About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X280SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with confidence. The stainless-steel barrel and piston rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. It features a 1/8" air port and a 280 mm stroke.
Fixed TPU bumper pads decelerate the piston at both stroke ends, while the round CM back cover offers a clean rear profile for straightforward mounting. Plan for a real working load of roughly 241 N, which safely lifts about 20.5 kg vertically with a 2:1 margin. The built-in -S magnet enables direct mounting of CMSG, DMSG or EMSG sensors.

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 MI32X280SCM Is Used
Package Diverting
Actuates heavy-duty routing gates on packaging lines, using its 402.2 N thrust to push dense cartons reliably at speed.
Textile Loom Tensioning
Maintains precise tension on heavy fabric rolls in humid dye houses, leveraging the stainless rod to prevent mild corrosion.
Pallet Stacking
Raises lower-tier pallet components vertically, safely lifting parts up to 20.5 kg through its 280 mm extension.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X280SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore yields 245.3 N of push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. This unit uses a 1/8" port and a male M10x1.25 rod thread. The 280 mm stroke is well within the 500 mm maximum, but at this length you should minimize side loads to prevent rod bending. Note that the TPU bumpers only decelerate the stroke end; they do not act as a brake. If the load must be held vertically when air is lost, add an external rod lock or pilot 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 MI32X280SCM FAQ
This 32 mm bore cylinder features a 1/8" air 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 maximum of 82 kgf at 1.0 MPa.
The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG electronic switches. For cushioning, it relies on fixed TPU bumper pads to decelerate the stroke end; it does not have an adjustable air cushion.
