About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200SULB
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 footprint. The 25 mm bore uses a 1/8" port and a 10 mm rod with an M10x1.25 male thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb impact at the stroke ends.
Because it carries an -S suffix, the piston includes a magnet for direct mounting of CMSG, DMSG or EMSG switches. For sizing real parts, plan for about 147 N of actual work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin. The U back cover provides a 90-degree port orientation, and the included LB foot bracket simplifies base mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200SULB Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 200 mm stroke to shift parcels cleanly between belts.
Vertical Parts Lift
Raises lightweight aluminium jigs between machine stations, easily handling the 12.5 kg safe vertical lift capacity.
Damp Environment Ejector
Pushes machined components out of a coolant-washed machining zone, relying on the stainless rod to resist mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200SULB the Right Cylinder?
This 25 mm bore sits comfortably in the range, stepping up from the 20 mm class (157 N push at 0.5 MPa) and offering a lighter alternative to the 32 mm class (402 N push at 0.5 MPa). The 200 mm stroke is well within the 500 mm maximum, though at full extension the 10 mm rod requires careful alignment to avoid side-loading and premature seal wear. The LB foot mounting and U back cover provide a stable 90-degree setup.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If air pressure drops or the valve is centred, the rod will drift and drop the load. To maintain vertical position safely, add an external rod lock or a pilot-operated check valve to the 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 MI25X200SULB FAQ
The 25 mm bore has a 1/8" port. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes. The -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG switches. It also uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder clevises and brackets.
