About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CASDB
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in compact spaces. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Riveted construction keeps the body light, while fixed TPU bumper pads absorb stroke-end impact.
For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa, which equates to lifting about 12.5 kg vertically with a 2:1 safety margin. The CA rear pivot cover and included SDB pivot block allow straightforward angular mounting. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CASDB Is Used
Automated Clamping Arms
Drives heavy pivoting clamps on CNC machining fixtures using the CA clevis and SDB block, utilizing its 245 N push force to secure metal parts during milling.
Package Diverters
Actuates routing gates on packaging lines where the stainless build withstands occasional washdowns and the 50 mm stroke quickly redirects cardboard cartons.
Textile Loom Tensioning
Maintains tension on fabric guides in humid textile manufacturing environments, leveraging the corrosion-resistant stainless barrel for long service life.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CASDB the Right Cylinder?
When sizing this 25 mm bore, stepping down to a Ø20 unit drops the push force to 157 N at 0.5 MPa, whereas moving up to a Ø32 bore increases it to 402 N. This model includes the CA clevis back cover and an SDB pivot block, making it ideal for pivoting mechanisms rather than rigid flange mounts. Note that a plain double-acting cylinder drifts if air pressure is lost or the valve is centered; the TPU bumpers only decelerate the stroke end and do not function as a lock. Use an external rod lock or pilot check valve if the load must be held securely.
With a 50 mm stroke, side-load stress on the Ø10 rod remains minimal, but ensure the pivot block aligns with the load to prevent rod bending. If your application requires position feedback, you must select the -S magnet variant instead, as this configuration cannot host a sensor.
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 MI25X50CASDB FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG or EMSG switches. You must purchase the -S variant for position sensing. It uses the ISO 6432 mounting interface for standard brackets and features fixed TPU bumper pads, not adjustable air cushions.
