About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SR
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation tasks. The stainless-steel barrel and piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel or aluminium bodies degrade. A built-in piston magnet comes standard, allowing direct mounting of CMSG, DMSG or EMSG electronic and reed switches for position sensing.
The riveted construction keeps the unit compact while fixed TPU bumper pads absorb end-of-stroke impacts to protect the mechanism. Operating on filtered air at 0.15-1.0 MPa, it features a 1/8" port and an R axial-in rear cover for straightforward plumbing. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to safely lifting about 20.5 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SR Is Used
Package Diverting Gate
Actuates heavy routing flaps on high-speed logistics lines, using its 402.2 N push force to reliably redirect loaded cartons without stalling.
Pneumatic Press Platen
Drives a small stamping platen to seat bearings or clinch sheet metal, leveraging the 563 N output at 0.7 MPa for consistent downward pressure.
Pallet Stopper Arm
Deploys a robust stop arm on roller conveyors to halt heavy pallets, with the stainless build surviving humid or wash-down warehouse zones.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SR the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.3 N, while stepping up to a 40 mm bore increases it to 628.3 N. The 100 mm stroke is well within the 500 mm maximum standard stroke, keeping the rod bending risk low, though side loads should still be minimized via proper guide rails. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to fit your frame.
Note that the TPU bumpers only decelerate the piston near the stroke end; they do not function as an adjustable air cushion like the MIC variant. If the air supply drops or the valve is centered, the piston will drift and cannot hold a suspended load. For vertical applications requiring fail-safe holding, 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 MI32X100SR FAQ
This 32 mm bore cylinder uses a 1/8" air port and a M10x1.25 male rod thread. 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.
The -S suffix means a magnet is built-in, allowing CMSG, DMSG or EMSG switches to be fitted. It uses fixed TPU bumper pads to decelerate at stroke ends, not an adjustable air cushion. The Ø32 size is a non-ISO-6432 round-body format.
