About the Airtac MIC Cushioned Mini Cylinder MIC25X40U
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder is built for rapid cycling. The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb shock and reduce noise at high speeds, outperforming fixed bumper designs. The stainless barrel and piston rod provide mild corrosion resistance for washdown environments, and the unit conforms to ISO 6432 mounting dimensions for Ø25 bores.
This specific configuration uses a 40 mm stroke with a U-style 90-degree rear cover for versatile porting and mounting. It features a 1/8" port and an M10x1.25 male rod thread. Based on the 0.5 MPa push force, the computed safe working load is approximately 147 N, translating to a vertical lift capacity of about 12.5 kg with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X40U Is Used
Package Diverting
Uses the 245.3 N push force to swiftly reroute small to medium parcels on a high-speed sorting line, relying on tuned air cushions to prevent harsh slamming at the 40 mm stroke end.
Carton Sealing
Drives sealing flaps on automated packaging equipment where rapid repetitive motion demands shock absorption to protect the mechanical joints and maintain cycle speed.
Light Pressing
Applies safe clamping pressure for assembling small plastic components, utilizing the 12.5 kg vertical lift margin without damaging delicate parts thanks to adjustable deceleration.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X40U the Right Cylinder?
When sizing this 25 mm bore, stepping down to the MIC20 drops the 0.5 MPa push force to 157.0 N, while stepping up to the MIC32 raises it to 402.2 N. Choose this 245.3 N model when moving moderate masses at high cycle rates where the adjustable air cushion is essential to prevent end-of-stroke impact. The cushion needle only decelerates the load near the stroke end; it does not function as a lock or brake. If your application must hold position on air loss, add an external rod lock or pilot-operated check valve.
The U-style back cover simplifies 90-degree mounting orientations. Because this specific SKU is non-magnetic, it cannot support sensing switches. If you need position feedback, select the -S magnet variant to enable CMSG, DMSG, or EMSG sensors.
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 MIC25X40U FAQ
This 25 mm bore cylinder has a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it provides 245.3 N push and 206.1 N pull force. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 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 choose the -S variant for position sensing. The adjustable air cushions at both ends only serve to decelerate the load near stroke end and do not lock or hold the piston in place.
