About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X25R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation in tight spaces. The stainless-steel barrel and piston rod resist mild corrosion and washdowns, outperforming painted alternatives in damp environments. A short 25 mm stroke provides rapid, compact movement.
Equipped with fixed TPU bumper pads to decelerate the stroke end, it operates at speeds of 30-800 mm/s. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. For practical sizing, plan for a safe working load of roughly 241 N, which means it can vertically lift about 20.5 kg with a 2:1 safety margin. The 1/8" port and rear R axial-in cover orientation streamline plumbing in confined machinery layouts.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X25R Is Used
Stamping Pin Ejection
Provides 402.2 N of push at 0.5 MPa to eject formed metal pins from a stamping die rapidly over a 25 mm travel distance.
Heavy Package Diverter
Swings a heavy-duty diverter arm on a packaging line, using its 20.5 kg safe vertical lift capacity to re-route dense cartons.
Clamp Actuation
Secures wooden workpieces in a CNC routing cell, where the stainless construction withstands airborne wood dust and coolant mist.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X25R the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 generates 245.3 N of push at 0.5 MPa, while the larger Ø40 provides 628.3 N, giving you clear scaling boundaries for your force requirements. The 1/8" port matches the bore's airflow demands. If your application needs position feedback, you must select the -S magnet variant, as this standard model cannot host a sensor.
Because the 25 mm stroke is quite short, rod bending and side-load risks are minimal compared to longer travels. However, remember that a standard cylinder drifts when air is lost or the valve is centred; the TPU bumpers only soften the impact at stroke end and do not function as a brake. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve.
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 MI32X25R FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 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 features fixed TPU bumper pads for stroke-end deceleration rather than an adjustable air cushion.
