Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100CAH
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100CAH is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 100mm 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 MI25~40 Stainless Steel Mini Cylinder MI25X100CAH
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust 100 mm stroke tasks. The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration. Its riveted stainless barrel and Ø10 rod shrug off mild corrosion better than painted alternatives in damp or washdown environments. Equipped with a CA pivot clevis and high-temperature Viton seals, it is built for hotter operating zones.
Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. Plan for a safe working load of roughly 147 N, which lets you lift about 12.5 kg vertically with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors; order an -S variant if position feedback is required.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100CAH Is Used
Diverting Hot Packages
Uses the CA clevis to pivot a diverter arm on a packaging line, relying on Viton seals to withstand ambient heat from nearby heat-shrink tunnels.
Press Ejection
Pushes small stamped parts out of a die with 245.3 N of force at 0.5 MPa, using the 100 mm stroke to clear the tooling envelope completely.
Damp Environment Gating
Actuates a stainless-steel flow gate in a washdown food processing area, where the riveted stainless barrel resists mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100CAH the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit against the family, the smaller Ø20 bore provides 157.0 N of push, while the larger Ø32 bore jumps to 402.2 N. Choose this Ø25 model when your load sits right in that middle band. The integrated CA rear pivot cover is ideal for clevis mounting, and the Viton -H seals accommodate elevated thermal demands.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered, as the TPU bumpers only decelerate the end of travel rather than locking the rod. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, a 100 mm stroke on a Ø10 rod can invite side-loading, so ensure your front mounting guides the load cleanly to prevent rod bending.
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 MI25~40 Stainless Steel Mini Cylinder MI25X100CAH FAQ
This Ø25 bore cylinder features a 1/8" air 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, because this specific SKU lacks the -S magnet option, it cannot support CMSG, DMSG or EMSG magnetic switches. You would need to select an -S variant of the MI series to enable sensing capabilities.
