About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SR
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work over its 500 mm travel. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it a durable choice for damp or washdown environments where painted steel fails. Fixed TPU bumper pads absorb the impact at stroke extremes, and the built-in magnet (-S) directly supports CMSG, DMSG and EMSG position switches.
A 1/4" port feeds the 32 mm bore to generate this thrust, while the R back cover provides an axial-in port orientation for tight installations. For practical 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.

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 MI32X500SR Is Used
Pallet Divert Gate
Shifts heavy pallets transversely on a packaging line, utilizing the 402.2 N push force to overcome friction over the full 500 mm travel.
Parts Elevator Descent
Lowers stacked metal trays in a washdown bay, where the stainless barrel resists moisture and the TPU bumpers soften the final landing impact.
Long-Reach Pusher
Ejects completed machined parts from a CNC enclosure, using the R axial-in port to save space while a DMSG sensor confirms full extension.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SR the Right Cylinder?
When sizing this 500 mm stroke actuator, compare it against adjacent bores: a Ø25 generates 245.3 N push at 0.5 MPa, while a Ø40 steps up to 628.3 N. This model sits comfortably in the middle for heavier automation tasks. Because the 500 mm travel is the maximum standard stroke for this bore, ensure your mounting setup—whether using LB foot brackets, FA flanges, or TC trunnions—prevents rod bending and side-loading forces.
Note that venting or losing air pressure will cause the piston to drift; the TPU bumpers only decelerate the stroke end and do not function as a lock or brake. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your 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 MI32X500SR FAQ
This 32 mm bore cylinder features a 1/4" port and a Ø12 mm rod with an M10x1.25 male thread. 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, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not act as a brake. You must use an external rod lock or pilot check valve to hold a load securely.
