About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X550SUTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial actuation tasks. The stainless-steel barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. It features a 1/8" port and a 550 mm stroke, which is a non-standard made-to-order length exceeding the 500 mm maximum for this bore.
Equipped with fixed TPU bumper pads to decelerate the stroke end, the unit includes a built-in magnet for CMSG, DMSG, or EMSG switches. Plan for roughly 241 N of actual work at 0.5 MPa, which safely lifts 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 MI32X550SUTC Is Used
Long-Reach Diverter
Pushes heavy packages across a sorting line using the 550 mm extended reach, relying on the 402.2 N thrust to redirect items without stalling.
Pallet Handling Gate
Operates a pivoting safety gate in humid logistics hubs where the stainless steel barrel prevents mild corrosion from frequent washdowns.
Automated Welding Arm
Actuates a long welding fixture, using the TC trunnion to manage the moment loads inherent to the 550 mm extended rod length.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X550SUTC the Right Cylinder?
This 32 mm bore generates 402.2 N push at 0.5 MPa, sitting between the 25 mm (245.3 N) and the 40 mm (628.3 N) options. The TC trunnion mount and U 90-degree back cover provide versatile installation angles for your framework. Because the 550 mm stroke exceeds the 500 mm standard, expect a made-to-order part where side-load and rod-bending forces are amplified.
The integrated magnet supports position sensing. Remember that a plain cylinder drifts when air is lost or the valve centers; the bumpers only soften the end of travel. To hold a load securely, 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 MI32X550SUTC FAQ
This 32 mm bore cylinder has a 1/8" port. 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 max of 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 stroke end and do not act as a brake. Use an external rod lock or pilot check valve to hold loads.
