About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SUTC
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 25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted stainless barrel and rod shrug off mild corrosion, giving a real edge over painted alternatives in damp or washdown environments. For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means it lifts about 12.5 kg vertically with a 2:1 safety margin.
Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches. The U rear cover provides a 90-degree port orientation, while the included TC trunnion mount simplifies pivot installations. Fixed TPU bumper pads absorb stroke-end impact, operating reliably at 30-800 mm/s. The Ø25 dimension adheres to ISO 6432 mounting interfaces, dropping directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SUTC Is Used
Packaging Diverter
Pushes medium-weight cartons at 245.3 N on a packaging line, using the TC trunnion to pivot smoothly during lane sorting tasks.
Vertical Parts Lift
Raises small material bins weighing up to 12.5 kg, relying on the stainless build to resist humidity in storage environments.
Clamp Actuation
Secures aluminum extrusions for machining, using the -S magnet and DMSG switch to confirm clamp engagement before cutting begins.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SUTC the Right Cylinder?
When sizing this 25 mm bore, stepping down to the Ø20 MI yields 157.0 N of push at 0.5 MPa, whereas stepping up to the Ø32 MI provides 402.2 N. This model hits a strong middle ground for medium-force tasks. If your application must hold a load vertically during air loss or valve centering, note that the piston will drift; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. You must add an external rod lock or a pilot-operated check valve for secure load holding. The TC trunnion pairing with the U back cover is ideal for articulated mechanisms requiring pivoting freedom.
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 MI25X75SUTC FAQ
This 25 mm bore cylinder pushes 245.3 N and pulls 206.1 N at 0.5 MPa. At 0.7 MPa, it pushes 343.4 N and pulls 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.
No, the base MI features fixed TPU bumper pads that decelerate the stroke end but do not offer adjustable air cushioning; that is reserved for the MIC variant. Additionally, it cannot hold a load if air is lost, as the piston will drift. You need an external rod lock or pilot check valve for position holding.
