About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial actuation tasks within a compact 35 mm stroke. The stainless-steel barrel and piston rod provide mild corrosion resistance, making it highly suitable for damp production zones where painted steel alternatives would degrade. Its riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at the stroke extremes. The rear R cover features an axial-in port orientation, simplifying downward plumbing in tight machine cells.
For practical sizing, plan for roughly 241 N of actual work at 0.5 MPa, which safely accounts for friction and system losses. This translates to lifting a 20.5 kg load vertically with a 2:1 safety margin. Air enters via a 1/8 inch port, and the 12 mm rod features an M10x1.25 male thread. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35R Is Used
Stamping Pin Ejection
Provides the 402.2 N push force needed to eject heavy metal pins from a stamping die within a tight 35 mm space.
Package Diverting Arm
Drives a heavy-duty diverter arm on a packaging conveyor, utilizing its stainless build to withstand washdown cycles.
Pallet Stop Gate
Acts as a robust stop gate for loaded pallets, safely halting 20 kg goods without exceeding the safe working load.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35R the Right Cylinder?
When sizing this 32 mm bore, compare your actual load against the 402.2 N push figure at 0.5 MPa. If your application requires less force, stepping down to the 25 mm bore yields 245.3 N, whereas moving up to the 40 mm bore provides 628.3 N. This 35 mm stroke is well within the 500 mm maximum, keeping the rod short and highly resistant to bending under high side loads. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The TPU bumpers only decelerate the piston near the stroke end; they do not function as a locking mechanism. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI32X35R FAQ
At 0.5 MPa, the push force is 402.2 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/8 inch air port.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG switches, you must purchase the -S variant. Additionally, this round-body mini cylinder uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
