Airtac MIC Cushioned Mini Cylinder MIC25X300U
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X300U is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 300mm 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 MIC25X300U
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X300U is a double-acting, round-body stainless-steel mini cylinder built for a 300 mm stroke. Its defining feature is the adjustable air cushion at both ends, letting you tune a needle valve to decelerate heavy loads smoothly and cut end-of-stroke noise at high cycling speeds. The stainless barrel and rod provide mild corrosion resistance for washdown environments, while the U-style back cover provides a 90-degree port and mounting orientation.
This Ø25 bore conforms to the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 safety margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. It uses a 1/8" port and an M10x1.25 male rod thread.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X300U Is Used
High-Speed Diverting
Ideal for rapidly pushing light packages on a conveyor at 30-800 mm/s, using the adjustable air cushion to silently absorb the shock of frequent direction changes.
Carton Flap Folding
Provides the 245.3 N push force needed to fold heavy cardboard flaps during case erecting, with the U-style rear cover allowing tight 90-degree mounting in compact machinery.
Lab Washdown Station
The stainless steel barrel and rod withstand mild corrosive cleaning agents, while the 300 mm stroke precisely raises and lowers equipment racks into washing position.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X300U the Right Cylinder?
When sizing this model, consider the next bore down and up. Dropping to the Ø20 MIC lowers the 0.5 MPa push force to 157 N, while stepping up to the Ø32 MIC increases it to 402.2 N. The adjustable cushion is essential if you are driving the 300 mm stroke at high speeds or moving the maximum 12.5 kg vertical load, as it prevents harsh mechanical impacts. The cushion only decelerates the piston near the stroke end; it does not act as a brake.
Because this is a plain double-acting cylinder without a -S magnet, it cannot support position sensing switches. If your application requires the piston to hold its place during a sudden air loss or valve centering, you must add an external rod lock or a pilot-operated check valve, as the cylinder will drift. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MIC25X300U FAQ
This double-acting cylinder has a 25 mm bore and 300 mm stroke. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, and 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. It features a 1/8" port and an M10x1.25 male rod thread.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The adjustable air cushions at both ends function to decelerate the load, not to hold position.
