Airtac MIC Cushioned Mini Cylinder MIC20X70U
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X70U is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 70mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC20X70U
Damping high-speed strokes cleanly, the AirTAC MIC20X70U is a double-acting, round-body stainless-steel mini cylinder built for 20mm bores. Tuning the needle valve at each end lets you dial in the exact end-of-stroke deceleration, preventing load damage and cutting noise far better than a fixed bumper. The 1/8 inch port feeds an 8mm piston rod, pushing 157N and pulling 131.9N at 0.5MPa. This riveted stainless build resists mild corrosion and washdown, while the U-type rear cover provides a 90-degree mounting orientation.
In practical terms, this bore yields a safe working load of roughly 94N, letting you lift about 8kg vertically with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. Note that this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X70U Is Used
Package Diverting
Handles 8kg cartons at high cycle rates on a sorting line, using the adjustable cushion to softly stop the 70mm stroke without jarring the conveyor frame.
Small Press Fit
Pushes lightweight bearings or pins with 157N of force, relying on the needle-set damping to prevent impact damage at the bottom of the stroke.
Vertical Lift Gate
Raises and lowers an access flap, where the stainless barrel resists humidity and the 94N safe working load comfortably moves the lightweight panel.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X70U the Right Cylinder?
When sizing this 20mm bore against the rest of the MIC family, stepping down to the Ø16 version drops the 0.5MPa push force to 100.5N, whereas moving up to the Ø25 raises it to 245.3N. Choose this 70mm stroke model for mid-range thrust tasks where cycle speed is high enough that the adjustable air cushion is required to absorb kinetic energy. The cushion needle only decelerates the piston near the stroke end; it does not lock the rod. If your mechanism must hold a vertical load during air loss, install an external rod lock or a pilot-operated check valve. Mount it via the U-type back cover or LB, FA, SDB, and TC hardware, and remember this non-magnet SKU cannot host sensors.
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 MIC20X70U FAQ
This 20mm bore cylinder uses a 1/8 inch port and an 8mm rod with an M8x1.25 male thread. It pushes with 157N and pulls with 131.9N at 0.5MPa. At 0.7MPa, push increases to 219.8N and pull to 184.7N. The theoretical maximum force is 32kgf at 1.0MPa.
No, this specific SKU does not include an internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the MIC20X70U-S variant for sensing. The adjustable air cushion at both ends only serves to decelerate the load near stroke end, not to hold it in place.
