About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X480SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work over its 480 mm travel. The integrated piston magnet allows direct fitting of CMSG, DMSG or EMSG switches for position sensing, while the rear CA clevis accommodates pivoting loads. Its 1/8" port feeds the 10 mm rod to generate 343.4 N at 0.7 MPa.
The riveted stainless barrel and rod naturally resist mild corrosion, giving it an edge over painted alternatives in damp or washdown settings. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets. 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.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X480SCA Is Used
Pivot Diverter Gate
Swings a heavy sorting flap on a packaging line using the rear CA clevis, easily managing the 245.3 N push requirement to redirect cartons.
Product Lowering Arm
Lowers 12 kg fixture assemblies down a 480 mm vertical path, relying on the stainless construction to endure humid washdown environments.
Textile Loom Tensioner
Maintains precise tension on fabric threads during production, utilizing the built-in magnet and DMSG sensors to confirm material positioning.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X480SCA the Right Cylinder?
When sizing this 25 mm bore, the adjacent 20 mm option yields 157 N of push at 0.5 MPa, whereas stepping up to the 32 mm bore provides 402 N, making this model the sweet spot for medium-force tasks. The 480 mm stroke is well within the 500 mm maximum standard travel for this bore, though at this length you should carefully manage side loading to prevent rod bending and premature seal wear.
The fixed TPU bumper pads soften impact at the stroke ends but do not function as an adjustable air cushion; for high-speed energy absorption, consider the MIC variant. Because a standard cylinder vents and drifts when air is removed or the valve is centered, you must add an external rod lock or pilot check valve if the mechanism needs to hold a vertical load safely in place.
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 MI25X480SCA FAQ
This 25 mm bore cylinder features a 1/8" port and a 10 mm rod. 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.
No, the fixed TPU bumper pads only decelerate the piston at the stroke end and do not act as a brake. If air is lost or the valve is centered, the rod will drift. You must install an external rod lock or pilot-operated check valve to hold a suspended load.
