Airtac MIC Cushioned Mini Cylinder MIC20X250U
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X250U is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 250mm 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 MIC20X250U
Built with a stainless-steel round barrel and rod, the MIC20X250U handles mild washdown environments while delivering a 157 N push force at 0.5 MPa. It features a 250 mm stroke, a 1/8 inch port, and a U-style rear cover for 90-degree mounting. This double-acting actuator conforms to the ISO 6432 mounting interface for standard mini-cylinder brackets.
A defining trait of this series is the adjustable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to eliminate high-speed shock and noise. For sizing, it provides a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X250U Is Used
Package Diverting
Uses the 157 N push force to rapidly deflect small cartons on a sorting line, relying on the cushion to stop the 250 mm stroke quietly.
Light Assembly Press
Moves a small tool head at high speed to seat components, using the adjustable cushion to prevent impact damage at the stroke end.
Bin Lid Actuation
Opens and closes access hatches in damp settings, benefiting from the stainless rod and barrel for mild corrosion resistance.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X250U the Right Cylinder?
When sizing this 20 mm bore, dropping down to an MIC16 lowers the 0.5 MPa push force to 100.5 N, while stepping up to an MIC25 raises it to 245.3 N. The adjustable cushion is essential if you are moving loads at high speed over the 250 mm stroke, as it protects the machinery far better than a fixed bumper.
Because this is a non-magnet SKU, position sensing is impossible without switching to the -S variant. Also, remember the air cushion only decelerates the piston near the end of travel; it does not act as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot check valve.
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 MIC20X250U FAQ
This 20 mm bore cylinder uses a 1/8 inch port and an M8x1.25 male rod thread. It generates a push of 157 N and pull of 131.9 N at 0.5 MPa. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The unit does feature a stainless build and adjustable air cushions at both ends to manage shock.
