About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work over a 450 mm stroke. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration. Its stainless barrel and rod resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of an adjustable cushion.
Because this specific SKU lacks the -S magnet suffix, it cannot host CMSG, DMSG, or EMSG position switches. For practical sizing, plan for a real workload of about 147 N (roughly 60% of the 0.5 MPa rating), which translates to safely lifting a 12.5 kg mass vertically with a 2:1 safety margin. Air arrives via a 1/8" port, driving the 30-800 mm/s speed range.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CA Is Used
Package Diverter Gate
Actuates a heavy routing flap on a logistics conveyor, utilizing the 245.3 N push force to redirect parcels reliably over the 450 mm travel.
Textile Loom Tensioner
Pivots via the CA clevis to maintain tension arms on weaving machinery, where the stainless build withstands humid manufacturing conditions.
Vertical Carton Ejector
Pushes packed cartons from a staging shelf, safely handling loads up to 12.5 kg vertically thanks to the robust 25 mm bore.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CA the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore raises it to 402 N. The 450 mm stroke is well within the 500 mm standard limit for this bore, though at full extension the Ø10 mm rod is exposed to side-loading risks; ensure adequate guidance to prevent premature seal wear. The CA back cover provides an integrated pivot clevis, ideal for applications requiring angular alignment.
Remember that a standard double-acting cylinder drifts when air pressure is removed or the valve is centred. The TPU bumpers only soften the end-of-stroke impact and do not function as a braking mechanism. To suspend a load safely during an air loss event, incorporate an external pilot-operated check valve or a dedicated rod lock. Furthermore, as this unit has no internal magnet, adding position sensing requires switching to the -S variant.
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 MI25X450CA FAQ
This 25 mm bore cylinder features a 1/8" air 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.
No, because this specific model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Mounting options include LB foot, FA flange, SDB pivot, TC trunnion, and the CA rear clevis equipped on this unit.
