Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 50mm 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 MI25X50SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder tackles heavier duty cycles where smaller bores stall. The Ø25 mm bore uses a 1/8" port and a Ø10 mm rod with an M10x1.25 male thread. Because the piston carries a magnet, you can mount CMSG, DMSG or EMSG switches for end-of-stroke confirmation. Riveted stainless construction shrugs off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
In practical terms, plan for a safe working load of roughly 147 N rather than pushing the absolute limit. That translates to lifting about 12.5 kg vertically with a 2:1 safety margin, letting you match the cylinder to real part weights. The CA rear cover provides a pivot clevis for articulated mounting, while fixed TPU bumper pads absorb the impact at stroke ends. The unit conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCA Is Used
Clamp and Rivet Station
Holds an automotive bracket steady against a riveting head, using the 245.3 N push force to prevent deflection during the fastener setting process.
Pallet Diverter Arm
Swings via the CA clevis to knock misaligned cartons off a packaging line, relying on the stainless body to survive daily washdowns.
Vertical Parts Lift
Raises 12.5 kg trays of machined components between conveyor tiers, using position feedback from a DMSG sensor triggered by the internal magnet.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCA the Right Cylinder?
Sizing around this 245.3 N @0.5 MPa unit means checking your neighbours: step down to a Ø20 bore for 157.0 N if the load is lighter, or jump up to a Ø32 bore for 402.2 N when resistance spikes. This CA-clevis model pivots to absorb misalignment, which is useful since a 50 mm stroke keeps side-load risk low but does not eliminate it. If your process drops air or centres the valve, the piston will drift; these bumpers only soften the end-of-stroke impact, so fit an external rod lock or pilot check valve to suspend a load safely.
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 MI25X50SCA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa those figures rise to 343.4 N push and 288.5 N pull, with a theoretical maximum of 50 kgf at 1.0 MPa. The air port is 1/8".
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and act as neither a brake nor a lock. You must use an external rod lock or pilot-operated check valve to hold a load safely.
