About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and rod resist mild corrosion, making it highly suitable for damp or washdown environments compared to painted alternatives. It features a 1/4" port and a 160 mm stroke.
Equipped with fixed TPU bumper pads to decelerate the piston at stroke ends, the riveted construction remains light and robust. Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. Plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety 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 MI32X160SU Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to redirect parcels reliably at high throughput.
Vertical Parts Press
Pushes lightweight bearings into housings on an assembly line, safely operating within the 241 N working load limit.
Washdown Valve Actuation
Cycles a process valve in a damp food-production cell, where the stainless-steel rod and barrel prevent mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160SU the Right Cylinder?
For lower force requirements, the Ø25 bore provides 245.3 N of push at 0.5 MPa, while stepping up to the Ø40 bore yields 628.3 N if your application demands more power. This Ø32 model strikes a strong balance for mid-range automation. The U back cover provides a 90-degree port orientation, easily pairing with LB foot, FA flange, SDB pivot, or TC trunnion hardware.
Note that a plain cylinder drifts when air is lost or the valve is centered, as the TPU bumpers only soften the stroke end rather than locking the load. To hold a vertical position securely, integrate an external rod lock or a pilot-operated check valve. At 160 mm, ensure your mounting arrangement minimizes side-load to prevent rod bending.
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 MI32X160SU FAQ
This double-acting cylinder uses a 1/4" port and an 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.
No, the base MI relies on fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning, look at the MIC variant. However, because this model includes the -S magnet, it fully supports CMSG, DMSG, and EMSG switches for position sensing.
