.5 MPa; count on near 377 N for real work, matching a vertical lift of about 32 kg with margin. The 600 mm stroke is above the 500 mm bore-40 standard, so it is machined to order.
Its riveted stainless-steel barrel and 20 um hard-chrome rod take humidity, splash and outdoor exposure without the paint flaking that afflicts steel-bodied minis. A piston magnet comes fitted as part of the standard build, letting CMSG, DMSG or EMSG switches report rod position, and the twin needle-screw cushions tune out end-of-stroke bang at speeds of 30-800 mm/s.

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 MAC40X600SU Is Used
Bottling line bottle stopper
Stops and releases PET bottles ahead of the filler infeed, fixed flat to the conveyor frame with the U cover.
Weld cell tip dresser feed
Feeds the tip dresser into position on a robotic weld gun, cushioned to protect the dresser wheel.
Blister tray indexing push
Advances thermoformed trays through a printing and sealing station in a 600 mm index.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X600SU the Right Cylinder?
Lighter duty suits the 32 mm bore at 402 N push (0.5 MPa); heavier duty calls for the 50 mm bore at 981 N. Do not expect the cylinder to park its load: with the valve neutral or air off, the rod moves freely, so a rod lock or pilot check valve is the fix for held positions. On strokes this long, add an external guide or support the load to keep bending off the rod, and consider the SDB pivot bracket or FA flange if the flat-end mount alone does not suit the frame.
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 MAC40X600SU FAQ
Push at 0.5 MPa is 628 N and pull is 528 N; at 0.7 MPa push reaches 880 N, and the bore's theoretical peak is 128.1 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), with 1/8 inch ports and an M12x1.25 rod thread.
The U back cover presents a flat face that bolts directly against a machined surface, no bracket between body and frame. Both ends carry a variable air cushion controlled by needle screws: unscrew them fully at commissioning, then close in small steps until the 600 mm stroke lands quietly.
