About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CMLB
Generating 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 footprint. The 1/8" port feeds a Ø10 mm piston rod to deliver a 200 mm stroke. Built with fixed TPU bumper pads to absorb end-of-travel impacts, it operates smoothly across a 30-800 mm/s speed range. The CM round rear cover keeps the body clean for tight installations.
Because the stainless barrel and rod resist mild corrosion, this unit outlasts painted alternatives in damp or washdown settings. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. 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. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to an -S variant.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CMLB Is Used
Packaging Diverter
Pushes heavy cardboard cartons at 245.3 N on a packaging line, using the 200 mm stroke to reroute boxes into secondary lanes.
Lab Washdown Station
Actuates a rinsing nozzle in a damp laboratory environment, leveraging the stainless steel barrel to resist mild corrosion and chemical mist.
Pallet Load Stop
Halts incoming pallets on a low-profile conveyor, absorbing the impact via fixed TPU bumper pads before the 200 mm retraction resets the gate.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CMLB the Right Cylinder?
When sizing this 25 mm bore, stepping down to a Ø20 unit drops the 0.5 MPa push force to 157 N, while moving up to a Ø32 bore raises it to 402 N. The included LB foot bracket secures the cylinder base, while the CM round back cover offers a clean rear profile. For this 200 mm stroke, ensure your front mounting guides the load to prevent rod bending and premature seal wear. Remember that venting the air causes the piston to drift; the TPU bumpers only soften the stroke end rather than locking the rod. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MI25X200CMLB FAQ
This 25 mm bore cylinder features a 1/8" 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.
Yes, it uses ISO 6432 mounting dimensions so it fits standard mini-cylinder clevises and brackets, and it includes an LB foot bracket. However, this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG or EMSG switches; you would need the -S variant for position sensing.
