Airtac MIC Cushioned Mini Cylinder MIC25X40CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X40CA 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 MIC25X40CA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X40CA is a double-acting, round-body stainless steel mini cylinder built for demanding cycles. A needle-set adjustable air cushion at both ends absorbs end-of-stroke shock at high speeds, protecting the load and reducing noise far better than a fixed bumper. The stainless barrel and rod resist mild corrosion and washdown environments.
This Ø25 bore unit uses the ISO 6432 mini-cylinder mounting interface, dropping easily into standard brackets and clevises. It features a 1/8" port, an M10x1.25 male rod thread, and a CA rear pivot cover for direct clevis mounting. Without the -S magnet option, this specific SKU cannot accept CMSG, DMSG, or EMSG sensors. Based on the 0.5 MPa push force, it handles a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X40CA Is Used
High-Speed Diverting
Uses the 245.3 N push force to rapidly deflect packages on a conveyor, relying on the adjustable air cushion to silently absorb the 30-800 mm/s stroke impact.
Carton Flap Folding
Drives a folding arm at high speed to tuck flaps, where the needle-set cushion prevents jarring stops that would misalign light packaging materials.
Light Press Assembly
Applies a controlled 147 N safe working load to seat small bearings or pins, using the CA pivot mount to accommodate slight angular misalignment.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X40CA the Right Cylinder?
For sizing context, stepping down to the MIC20 bore drops the 0.5 MPa push force to 157 N, while moving up to the MIC32 raises it to 402 N. Choose this Ø25 model when your application requires that mid-range thrust at high cycling speeds where the adjustable air cushion is essential to prevent impact damage. Note that the cushion only decelerates the piston near the stroke end; it does not lock or hold the load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads.
The CA back cover provides a rear pivot point for angular movement. Because this SKU lacks the -S magnet, it cannot support position sensing; order the -S variant if you need to mount CMSG, DMSG, or EMSG switches. You can also adapt the mounting using LB foot, FA flange, SDB pivot, or TC trunnion accessories.
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 MIC25X40CA FAQ
This double-acting cylinder has a 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, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. 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 order the -S variant for position sensing. The adjustable air cushion at both ends only decelerates the load near stroke end; it is not a brake or lock.
