About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with confidence. The stainless-steel barrel and piston rod supply mild corrosion resistance, performing reliably in damp or washdown environments where painted alternatives degrade. Its riveted construction remains compact, while fixed TPU bumper pads absorb stroke-end impacts to protect the mechanism.
Featuring a 1/8" port and a 90-degree U back cover for versatile routing, the unit operates at speeds of 30-800 mm/s. Because this SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to an -S variant. For real-world sizing, plan for a safe working load of roughly 241 N, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100U Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to redirect packed cartons smoothly at high throughput speeds.
Volumetric Fill Valve
Opens and closes a large-bore fluid dispensing valve on a bottling line, relying on the stainless construction to withstand daily washdowns.
Press Pin Insertion
Drives a mechanical pin press for automotive subassembly, safely moving within the 241 N working load range to seat metal components precisely.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100U the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm model reduces the 0.5 MPa push force to 245.3 N, whereas moving up to a 40 mm bore yields 628.3 N. This SKU includes a 90-degree U back cover, so ensure your layout accommodates the side-exit port orientation. The 100 mm stroke is well within the 500 mm maximum standard, keeping the assembly rigid and minimizing rod-bending risks under typical loads.
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 end of travel and do not function as a braking mechanism. To suspend a load securely during an air failure, 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 MI32X100U 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, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an -S variant of the MI series to enable magnetic sensing capabilities.
