Airtac MIC Cushioned Mini Cylinder MIC25X40CM
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X40CM is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 40mm 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 MIC25X40CM
Built with a stainless-steel round barrel and rod, the AirTAC MIC25X40CM handles mild washdown environments while delivering 245.3 N of push force at 0.5 MPa. It uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. This 25 mm bore, 40 mm stroke double-acting actuator features a CM round rear cover and a 1/8" port.
A defining trait 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 high-speed impact, protecting the load and lowering machine noise. For sizing, this bore yields a safe working load of roughly 147 N and lifts about 12.5 kg vertically with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X40CM Is Used
Bottle Diverting
Snaps product across a belt at high speed. The tuned air cushion stops the 12.5 kg load gently without smashing the end cap.
Flap Folding
Drives carton flaps rapidly on a packaging line. The stainless build resists washdown, while the cushion prevents tearing the cardboard.
Small Part Ejection
Pushes machined parts out of a fixture. The 245 N thrust clears the part quickly, and the ISO 6432 body fits tight machine cells.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X40CM the Right Cylinder?
When sizing this 25 mm bore, dropping down to the MIC20 lowers the 0.5 MPa push force to 157 N, while stepping up to the MIC32 raises it to 402 N. Choose this 40 mm stroke model for short, rapid transfers where the adjustable air cushion is essential to prevent harsh end-of-stroke banging at speeds up to 800 mm/s. Mount it using LB foot, FA flange, SDB pivot, or TC trunnion hardware.
Keep in mind the cushion only decelerates the piston near the stroke end; it does not act as a brake. If air pressure drops, the rod will drift, so fit an external rod lock or pilot check valve to hold a suspended load. Because this specific SKU has no internal magnet, position sensing is not possible without switching 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 MIC25X40CM FAQ
This double-acting cylinder has a 25 mm bore, 40 mm stroke, 1/8" port, and an M10x1.25 male rod thread. 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 would need the -S variant for position sensing. The adjustable air cushions and stainless steel construction are still fully present.
