Airtac MIC Cushioned Mini Cylinder MIC25X85SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X85SU is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 85mm 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 MIC25X85SU
Dial in end-of-stroke deceleration with the AirTAC MIC25X85SU, a double-acting round-body mini cylinder built around a stainless-steel barrel and Ø10 mm rod for mild washdown resistance. A variable air cushion at both ends lets you needle-set the exhaust bleed to absorb high-speed impact, protecting your payload far better than a fixed rubber bumper. The U-style back cover provides a 90-degree port and mounting orientation for tight spatial constraints.
Generating 245.3 N of push and 206.1 N of pull at 0.5 MPa, this bore class hits a useful mid-range force. Based on the 0.5 MPa push figure, it handles a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 safety margin. The integrated -S piston magnet allows direct mounting of CMSG, DMSG or EMSG switches for position sensing, and the body conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X85SU Is Used
Package Diverter
Pushes light cartons at high cycle rates. The adjustable air cushion prevents harsh impacts at the 85 mm stroke end, protecting the diverter arm.
Small Press Ejection
Provides 245 N of push to eject stamped parts. The stainless build resists cutting fluid mist, while the magnet enables part-out confirmation.
Vertical Lift Gate
Lifts roughly 12.5 kg access gates. The cushion softens the descent, though a pilot check valve must be added to hold the load during air loss.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X85SU the Right Cylinder?
When sizing this 25 mm bore, step down to an MIC20 (157 N push @0.5 MPa) for lighter loads, or move up to an MIC32 (402 N push @0.5 MPa) if you need significantly more thrust. The adjustable air cushion is essential when cycling at high speeds or moving heavy masses, as it prevents harsh end-of-stroke slamming. Because this is a double-acting cylinder, it does not hold position on air loss—the piston drifts, so add an external rod lock or pilot check valve for suspended loads.
The 1/8" port matches the standard 25 mm bore airflow requirements. Thanks to the -S suffix, position sensing is ready out of the box with CMSG, DMSG or EMSG switches. Mounting flexibility extends beyond the U cover via LB foot, FA flange, SDB pivot and TC trunnion accessories.
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 MIC25X85SU FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The variable air cushion at both ends uses a needle valve to trap and bleed exhaust air, decelerating the piston near stroke end to reduce shock. It is a deceleration device, not a brake.
