About the Airtac MIC Cushioned Mini Cylinder MIC20X500SU
Handling long 500 mm travels at high speed demands precise end-of-stroke control. The AirTAC MIC20X500SU is a double-acting, round-body stainless steel mini cylinder featuring needle-adjustable air cushions at both ends to decelerate heavy loads smoothly, reducing shock and noise far better than a fixed bumper. Its 20 mm bore generates 157 N of push force and 131.9 N of pull force at 0.5 MPa, making it a robust choice for mid-range actuation. This extended 500 mm stroke is a non-standard configuration, maximizing reach for compact machinery.
Built with a stainless-steel barrel and piston rod, this unit resists mild corrosion and washdown environments. It uses a 1/8" port and an M8x1.25 male rod thread. The -S suffix indicates a built-in piston magnet, allowing seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for position sensing. The U-style 90-degree rear cover provides flexible mounting orientation. Based on the 0.5 MPa push force, it handles a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X500SU Is Used
Extended Reach Diverters
Pushing packages across wider conveyor belts using the 500 mm stroke, relying on the 157 N push force and tuned air cushions to stop the diverter smoothly at high cycle rates.
Vertical Material Lifts
Raising light totes or bins up to 8 kg in pick-and-place racks, where the stainless build resists humidity and the adjustable cushion prevents sudden drops at the travel limit.
Long-Stroke Part Ejection
Ejecting molded or machined components from deep fixtures, using the 1/8" ported 20 mm bore to deliver rapid thrust while the needle-set cushion protects the part from impact damage.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X500SU the Right Cylinder?
When sizing this 20 mm bore unit, consider stepping down to the 16 mm bore (100.5 N push at 0.5 MPa) for lighter duties, or up to the 25 mm bore (245.3 N push at 0.5 MPa) if your payload exceeds the 94 N safe working load. The adjustable air cushion is essential here; at a 500 mm stroke running up to 800 mm/s, tuning the needle valve prevents harsh end-impact. Because this bore adheres to ISO 6432 mounting interface dimensions, it drops directly into standard mini-cylinder brackets and clevises.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake or lock. If air pressure drops, the piston will drift, meaning this cylinder cannot hold a vertical load safely on its own. For suspended loads, install an external rod lock or a pilot-operated check valve. Pair the U-style back cover with LB foot or FA flange mounts as needed, and utilize the -S magnet for non-contact sensing.
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 MIC20X500SU FAQ
This 20 mm bore cylinder uses a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa. Note that the 500 mm stroke is a non-standard length.
No, the adjustable air cushion only decelerates the piston near the end of the stroke; it is not a brake or locking mechanism. If air pressure is lost or the valve is centered, the piston will drift. For vertical loads, you must use an external rod lock or a pilot-operated check valve.
