About the Airtac MIC Cushioned Mini Cylinder MIC25X375SU
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X375SU is a double-acting round-body mini cylinder built for demanding motion tasks. It features a stainless-steel barrel and piston rod that resist mild corrosion and washdown environments. Because this Ø25 bore adheres to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises without custom hardware.
The defining feature of the MIC series is the adjustable air cushion at both stroke ends. By turning a needle valve, you tune the deceleration to absorb high-speed shock, protecting your payload and cutting impact noise. This specific configuration includes a built-in piston magnet for position sensing and a U-style 90-degree rear cover for flexible port and mounting orientation. With a 1/8" port and a 375 mm stroke, it provides a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X375SU Is Used
High-Speed Diverting
Uses the 245.3 N thrust to push packages off a belt at speed, relying on the tuned air cushion to stop the rod softly without slamming the diverting arm.
Controlled Lowering
Lifts and lowers a 12.5 kg tooling head vertically, using the adjustable end cushion to prevent a hard impact at the bottom of the 375 mm stroke.
Flap Folding
Drives a carton flap folder on a washdown packaging line where the stainless rod and barrel provide necessary mild corrosion resistance.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X375SU the Right Cylinder?
When sizing this 25 mm bore, compare it directly against adjacent models. Dropping down to a Ø20 MIC bore reduces your 0.5 MPa push force to 157 N, while stepping up to a Ø32 MIC bore increases it to 402 N. Select this unit when your cycle speed pushes the 30-800 mm/s range and a fixed bumper would transmit too much shock to the load. The adjustable cushion lets you dial in the exact end-of-stroke deceleration required.
Remember that the air cushion only decelerates the piston near the end of travel; it does not function as a brake or lock. If your application must hold a vertical load during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. This SKU includes the -S magnet for CMSG, DMSG, or EMSG switches, and pairs with LB, FA, SDB, or TC mounts.
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 MIC25X375SU FAQ
This 25 mm bore cylinder uses a 1/8" port and a male M10x1.25 rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The adjustable air cushion at both ends uses a needle valve to restrict exhaust air, decelerating the piston at stroke end to reduce shock. It is not a locking brake.
