Airtac MIC Cushioned Mini Cylinder MIC25X250SCA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X250SCA is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 250mm 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 MIC25X250SCA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X250SCA is a double-acting round-body mini cylinder built for demanding 250 mm stroke tasks. A variable air cushion at both ends lets you dial in the deceleration needle to absorb high-speed end-of-stroke shock, protecting your payload while cutting noise. The stainless-steel barrel and Ø10 mm piston rod shrug off mild corrosion and washdown environments. Because this Ø25 bore uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The integrated -S piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. From a practical sizing standpoint, this bore yields a safe working load of roughly 147 N, meaning it lifts about 12.5 kg vertically with a 2:1 safety margin. Air connects via a 1/8" port, and the CA rear cover provides a pivot mount for articulating loads. Remember that the cushion only decelerates the stroke; it does not lock the rod, so fit an external rod lock or pilot check valve if you need to hold a load on air loss.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X250SCA Is Used
High-Speed Diverting
Uses the 245.3 N push force to rapidly divert 12 kg cartons on a conveyor, relying on the adjustable air cushion to silently absorb the 250 mm stroke impact.
Pouch Sealing Press
Provides smooth, shock-free clamping on a packaging line where the stainless build resists washdown, and the CA pivot accommodates slight misalignment.
Articulated Lift Gate
Drives a small pivoting gate using the CA clevis mount, moving loads safely within the 147 N working limit while the ISO 6432 dimensions ease bracket sourcing.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X250SCA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa push) unit, step down to the Ø20 bore if your load is lighter, as it provides 157.0 N of push force. If you need more muscle, the Ø32 bore jumps to 402.2 N. The adjustable cushion is essential here if you are cycling at high speeds or moving heavy masses, preventing harsh impacts at the 250 mm stroke end. For mounting flexibility, you can use LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions alongside the built-in CA pivot cover.
Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly for end-of-stroke confirmation. A non-magnet version cannot take a sensor. Finally, never rely on the air cushion to hold a load vertically; it only decelerates the piston near the end of travel. If power drops, the rod drifts, so install a pilot-operated check valve for positive holding.
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 MIC25X250SCA FAQ
This double-acting cylinder features 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, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake. The rod will drift on air loss. You must use an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG/DMSG/EMSG sensors for position feedback.
