About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X20R
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X20R is a double-acting round-body mini cylinder built for compact, high-thrust tasks. Its stainless-steel barrel and piston rod shrug off mild corrosion, making it highly reliable in damp or washdown-prone environments compared to standard aluminium bodies. The 20 mm stroke strikes a balance for short clamping moves, and the rear R cover features an axial-in port to simplify tight plumbing layouts.
Because this SKU lacks the -S suffix, it cannot host CMSG, DMSG or EMSG magnetic switches. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. For practical sizing, 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 MI32X20R Is Used
Short-Stroke Stamping
Executes brief 20 mm stamping and marking actions on light-gauge sheet metal, utilizing the 402.2 N push force to create clean indentations.
Heavy Part Diverter
Pushes denser components off a conveyor belt in packaging lines, where the 32 mm bore provides enough thrust to move items without stalling.
Pallet Stopper Gate
Acts as a robust pneumatic stop gate for loaded pallets, relying on its stainless construction to endure humid warehouse conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X20R the Right Cylinder?
When sizing this 32 mm bore, dropping down to a 25 mm version reduces the 0.5 MPa push force to 245.3 N, while stepping up to a 40 mm bore yields 628.3 N. The 1/4" port matches the bore's air demand, and the male M10x1.25 rod thread handles secure mechanical attachments. This short 20 mm stroke minimizes rod-bending side-load risks.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU pads only soften the end-of-stroke impact and do not act as a brake. To suspend a load safely mid-cycle, fit an external rod lock or a pilot-operated check valve. If you require position feedback, select the -S magnet version instead of this non-sensing unit.
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 MI32X20R FAQ
This 32 mm bore cylinder features a 1/4" 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 force of 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must choose an MI32 variant with the -S suffix to use CMSG, DMSG or EMSG magnetic switches. Additionally, its fixed TPU bumper pads only decelerate the stroke end and do not function as an adjustable air cushion.
