About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial workloads within a compact footprint. The 25 mm bore pairs a 10 mm piston rod with a 1/8" port, while the built-in magnet (-S) directly supports CMSG, DMSG, and EMSG electronic or reed switches for precise end-of-stroke detection. Its CA rear clevis provides a robust pivot mount for angular motion requirements.
The stainless barrel and rod construction resists mild corrosion, making it well-suited for damp production areas where painted steel or aluminium bodies degrade. Plan for roughly 147 N of actual work at 0.5 MPa to maintain optimal performance, which translates to safely lifting about 12.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impacts, and because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185SCA Is Used
Package Diverter Arm
Utilizes the CA pivot clevis to swing a gating mechanism on a packaging line, reliably deflecting cartons weighing up to 12 kg at 0.5 MPa.
Press Ejector Station
Pushes stamped small metal components out of a die using 245.3 N of thrust, with the stainless body surviving splash coolant and ambient humidity.
Vertical Parts Lift
Raises lightweight plastic totes along a 185 mm vertical path, relying on the integrated magnet to trigger DMSG sensors at the upper transfer position.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185SCA the Right Cylinder?
When sizing this 25 mm bore unit, consider the adjacent options: a 20 mm bore generates 157.0 N of push force at 0.5 MPa, while stepping up to a 32 mm bore yields 402.2 N. This model occupies a strong middle ground for medium-force tasks. The 185 mm stroke is well within the 500 mm maximum standard stroke limit, though at this extension you should carefully manage side loading to prevent rod bending and premature seal wear.
The integrated -S magnet enables seamless position sensing with CMSG, DMSG, or EMSG switches. Remember that venting the air supply or centering the directional valve will cause the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. For suspended or gravity-loaded applications, install an external pilot-operated check valve or a dedicated rod lock.
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 MI25X185SCA FAQ
This 25 mm 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, 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, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not function as a brake. You must add an external rod lock or pilot check valve to maintain vertical position.
