About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X235SR
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact riveted form. The Ø25 bore operates on a 1/8" port and features a male M10x1.25 rod thread. Because the -S suffix equips the piston with a magnet, you can directly mount CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
The stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. It conforms to ISO 6432 mounting dimensions for straightforward bracket integration. At 0.5 MPa, you can plan for a safe working load of roughly 147 N, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke extremes without adding adjustable cushioning complexity.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X235SR Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 245.3 N push force to deflect medium-weight cartons at high cycling speeds.
Lab Washdown Station
Extends a spray nozzle over a processing trough, where the stainless construction withstands frequent moisture and cleaning chemicals.
Vertical Parts Lift
Raises lightweight plastic totes 235 mm between conveyor tiers, safely managing loads near the 12.5 kg vertical lift threshold.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X235SR the Right Cylinder?
When sizing this 235 mm stroke model, verify your actual load against the 245.3 N push and 206.1 N pull figures at 0.5 MPa. If you need less force, the Ø20 bore provides 157.0 N of push, while stepping up to the non-ISO Ø32 bore yields 402.2 N. The 235 mm stroke is well within the 500 mm maximum for this bore, though at full extension you should minimize side-loading to prevent rod bending. The rear R cover provides an axial-in port orientation for tidy plumbing along the actuator axis.
Remember that a standard double-acting cylinder drifts when air pressure drops or the valve is centered, as the fixed TPU pads only decelerate the end-of-stroke impact rather than locking the load. To suspend a vertical weight safely, incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 MI25X235SR FAQ
This Ø25 bore cylinder features a 1/8" port and a male M10x1.25 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.
The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG switches. It uses fixed TPU bumper pads to decelerate at stroke ends; it does not have adjustable air cushioning, which is found on the MIC variant.
