About the Airtac MIC Cushioned Mini Cylinder MIC25X270SU
Engineered for high-speed actuation, the AirTAC MIC25X270SU features a needle-set variable air cushion at both ends to decelerate the piston smoothly, minimizing shock and noise compared to fixed bumper designs. This double-acting, round-body stainless-steel mini cylinder carries a 25 mm bore and a 270 mm stroke, yielding a push force of 245.3 N and a pull force of 206.1 N at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown environments.
Conforming to the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises. The 1/8" port and M10x1.25 male rod thread simplify integration. With a 0.5 MPa push force, it handles a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 safety margin. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG position sensing.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X270SU Is Used
Package Diverting
Uses the 245.3 N push force to deflect medium-weight cartons at high speed, relying on the adjustable air cushion to prevent harsh end-of-stroke impacts.
Component Seating
Presses lightweight bearings into stainless fixtures, where the 12.5 kg vertical lift capacity and needle-set deceleration protect delicate assemblies.
Flap Folding
Drives folding mechanisms on washdown-capable packaging lines, utilizing the 1/8" port and stainless construction for reliable pneumatic actuation.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X270SU the Right Cylinder?
When sizing this 245.3 N push class, stepping down to the MIC20 drops thrust to 157.0 N at 0.5 MPa, while stepping up to the MIC32 raises it to 402.2 N. The adjustable air cushion is essential when cycling heavy loads at high speeds up to 800 mm/s, as it absorbs end-of-stroke impact. Note that the cushion only decelerates the piston and does not lock or hold the load; if air pressure drops, the rod drifts, so add an external rod lock or pilot check valve for vertical safety.
The U back cover provides a 90-degree port and mounting orientation. You can mount the body using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions. Because this SKU includes the -S magnet, it fully supports CMSG, DMSG, and EMSG sensors for precise end-position detection.

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 MIC25X270SU FAQ
At 0.5 MPa, this double-acting cylinder provides a push force of 245.3 N and a pull force of 206.1 N. At 0.7 MPa, the push is 343.4 N and the pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa, and the air port size is 1/8".
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The adjustable air cushion only decelerates the piston near stroke end and does not act as a brake; for vertical loads, install an external rod lock or pilot check valve to prevent drifting on air loss.
