About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X220SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 220 mm stroke tasks. The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration. Its stainless barrel and piston rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
Equipped with a built-in magnet (-S), this unit supports CMSG, DMSG and EMSG reed or electronic switches for position sensing. Plan for about 147 N of actual work at 0.5 MPa, which means it can safely lift a 12.5 kg part vertically with a 2:1 safety margin. The rear CA pivot cover provides a clevis mount ideal for articulating loads, and air connects via a 1/8" port.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X220SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 220 mm stroke to shift parcels cleanly between parallel conveyor belts.
Textile Loom Tensioner
Provides consistent 245.3 N push at 0.5 MPa to maintain thread tension on a weaving machine, with the CA clevis allowing angular self-alignment.
Pallet Tag Applicator
Extends to press identification labels onto inbound pallets in a humid goods-in bay, relying on the stainless rod to resist washdown moisture.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X220SCA the Right Cylinder?
When sizing this 220 mm stroke unit, consider the neighbouring bores: a Ø20 generates 157 N of push at 0.5 MPa, while a Ø32 steps up to 402 N. This Ø25 strikes a solid balance for medium-force automation. Because the rod extends 220 mm, watch for side-load and rod-bending moments—ensure the load is guided to prevent premature seal wear. The included magnet pairs perfectly with CMSG, DMSG or EMSG sensors, and the rear CA clevis accommodates pivoting movements.
Remember that a standard double-acting cylinder like this will drift if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a locking brake. If your application requires strict position holding on air loss, add an external rod lock or a pilot-operated check valve to the system.
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 MI25X220SCA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches for position detection. The cylinder does not hold its load if air is lost; the fixed TPU bumpers only decelerate the stroke end. Use an external rod lock or pilot check valve for load holding.
