About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X650SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion tasks. The 650 mm stroke on this Ø25 bore unit is a made-to-order length, exceeding the 500 mm standard maximum to provide extended travel for specialized equipment. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
Featuring a CA rear pivot cover and an integrated piston magnet (-S), the unit supports CMSG, DMSG, and EMSG position switches. Plan for a safe working load of roughly 147 N, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. The 1/8" port feeds air to both chambers, while fixed TPU bumper pads absorb the end-of-stroke impact.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X650SCA Is Used
Pallet Diversion Gate
Uses the extended 650 mm travel to push heavy pallets onto a secondary conveyor line, utilizing the 245.3 N push force to overcome friction.
Lab Sample Indexing
Moves delicate testing racks through a washdown station, where the stainless steel rod prevents mild corrosion from repeated chemical exposure.
Vertical Parts Descender
Lowers lightweight component trays from an overhead feeder, safely managing a 12.5 kg payload with a 2:1 safety margin during the descent.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X650SCA the Right Cylinder?
When sizing this actuator, consider the neighboring bores: the Ø20 generates 157.0 N of push at 0.5 MPa, while the larger Ø32 provides 402.2 N. If your application requires true position holding on air loss or valve centering, note that this standard cylinder will drift; an external rod lock or pilot-operated check valve is required for secure load holding. The integrated magnet allows seamless sensor pairing without external hardware.
Because the 650 mm travel significantly exceeds the 500 mm standard stroke for this bore, carefully evaluate side loading. A long 10 mm piston rod is susceptible to bending forces, so ensure rigid guidance on the driven payload to prevent premature seal wear. The CA clevis mount helps accommodate minor alignment deviations along the stroke axis.
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 MI25X650SCA FAQ
This Ø25 mm bore cylinder pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port and a 10 mm piston rod with an M10x1.25 male thread.
The Ø25 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. It features fixed TPU bumper pads that decelerate the stroke end but do not provide adjustable cushioning. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
