About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in tight spaces. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors.
Plan for roughly 147 N of actual work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a safe 2:1 margin. The riveted body keeps the unit compact, while fixed TPU bumper pads absorb stroke-end impact. The CA rear cover provides a pivot clevis for articulated mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70SCA Is Used
Package Diverting Gate
Pivots a sorting flap on a packaging line, using the CA clevis to articulate and the 245 N thrust to push heavy cartons smoothly.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, taking advantage of the 12.5 kg vertical lift capacity to hold parts firmly.
Pallet Stopper Arm
Deploys a stopping lug on a roller conveyor, relying on the stainless build to endure humid warehouse environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70SCA the Right Cylinder?
If 245.3 N at 0.5 MPa is too much, step down to the Ø20 bore (157 N push); if you need more power, the Ø32 bore offers 402.2 N. Because this SKU includes the -S magnet, you can mount CMSG or DMSG switches directly for end-position detection. The CA back cover supplies a rear pivot point for clevis mounting.
Remember that a plain cylinder drifts when air is lost or the valve centers—the TPU bumpers only soften the stroke end and do not act as a lock. To hold a load securely mid-stroke, add an external rod lock or a pilot-operated check valve. The 70 mm stroke is well within standard limits, keeping side-load stress low.
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 MI25X70SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. It does not hold position on air loss; the fixed TPU bumpers only decelerate the stroke end. Use an external rod lock for holding.
