About the Airtac MIC Cushioned Mini Cylinder MIC25X30SU
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X30SU is a double-acting, round-body stainless steel mini cylinder built for high-speed actuation. Its defining feature is the adjustable air cushion at both ends, allowing you to dial in a needle valve to absorb end-of-stroke shock, protecting your payload and reducing noise far better than a fixed bumper. The stainless barrel and rod resist mild corrosion and washdown environments, while the U-style back cover provides a 90-degree mounting orientation. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG position switches.
At this bore size, the cylinder generates a safe working load of roughly 147 N and can lift about 12.5 kg vertically with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for drop-in compatibility with standard mini brackets. The 1/8" port and M10x1.25 male rod thread ensure robust pneumatic and mechanical connections across its 30 mm stroke. It operates between 0.15 and 1.0 MPa, reaching speeds of 30-800 mm/s.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X30SU Is Used
Package Diverting
Snaps a lightweight routing gate at high speed on a sorting line, using the adjustable cushion to softly stop the 30 mm stroke and prevent parcel damage.
Flap Folding
Drives a carton flap tucker at 800 mm/s, relying on the 245 N push force and needle-set deceleration to fold cardboard without slamming the fixture.
Lab Sample Ejection
Pushes prepared samples out of a testing carousel, where the stainless build resists chemical mist and the cushioning protects delicate glassware.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X30SU the Right Cylinder?
When sizing this 25 mm bore, stepping down to the MIC20 drops the 0.5 MPa push force to 157 N, while stepping up to the MIC32 raises it to 402 N. The adjustable cushion matters most when driving heavier loads at high velocities, as it prevents harsh impacts at the 30 mm stroke ends. For position sensing, the -S magnet enables CMSG, DMSG, and EMSG switches; a SKU without the S cannot take a sensor. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
Remember that the air cushion only decelerates the piston near the stroke end; it is not a brake. If air pressure drops, the piston will drift, meaning this cylinder does not hold position or load on air loss. For applications requiring a held load, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MIC25X30SU FAQ
This double-acting cylinder has a 25 mm bore, a 1/8" port, and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa.
Yes, the -S designates a built-in piston magnet for CMSG, DMSG, or EMSG switches. The adjustable air cushion at both ends uses a needle valve to trap exhaust air, decelerating the load smoothly at stroke end. It is a dampener, not a lock.
