About the Airtac MIC Cushioned Mini Cylinder MIC40X500SU
Handling the heaviest tasks in the MIC range, this 40 mm bore round-body mini cylinder delivers a robust 628.3 N push force at 0.5 MPa. The stainless-steel barrel and piston rod resist mild corrosion and washdown environments, while the U-style back cover provides a 90-degree port orientation for tight machinery layouts. A 1/4" port feeds the double-acting piston, driving a 500 mm stroke at speeds between 30 and 800 mm/s.
Because this is the adjustable-cushion variant, needle valves at both ends let you dial in the exact deceleration to soak up end-of-stroke shock, protecting your payload and cutting noise compared to a fixed bumper. With a safe working load around 377 N, it lifts about 32 kg vertically using a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X500SU Is Used
Vertical Material Lift
Lifts roughly 32 kg payloads through the 500 mm stroke, relying on the adjustable cushion to prevent slamming at the bottom of the travel.
Heavy Package Diversion
Pushes dense cartons at high cycle rates using 628.3 N of thrust, with the needle-set cushion absorbing the repeated shock of sudden stops.
Washdown Actuation
Operates packaging machinery in damp or rinse-down zones thanks to the stainless steel construction, moving heavy gates with 879.6 N at 0.7 MPa.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X500SU the Right Cylinder?
At the top of the MIC sizing chart, this 40 mm bore leaves no larger option; if your load is lighter, step down to the 32 mm bore (402.2 N push @0.5 MPa). Choose this model specifically when moving heavier masses at high speed, where the adjustable air cushion is essential to prevent end-of-stroke impact. Remember the cushion only decelerates the piston near the end of travel; it is not a brake. If you need to hold a vertical load during air loss, add an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIC Cushioned Mini Cylinder MIC40X500SU FAQ
This double-acting cylinder has a 40 mm bore and uses a 1/4" port. The piston rod is 16 mm with an M12x1.25 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
Needle valves at both ends provide a variable air cushion to decelerate the piston smoothly before the end of the stroke, reducing shock at high speeds. The built-in magnet (-S) allows you to mount CMSG, DMSG, or EMSG sensors for position detection. The stainless build adds mild corrosion resistance.
