About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 375 mm travel tasks. The Ø25 mm bore uses a 1/8" port and a sturdy Ø10 mm piston rod. Riveted stainless construction resists mild corrosion and washdown, offering a real edge over painted alternatives in damp environments. Fixed TPU bumper pads absorb the impact at stroke extremes, operating reliably across a 30-800 mm/s speed range.
Because the -S suffix equips the piston with a magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. The CA rear cover provides an integrated pivot clevis for angular alignment. For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a safe 2:1 margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375SCA Is Used
Diverting Gate Actuation
Uses the 245.3 N push force at 0.5 MPa to pivot heavy sorting flaps on packaging conveyors, with the CA clevis accommodating the arc.
Product Pressing Station
Lowers a heated platen over 375 mm to seal cartons, relying on the stainless body for resistance in washdown zones.
Pallet Tag Applicator
Extends to press identification labels onto pallets, using the -S magnet and DMSG switches to confirm full extension.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375SCA the Right Cylinder?
This 375 mm stroke sits well within the 500 mm maximum standard stroke for the Ø25 bore, making it a regular catalogue choice rather than a special order. When sizing, the smaller Ø20 bore yields 157.0 N push at 0.5 MPa, while the larger non-ISO Ø32 bore jumps to 402.2 N. If your application loses air or centres the valve, this cylinder will drift; the bumpers only decelerate the end of travel and act as neither a brake nor a lock. To suspend a load securely, add an external rod lock or a pilot-operated check valve.
The CA pivot clevis pairs with the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets. A 375 mm stroke generates leverage, so verify your side-load geometry to prevent rod bending and premature seal wear.
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 MI25X375SCA FAQ
This Ø25 mm bore cylinder features a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; the piston will drift if air is lost, requiring a pilot check valve for holding. The CA designation indicates a rear pivot clevis that allows angular movement, and the -S magnet enables CMSG, DMSG or EMSG sensors.
