About the Airtac MIC Cushioned Mini Cylinder MIC25X450U
Handling mid-range actuation tasks, the AirTAC MIC25X450U relies on a variable air cushion at both ends to decelerate heavy 450 mm strokes smoothly. This double-acting, round-body stainless steel mini cylinder generates 245.3 N of push force and 206.1 N of pull force at 0.5 MPa. The needle-set cushions soak up high-speed kinetic energy, protecting your payload far better than a fixed rubber bumper. Its stainless barrel and rod resist mild corrosion and washdown environments.
Featuring a 25 mm bore, a 10 mm piston rod, and a 1/8" port, this unit conforms to the ISO 6432 mounting interface for straightforward bracket interchangeability. The integrated U back cover provides a 90-degree mounting orientation. It delivers a safe working load of roughly 147 N, meaning it lifts about 12.5 kg vertically with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X450U Is Used
Package Diversion
With a 450 mm stroke and 245 N of thrust, this cylinder reliably pushes medium cartons off a high-speed conveyor belt without slamming at the end of travel.
Vertical Lift Gate
Lifting a 12.5 kg access gate is well within its 2:1 safety margin, while the adjustable cushion prevents the heavy gate from crashing down at stroke end.
Component Ejection
Ejecting molded parts from a washdown-ready press station benefits from the stainless build and the needle-set cushions that absorb rapid ejection forces.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X450U the Right Cylinder?
When sizing this 25 mm bore unit, consider stepping down to an MIC20X50 class cylinder (157 N push at 0.5 MPa) for lighter loads, or up to an MIC32X50 class (402 N push at 0.5 MPa) if your thrust requirements exceed 245 N. The adjustable air cushion is essential here for a 450 mm stroke operating at high speeds, as it prevents harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston; it does not function as a lock or brake.
If your application must hold position during a compressed air loss, install an external rod lock or a pilot-operated check valve, because the piston will drift otherwise. This model features a U back cover for 90-degree mounting but ships without a magnet, meaning position sensing is unavailable unless you upgrade to the -S variant.
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 MIC25X450U FAQ
This 25 mm bore cylinder features a 1/8" port and a 10 mm rod. 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 of 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant for position sensing capabilities.
