About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SUTC
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The riveted stainless barrel and Ø10 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. A built-in piston magnet allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
Because the Ø25 bore adheres to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. The 1/8" port feeds air to extend and retract the rod at 30-800 mm/s, while fixed TPU bumper pads absorb the impact at stroke ends. For practical sizing, plan for a safe working load of roughly 147 N, which means it can comfortably lift about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SUTC Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 245 N push force to redirect heavy cartons onto secondary tracks at high cycling speeds.
CNC Lathe Door Operation
Opens and closes a sliding machine tool door, leveraging the stainless build to resist coolant mist while the TC trunnion accommodates the pivot arc.
Pallet Component Pusher
Sweeps loose components into a palletizing station, safely moving parts weighing up to 12.5 kg vertically or horizontally with the calculated safe working load.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SUTC the Right Cylinder?
When sizing this 100 mm stroke unit, step down to the Ø20 bore if your application only requires 157 N of push at 0.5 MPa, or move up to the Ø32 bore for 402 N when heavier forces are needed. This specific configuration includes a U-type 90-degree rear cover and a TC trunnion mount, providing pivot flexibility for articulated mechanisms. The included -S magnet enables electronic or reed sensor tracking along the body.
Keep in mind that a standard double-acting cylinder drifts if air pressure drops or the valve is centered, as the TPU bumpers only decelerate the stroke end without locking the rod. To suspend a load safely mid-stroke, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit. Additionally, on this 100 mm stroke, ensure the front mounting is rigid to prevent rod side-loading and premature seal wear.
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 MI25X100SUTC FAQ
This Ø25 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. At 0.5 MPa it provides 245.3 N push and 206.1 N pull force. At 0.7 MPa the push increases to 343.4 N and pull to 288.5 N. 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; they do not act as a brake, so the rod will drift if air is lost. Use an external pilot check valve for load holding. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG, and EMSG position switches.
